# List of asteroids on SwissEph CD-ROM # ==================================== # At the same time a brief introduction into asteroids # ==================================================== # Dieter Koch # updated 8 Oct 2005 # # # Ephemerides of all of the asteroids mentioned below # can be found on the SwissEph CD-ROM. # For complete Ephemerides of ALL asteroids, order our # special asteroid CD-ROMS. # # Literature: # Lutz D. Schmadel, Dictionary of Minor Planet Names, # Springer, Berlin, Heidelberg, New York # Charles T. Kowal, Asteroids. Their Nature and Utilization, # Whiley & Sons, 1996, Chichester, England # # # What is an asteroid? # -------------------- # # Asteroids are small planets. Because there are too many # of them and because most of them are quite small, # astronomers did not like to call them "planets", but # invented names like "asteroid" (Greek "star-like", # because through telescopes they did not appear as planetary # discs but as star-like points) or "planetoid" (Greek # "similar to a planet"). However they are also often # called minor planets. # The minor planets can roughly be divided into two groups. # There are the inner asteroids, the majority of which # circles in the space between Mars and Jupiter, and # there are the outer asteroids, which have their realm # beyond Neptune. The first group consists of rather # dense, earth-like material, whereas the Transneptunians # mainly consist of water ice and frozen gases. Many comets # are descendants of the "asteroids" (or should one say # "comets"?) belt beyond Neptune. The first Transneptunian # objects (except Pluto) were discovered only after 1992 # and none of them has been given a name as yet. # # # The largest main belt asteroids # ------------------------------- # Most asteroids are actually only debris of collisions # of small planets that formed in the beginning of the # solar system. Only the largest ones are still more # or less complete and round planets. 1 Ceres # 913 km goddess of corn and harvest 2 Pallas # 523 km goddess of wisdom, war and liberal arts 4 Vesta # 501 km goddess of the hearth fire 10 Hygiea # 429 km goddess of health 511 Davida # 324 km after an astronomer David P. Todd 704 Interamnia # 338 km "between rivers", ancient name of # its discovery place Teramo 65 Cybele # 308 km Phrygian Goddess, = Rhea, wife of Kronos-Saturn 52 Europa # 292 km beautiful mortal woman, mother of Minos by Zeus 87 Sylvia # 282 km 451 Patientia # 280 km patience 31 Euphrosyne # 270 km one of the three Graces, benevolence 15 Eunomia # 260 km one of the Hours, order and law 324 Bamberga # 252 km after a city in Bavaria 3 Juno # 248 km wife of Zeus 16 Psyche # 248 km "soul", name of a nymph # Asteroid families # ----------------- # Most asteroids live in families. There are several kinds # of families. # - There are families that are separated from each other # by orbital resonances with Jupiter or other major planets. # - Other families, the so-called Hirayama families, are the # relics of asteroids that broke apart long ago when they # collided with other asteroids. They still share similar # orbital qualities. # - Third, there are the Trojan asteroids that are caught # in regions 60 degrees ahead or behind a major planet # (Jupiter or Mars) by the combined gravitational forces # of this planet and the Sun. # Near Earth groups: # ------------------ # # Aten family: they cross Earth; mean distance from Sun is less than Earth 2062 Aten # an Egyptian Sun god 2100 Ra-Shalom # Ra is an Egyptian Sun god, Shalom is Hebrew "peace" # was discovered during Camp David mid-east peace conference # Apollo family: they cross Earth; mean distance is greater than Earth 1862 Apollo # Greek Sun god 1566 Icarus # wanted to fly to the sky, fell into the ocean # Icarus crosses Mercury, Venus, Earth, and Mars # and has his perihelion very close to the Sun 3200 Phaethon # wanted to drive the solar chariot, crashed in flames # Phaethon crosses Mercury, Venus, Earth, and Mars # and has his perihelion very close to the Sun 69230 Hermes # Greek name of Mercury; # discovered and lost in 1937, rediscovered in 2003 # Amor family: they cross Mars, approach Earth 1221 Amor # Roman love god 433 Eros # Greek love god 719 Albert # dicovered and lost in 1911 rediscovered in 2000 # Mars Trojans: # ------------- 5261 Eureka a mars Trojan # Main belt families: # ------------------- # Hungarias: an asteroid group at 1.95 AU 434 Hungaria # after Hungary # Floras: a Hirayama family at 2.2 AU 8 Flora # goddess of flowers # Phocaeas: an asteroid group at 2.36 AU 25 Phocaea # maritime town in Ionia # Koronis family: a Hirayama family at 2.88 AU 158 Koronis # mother of Asklepios by Apollo # Eos family: a Hirayama family at 3.02 AU 221 Eos # goddess of dawn # Themis family: a Hirayama family at 3.13 AU 24 Themis # goddess of justice # Hildas: an asteroid belt at 4.0 AU, in 3:2 resonance with Jupiter # -------------------------------------------------------------- # The Hildas have fairly eccentric orbits and, at their # aphelion, are very close to the orbit of Jupiter. However, # at those times, Jupiter is ALWAYS somewhere else. As # Jupiter approaches, the Hilda asteroids move towards # their perihelion points. 