Sonnensystem Das Sonnensystem Fasziniert Die Menschen Bereits Seit Zehntausenden Sonnensystem Von Jahren WikiPress Sonnensystem Das Sonnensystem fasziniert die Menschen bereits seit Zehntausenden Sonnensystem von Jahren. Aus dieser Zeit stammen die ersten Beobachtungen der erd- nahen Planeten, des Erdmondes und auch der Sonne selbst. Die Positionen Entstehung, Forschung, Entwicklung dieser Himmelskörper waren bis in die letzten Jahrhunderte umstritten. Gerade in den letzten Jahrzehnten konnte eine ungeheure Fülle an Infor- mationen zu den Planeten und Monden angehäuft werden. Immer bessere Aus der freien Enzyklopädie Wikipedia Teleskope und Raumsonden bieten ein immer detaillierteres Bild des Son- zusammengestellt von nensystems und ihrer Planeten, Monde, Asteroiden und Kometen. Dieses Buch stellt diese neuen Forschungsergebnisse über die Himmelskörper Daniel Arnold kenntnisreich dar. Daniel Arnold ist am 16. September 1980 in Magdeburg geboren, ver- brachte seine Kindheit zunächst in Jena, Thüringen und später in Würz- burg, Bayern, wo er schließlich 2000 seine Schulzeit mit der Allgemeinen Hochschulreife abschloss. Nach Beendigung seine Zivildienstes begann er 2001 in Erlangen an der Universität zunächst Physik zu studieren und wechselte später auf Maschinenbau an derselben Universität. Schon vor seinem Engagement in Wikipedia ab dem Frühjahr 2004 schrieb er neben- bei vorwiegend an Schülerzeitungen mit. Er interessiert sich vorwiegend für Physik, Astronomie und (Computer-)Technik, schaut jedoch auch ger- ne über den Tellerrand und befasst sich außerdem mit Geschichte und Politik.

  • Surface Characteristics of Transneptunian Objects and Centaurs from Photometry and Spectroscopy
    Barucci et al.: Surface Characteristics of TNOs and Centaurs 647 Surface Characteristics of Transneptunian Objects and Centaurs from Photometry and Spectroscopy M. A. Barucci and A. Doressoundiram Observatoire de Paris D. P. Cruikshank NASA Ames Research Center The external region of the solar system contains a vast population of small icy bodies, be- lieved to be remnants from the accretion of the planets. The transneptunian objects (TNOs) and Centaurs (located between Jupiter and Neptune) are probably made of the most primitive and thermally unprocessed materials of the known solar system. Although the study of these objects has rapidly evolved in the past few years, especially from dynamical and theoretical points of view, studies of the physical and chemical properties of the TNO population are still limited by the faintness of these objects. The basic properties of these objects, including infor- mation on their dimensions and rotation periods, are presented, with emphasis on their diver- sity and the possible characteristics of their surfaces. 1.

  • Water Ice in 2060 Chiron and Its Implications for Centaurs and Kuiper Belt Objects
    Water Ice in 2060 Chiron and its Implications for Centaurs and Kuiper Belt Objects Jane X. Luu Sterrewacht Leiden Postbus 9513, 2300RA Leiden, The Netherlands David C. Jewitt1 Institute for Astronomy 2680 Woodlawn Drive, Honolulu, HI 96822 and Chad Trujillo1 Institute for Astronomy 2680 Woodlawn Drive, Honolulu, HI 96822 Received ; accepted Submitted to Ap. J. Letters, accepted 31 Jan 2000 1Visiting Astronomer, W. M. Keck Observatory, jointly operated by California Institute of Technology and the University of California. –2– ABSTRACT We report the detection of water ice in the Centaur 2060 Chiron, based on near-infrared spectra (1.0 - 2.5 µm) taken with the 3.8-meter United Kingdom Infrared Telescope (UKIRT) and the 10-meter Keck Telescope. The appearance of this ice is correlated with the recent decline in Chiron’s cometary activity: the decrease in the coma cross-section allows previously hidden solid-state surface features to be seen. We predict that water ice is ubiquitous among Centaurs and Kuiper Belt objects, but its surface coverage varies from object to object, and thus determines its detectability and the occurrence of cometary activity. Subject headings: comets – Kuiper Belt – solar system: formation 1. Introduction The Centaurs are a set of solar system objects whose orbits are confined between those of Jupiter and Neptune. Their planet-crossing orbits imply a short dynamical lifetime (106 107 yr). The current belief is that Centaurs are objects scattered from the Kuiper − Belt that may eventually end up in the inner solar system as short-period comets. The first discovered and brightest known Centaur, 2060 Chiron, is relatively well studied.

