Conference abstract Asteroids, Comets, Meteors Helsinki, 2014 Don Quixote — a possible parent body of a meteor shower R. Rudawska1 and J. Vaubaillon2 1Faculty of Mathematics, Physics and Informatics, Comenius University, Mlynská dolina, Bratislava, SK-84248 Slovakia 2Institut de Mécanique Céleste et de Calcul des Éphémérides - Observatoire de Paris, 77 avenue Denfert-Rochereau, 75014 Paris, France This talk addresses the topic of meteoroid stream parent body in relation to meteor showers observed on the Earth. We carry out a further search to investigate the possibility of meteor shower observations caused by particles ejected from (3552) Don Quixote. The (3552) Don Quixote asteroid was discovered in 1983 as an Amor asteroid. The Tisserand parameter for the orbit has a value of 2.315 with respect to Jupiter, which indicates a comet-like orbit. The diameter of the object calculated from the absolute magnitude, is in the range of 12.3–24.5 km. It all makes Don Quixote a good candidate for a short-period comet among known near-Earth objects, which the recently observed cometary activity conﬁrms [1]. We have investigated the orbital evolution of the meteoroid stream originated from Don Quixote. If the object was active in the past, it might be a parent body for a meteor shower observed on the Earth. The model for the generation and evolution of the meteoroid stream in the Solar System is taken from [2]. The asteroid’s orbital elements and physical properties are taken from the JPL horizons website. The ejections of meteoroids from the asteroid surface took place when the asteroid was passing its perihelion between 5000 B.C. and 2013 A.D. Next, the orbits of ejected meteoroids were integrated to the year 2050. If a meteoroid is suﬃciently close to the Earth, its orbital parameters are saved and compared with known showers.

Summary: Phobos and Deimos, Mars’ two moons, are associated with significant planetary protection knowledge gaps for human missions, that may be filled by a low cost robotic reconnaissance mission focused on elucidating their origin and volatile content.

Box 6010, Northern Arizona University, Flagstaff, AZ 86011, USA (Received -; Revised -; Accepted -) Submitted to PSJ ABSTRACT We present a deep imaging and spectroscopic search for emission from (3200) Phaethon, a large near-Earth asteroid that appears to be the parent of the strong Geminid meteoroid stream, using the 4.3 m Lowell Discovery Telescope. Observations were conducted on 2017 December 14{18 when Phaethon passed only 0.07 au from the Earth. We determine the 3σ upper level of dust and CN production rates to be 0.007{0.2 kg s−1 and 2:3 1022 molecule s−1 through narrowband imaging. A search × in broadband images taken through the SDSS r' filter shows no 100-m-class fragments in Phaethon's vicinity. A deeper, but star-contaminated search also shows no sign of fragments down to 15 m. Optical spectroscopy of Phaethon and comet C/2017 O1 (ASASSN) as comparison confirms the absence of cometary emission lines from 24 25 −1 Phaethon and yields 3σ upper levels of CN, C2 and C3 of 10 {10 molecule s , 2 orders of magnitude higher than the CN constraint placed∼ by narrowband imaging, due to the much narrower on-sky aperture of the spectrographic slit.

Endogenous Surface Processes on Asteroids, Comets, and Meteorite
Lunar and Planetary Science XXIX 1203.pdf ENDOGENOUS SURFACE PROCESSES ON ASTEROIDS, COMETS AND METEORITE PARENT BODIES. Derek W. G. Sears, Cosmochemistry Group, Department of Chemistry and Biochemistry, University of Arkansas, Fayetteville, Arkansas 72701, USA. It is known that (i) almost half of the known asteroids are CI- or CM-like, and these meteorites are 10-20% water; (ii) many asteroids have water on their surfaces despite impact heating and evaporative drying; (iii) many asteroids, including Apollo-Amor asteroids that have been linked to the ordinary chondrites, are possibly related to comets. It is therefore suggested that endogenous processes involving the mobilization and loss of water and other volatile compounds on meteorite parent bodies should be considered in explaining the properties of ordinary chondrite meteorites. It is suggested that water and other volatile compounds from the interior of the meteorite parent body passing through the unconsolidated surface layers produced many of the major meteorite properties, including the aerodynamic and gravitational sorting of their components, and occasional aqueous alteration. Asteroids are almost certainly the immediate parent bodies of most meteorites (1), and some asteroids could be cometary in origin (2,3). There is considerable uncertainty as to which meteorite properties reflect processes occurring on the meteorite parent body (MPB) and which occurred in interstellar or interplanetary space (e.g. 4,5). The impact history and the formation of regoliths on asteroids (and thus MPB) are often discussed (6,7), but not the possibility of endogenous surface alteration processes. Many asteroids have CI- or CM-like surfaces (8), and these meteorites are 10-20 percent total water (9).