153 Hilda # female first name, means "heroine" # a single asteroid at 4.26 AU, in 4:3 resonance with Jupiter 279 Thule # mythical center of Magic in the uttermost north # Jupiter Trojans: # ---------------- # Only the Trojans behind Jupiter are actually named after Trojan heroes, # whereas the "Trojans" ahead of Jupiter are named after Greek heroes that # participated in the Trojan war. However there have been made some mistakes, # i.e. there are some Trojan "spies" in the Greek army and some Greek "spies" # in the Trojan army. # Greeks ahead of Jupiter: 624 Hector # Trojan "spy" in the Greek army, by far the greatest # Trojan hero and the greatest Trojan asteroid 588 Achilles # slayer of Hector 1143 Odysseus # Trojans behind Jupiter: 1172 Äneas 3317 Paris 884 Priamus # Jupiter-crossing asteroids: # --------------------------- 3552 Don Quixote # perihelion near Mars, aphelion beyond Jupiter; # you know Don Quixote, don't you? 944 Hidalgo # perihelion near Mars, aphelion near Saturn; # after a Mexican national hero 5335 Damocles # perihelion near Mars, aphelion near Uranus; # the man sitting below a sword suspended by a thread # Centaurs: # --------- 2060 Chiron # perihelion near Saturn, aphelion near Uranus; # also a member of the comets catalogue (95P Chiron) # because it has cometary activity # educator of heros, specialist in healing and war arts 5145 Pholus # perihelion near Saturn, aphelion near Neptune # seer of the gods, keeper of the wine of the Centaurs 7066 Nessus # perihelion near Saturn, aphelion in Pluto's mean distance # ferryman, killed by Hercules, kills Hercules # Neptune Trojans: # ---------------- # none named by Feb 2004 # Plutinos: # --------- # These are objects with periods similar to Pluto, i.e. objects # that resonate with the Neptune period in a 3:2 ratio. # There are no Plutinos included in Swiss Ephemeris so far, but # PLUTO himself can be considered a Plutino type asteroid! 28978 Ixion # 1060 km diameter 90482 Orcus # 1700 km, largest Plutino by Oct 2005 (besides Pluto himself) # Cubewanos: # ---------- # These are non-Plutino objects with periods greater than Pluto. # The word "Cubewano" is derived from the preliminary designation # of the first-discovered Cubewano: 1992 QB1 # to be named after creation deities 15760 1992 QB1 # first-discovered Cubewano, 280 km diameter 20000 Varuna # 980 km 50000 Quaoar # largest Cubewano by Feb 2004: 1250 km # Scattered-Disk Objects: # ---------------------- # Highly eccentric trans-Neptunian orbits 90377 Sedna # perihelion 76 = AU, aphelion = 913 AU, period = 11000 years # diameter = 1700 km # strange bodies # -------------------- 20461 Dioretsa # a retrograde asteroid at Period = 115 years (a=23.757) # perihelion = 2.4 AU aphelion = 45 AU, incl = 160 # this is a rather comet-like orbit # Asteroids that challenge hypothetical planets astrology # ------------------------------------------------------- 42 Isis # not identical with "Isis-Transpluto" # Egyptian lunar goddess 763 Cupido # different from Witte's Cupido # Roman god of sexual desire 4341 Poseidon # not identical with Witte's Poseidon # Greek name of Neptune 4464 Vulcano # compare Witte's Vulkanus # and intramercurian hypothetical Vulcanus # Roman fire god 5731 Zeus # different from Witte's Zeus # Greek name of Jupiter 1862 Apollo # different from Witte's Apollon # Greek god of the Sun 398 Admete # compare Witte's Admetos # "the untamed one", daughter of Eurystheus # Asteroids that challenge Dark Moon/Lilith astrology # -------------------------------------------- 1181 Lilith # not identical with Dark Moon 'Lilith' # first evil wife of Adam 3753 Cruithne # also called a "second moon" of earth; # actually not a moon, but an asteroid that # orbits around the sun in a certain resonance # with the earth. # After the first Celtic group to come to the British Isles. # Also try the two points 60 degrees in front of and behind the # Moon, the so called Lagrange points, where the combined # gravitational forces of the earth and the moon might imprison # rocks and stones.
