Bill Hanagan To start off, I’d like to thank Bill McKibben for his LAST CALL for the presentation at the April meeting on the Ancient Astronomy of Machu Picchu and Greg Lee for his presentation on DAS Dinner Meeting “What’s Up in the Sky”. If you missed the April meeting, you also missed my presentation on the sizing, positioning, and th surface quality of Newtonian secondary mirrors. Tuesday, May 17 Our May meeting is the annual “dinner” meeting of the DAS and it will be held on Tuesday, May 17 at the Christiana You’ll need to call Treasurer McKibben Hilton, the same location as last year. Social hour begins at at this late hour for Reservations. 6:00 P.M. followed by dinner at 7:00 P.M. After dinner, we’ll view a short video of time lapse astrophotos followed by the Andrew K. Johnston presentation of the Amateur Astronomer of the Year Award. We’ll conclude the evening with a talk titled “Navigating across from the the Solar System” by Mr. Andrew K. Johnston from the National Smithsonian Air and Space Museum. Mr. Johnston is the co-author of the “Smithsonian Atlas of Space Exploration” and his talk will give National Air & us a look at the history and technology of solar system explora- tion.

    A look at the capture mechanisms of the “Temporarily Captured Asteroids” of the Earth By Hodei URRUTXUA1) and Claudio BOMBARDELLI2) 1)Astronautics Group, University of Southampton, United Kingdom 2)Space Dynamics Group, Technical University of Madrid, Spain (Received April 17th, 2017) Temporarily captured asteroids of the Earth are a newly discovered family of asteroids, which become naturally captured in the vicinity of the Earth for a limited time period. Thus, during the temporary capture these asteroids are in energetically favorable condi- tions, which makes them appealing targets for space missions to asteroids. Despite their potential interest, their capture mechanisms are not yet fully understood, and basic questions remain unanswered regarding the taxonomy of this population. The present work looks at gaining a better understanding of the key features that are relevant to the duration and nature of these asteroids, by analyzing patterns and extracting conclusions from a synthetic population of temporarily captured asteroids.

As of 2017, this catalog presents data for 53 436 asteroids observed in at least two near-infrared filters (Y, J, H, or Ks). Among these asteroids, we find information for 6299 belonging to collisional families with both Y J and J Ks colors defined. The work presented here complements the data from SDSS and NEOWISE, and allows a detailed description− of− the overall composition of asteroid families. We derived a near-infrared parameter, the ML∗, that allows us to distinguish between four generic compositions: two different primitive groups (P1 and P2), a rocky population, and basaltic asteroids. We conducted statistical tests comparing the families in the MOVIS catalog with the theoretical distributions derived from our ML∗ in order to classify them according to the above-mentioned groups. We also studied the background populations in order to check how similar they are to their associated families.

    PYTS/ASTR 206 – Comets 1 Announcements HW6 available today, due in a week Use Kevin as the TA for this one 2 In-class assignments left in 3 lectures PYTS/ASTR 206 – Comets 2 Comets PTYS/ASTR 206 – The Golden Age of Planetary Exploration Shane Byrne – [email protected] PYTS/ASTR 206 – Comets 3 In this lecture… Observations of comets What are comets? Composition and structure Cometary tails Ion and dust tails Where do comets come from? Orbits of comets Oort cloud Scattered Kuiper Belt PYTS/ASTR 206 – Comets 4 Observations of comets Comets have been known from ancient times Thought to foreshadow disasters and major battles Pre-telescopes the known solar system was a pretty empty place Moon and the Sun Mercury, Venus, Mars, Jupiter, Saturn And COMETS No Uranus No Neptune No planetary Moons (except ours) No Asteroids No Kuiper Belt Objects PYTS/ASTR 206 – Comets 5 People have recorded comet sightings for millennia 167 BC 687 AD 1986 AD PYTS/ASTR 206 – Comets 6 Ancient Greeks thought comets were atmospheric phenomena In the west this went unchallenged until telescopes came along Tycho Brahe’s parallax measurements proved this wrong Comets were much further away than the Moon Renaissance astronomers thought comets moved in straight lines through the solar system Even Kepler argued they shouldn’t follow elliptical orbits like the planets In the 1680s astronomers tracked a comet and showed it had an elliptical orbit Comets were solar system objects – just like planets PYTS/ASTR 206 – Comets 7 Newton finally