Near-Earth Asteroid Is Really a Comet 10 September 2013
Near-Earth asteroid is really a comet 10 September 2013 asteroid's, which tend to be more circular—so people thought it was one that had shed all its ice deposits." Using the Spitzer Space Telescope operated by the Jet Propulsion Laboratory at the California Institute of Technology under contract with NASA, the team—led by Michael Mommert of Northern Arizona University—reexamined images of Don Quixote from 2009 when it was in the part of its orbit closest to the Sun, and found it had a coma and a faint tail. Emery also reexamined images from 2004, when it The image displays Don Quixote's orbit. Credit: Josh was at its farthest distance from the sun, and Emery determined that the surface is composed of silicate dust, which is similar to comet dust. He also determined that Don Quixote did not have a coma or tail at this distance, which is common for comets Some things are not always what they seem—even because they need the sun's radiation to form the in space. For 30 years, scientists believed a large coma and the sun's charged particles to form the near-Earth object was an asteroid. Now, an tail. The researchers also confirmed Don Quixote's international team including Joshua Emery, size and the low, comet-like reflectivity of its assistant professor of earth and planetary sciences surface. at the University of Tennessee, Knoxville, has discovered it is actually a comet. Called 3552 Don Quixote, the body is the third largest near-Earth object—mostly rocky bodies, or asteroids, that orbit the Sun in the vicinity of Earth.

Fernańdez,1 David C. Jewitt,1 and Scott S. Sheppard1,2 Institute for Astronomy, University of Hawai‘i at Manoa,¯ 2680 Woodlawn Drive, Honolulu, HI 96822; [email protected], [email protected], [email protected] Received 2005 January 30; accepted 2005 March 24 ABSTRACT We present the results of a mid-infrared survey of 26 asteroids in comet-like orbits, including six Damocloids and six near-Earth asteroids (NEAs). We define a ‘‘comet-like’’ orbit as one having a Tisserand invariant TJ under 3 (but only including objects that are NEAs or otherwise unusual). Visible-wavelength data were also obtained, so geo- metric albedos (in the Cousins R band) and effective radii are presented for 25 objects (plus one more with 3 ' limits) as derived using the NEA Thermal Model. Nine of our objects were observed at two or more mid-infrared wave- lengths, and in all cases the low-thermal inertia thermal model was found to be applicable, with various values of the beaming parameter. Our work more than quintuples the total number of observationally constrained albedos among TJ < 3 asteroids to 32. Defining the ‘‘comet-like’’ albedos as those below 0.075, we find that 64% 5% of the sample has comet-like albedos. Objects in comet-like orbits with comet-like albedos are candidates forÆbeing dormant or extinct comets. Indeed, one of our targets, 2001 OG108, became active again a few months after our observations.

Dark Primitive Asteroids Account for a Large Share of K/Pg-Scale Impacts on the Earth
Dark Primitive Asteroids Account for a Large Share of K/Pg-Scale Impacts on the Earth David Nesvorn´y, William F. Bottke, Simone Marchi Department of Space Studies, Southwest Research Institute, 1050 Walnut St., Suite 300, Boulder, CO 80302, USA ABSTRACT A dynamical model for large near-Earth asteroids (NEAs) is developed here to understand the occurrence rate and nature of Cretaceous-Paleogene (K/Pg) scale impacts on the Earth. We ﬁnd that 16–32 (2–4) impacts of diameter D > 5 km (D > 10 km) NEAs are expected on the Earth in 1 Gyr, with about a half of impactors being dark primitive asteroids (most of which start with semimajor axis a > 2.5 au). These results explain why the Chicxulub crater, the third largest impact structure found on the Earth (diameter ≃ 180 km), was produced by impact of a carbonaceous chondrite. They suggest, when combined with previously published results for small (D . 1 km) NEAs, a size-dependent sampling of the main belt. We conclude that the impactor that triggered the K/Pg mass extinction ≃ 66 Myr ago was a main belt asteroid that quite likely (≃ 60% probability) originated beyond 2.5 au. Subject headings: Near-Earth objects; Asteroids, dynamics; Impact processes; Cratering; Astrobiology 1. Introduction arXiv:2107.03458v1 [astro-ph.EP] 7 Jul 2021 The Earth impact record accounts for ∼200 recognized crater structures and ∼50 de- posits (Schmieder and Kring, 2020). This collection is largely incomplete and contains severe biases. The impact age distribution, inferred from isotopic and stratigraphic analyses, shows that a great majority of preserved terrestrial craters formed in the last ∼650 Myr (Mazrouei et al., 2019; Keller et al., 2019).