She had been pondering the craters left by comets and asteroids that smashed into Earth. Geologists had counted them and concluded that space strikes are rare events and had occurred mainly during the era of primordial mists. But, Abbott realized, this deduction was based on the number of craters found on land—and because 70 percent of Earth’s surface is water, wouldn’t most space objects hit the sea? So she began searching for underwater craters caused by impacts VIDEO: "TARGET EARTH" rather than by other forces, such as volcanoes.

If Abbott is right, then you may be here today, reading this magazine, only because by sheer chance those objects struck the ocean rather than land.

The lunar profile is drawn using data from the Kaguya lunar surveyor, which became available after this event. The path the star followed across the lunar landscape is shown for one set of observers (Murray Forbes and Frank Andrews) by the trail of white circles. There are several instances where a stepped event was seen, due to the two brightest components disappearing or reappearing. See page 61 for more details.

  • Transneptunian Object Taxonomy 181
    Fulchignoni et al.: Transneptunian Object Taxonomy 181 Transneptunian Object Taxonomy Marcello Fulchignoni LESIA, Observatoire de Paris Irina Belskaya Kharkiv National University Maria Antonietta Barucci LESIA, Observatoire de Paris Maria Cristina De Sanctis IASF-INAF, Rome Alain Doressoundiram LESIA, Observatoire de Paris A taxonomic scheme based on multivariate statistics is proposed to distinguish groups of TNOs having the same behavior concerning their BVRIJ colors. As in the case of asteroids, the broadband spectrophotometry provides a first hint about the bulk compositional properties of the TNOs’ surfaces. Principal components (PC) analysis shows that most of the TNOs’ color variability can be accounted for by a single component (i.e., a linear combination of the col- ors): All the studied objects are distributed along a quasicontinuous trend spanning from “gray” (neutral color with respect to those of the Sun) to very “red” (showing a spectacular increase in the reflectance of the I and J bands). A finer structure is superimposed to this trend and four homogeneous “compositional” classes emerge clearly, and independently from the PC analy- sis, if the TNO sample is analyzed with a grouping technique (the G-mode statistics). The first class (designed as BB) contains the objects that are neutral in color with respect to the Sun, while the RR class contains the very red ones. Two intermediate classes are separated by the G mode: the BR and the IR, which are clearly distinguished by the reflectance relative increases in the R and I bands. Some characteristics of the classes are deduced that extend to all the objects of a given class the properties that are common to those members of the class for which more detailed data are available (observed activity, full spectra, albedo).

Burbine Jr. Submitted to the Department of Earth, Atmospheric, and Planetary Sciences on December 30, 1999 in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Planetary Sciences ABSTRACT Near-infrared spectra (-0.90 to ~1.65 microns) were obtained for 196 main-belt and near-Earth asteroids to determine plausible meteorite parent bodies. These spectra, when coupled with previously obtained visible data, allow for a better determination of asteroid mineralogies. Over half of the observed objects have estimated diameters less than 20 k-m. Many important results were obtained concerning the compositional structure of the asteroid belt. A number of small objects near asteroid 4 Vesta were found to have near-infrared spectra similar to the eucrite and howardite meteorites, which are believed to be derived from Vesta.