Don Quixote – a Possible Parent Body of a Meteor Shower Regina Rudawska1 and Jérémie Vaubaillon2
Proceedings of the IMC, Giron, 2014 1 Don Quixote – a possible parent body of a meteor shower Regina Rudawska1 and Jérémie Vaubaillon2 1Faculty of Mathematics, Physics and Informatics, Comenius University, Bratislava, Slovakia [email protected] 2IMCCE – Observatoire de Paris, Paris, France [email protected] Here we are interested in whether the meteoroid stream of (3552) Don Quixote can generate some observed meteor showers. We have showed that particles originating from Don Quixote particles produce two meteor showers at Earth: κ Lyrids and August μ Draconids. 1 (3552) Don Quixote below the conventional threshold value which assumed when establishing orbits similarity, i.e. 0.20 (Babadzhanov The (3552) Don Quixote asteroid was discovered in 1983 et al., 2013). Similarly, the values of DV are below the usual and categorized as Amor asteroid. The Tisserand parameter threshold value of 0.08 (Jopek et al., 2008; Rudawska et al., for the orbit has a value of 2,315 with respect to Jupiter, 2012). which indicates a comet-like orbit. The diameter of the object as calculated from the absolute magnitude is in the range of 12,3 – 24,5 km. This all makes Don Quixote a good candidate for a short-period comet among known NEOs, which has been confirmed by recent observations of some cometary activity (Momment et al., 2014). 2 Methodology We have investigated the orbital evolution of the meteoroid stream originating from Don Quixote. For this purpose, we modelled the generation and evolution of the meteoroid stream in the Solar System. The ejections of meteoroids from the asteroid's surface took place when the asteroid was passing its perihelion between 5000 B.C.

The review contains the most recent data on near-Earth objects such as their sizes and densities, rotation and shapes, taxonomy and mineralogy, optical properties and structure of their surfaces, binary systems among the NEOs and internal structure of asteroids and comets constituted the NEO population. Keywords. Asteroids, near-Earth objects, physical properties, internal structure. 1. Introduction Near-Earth objects (NEOs) are deﬁned as asteroids and comets having orbits with perihelion distances of 1.3 AU or less. About 30% of the entire NEO population may reside in orbits having a Jovian Tisserand parameter <3, and among them roughly half are observed to have comet-like physical properties such as albedos and spectra. Thus, about 10-15% of the NEO population may be comprised by extinct or dormant comets (Lupishko & Lupishko 2001; Binzel & Lupishko 2006; Michel & Bottke 2009). The rest are the near-Earth asteroids, which are traditionally divided into three groups (the relative abundances are estimated by Bottke et al. (2002)): Amor a 1.0 AU 1.017 < q 1.3 AU (32 ± 1%) Apollo a 1.0 AU q < 1.017 AU (62 ± 1%) Aten a < 1.0 AU Q > 0.983 AU (6 ± 1%) Besides, there is an additional group of rather dangerous asteroids whose orbits reside entirely inside of the Earth’s one (Q < 0.983 AU).

Ice & Stone 2020 WEEK 45: NOVEMBER 1-7 Presented by The Earthrise Institute # 45 Authored by Alan Hale This week in history NOVEMBER 1 2 3 4 5 6 7 NOVEMBER 1, 1577: Observers in Peru make the first sighting of the Great Comet of 1577. This comet, a brilliant object which is often referred to as “Tycho Brahe’s Comet” and which is one of the most important scientific comets in history, is next week’s “Comet of the Week.” NOVEMBER 1, 1948: Observers on the ground near Nairobi, Kenya, as well as in a Royal Air Force plane flying at 4000 meters, detect a bright comet near the sun during a total solar eclipse. The Eclipse Comet of 1948 and other “eclipse comets” are the subject of a previous “Special Topics” presentation. NOVEMBER 1, 1975: University of California astronomer Martin Cohen publishes a paper announcing the likely presence of water ice surrounding the young solar-type star HL Tauri. A protoplanetary disk has since been detected surrounding this star. The significance of Cohen’s discovery is discussed in a previous “Special Topics” presentation. The protoplanetary disc surrounding the young star HL Tauri is seen in this sharp image from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. It reveal substructures within the disc that have never been seen before and even show the possible positions of planets forming in the dark patches within the system. Courtesy ALMA (ESO/NAOJ/NRAO).
