145 Adeona
145 Adeona is a rather large main-belt asteroid. Its surface is very dark,〔 and, based upon its classification as a C-type asteroid, is probably composed of primitive carbonaceous material. The Adeona family of asteroids is named after it. It was discovered by C. H. F. Peters on June 3, 1875, from the observatory at Hamilton College, Clinton, New York. Peters named it after Adeona, the Roman goddess of homecoming, because he had recently returned from a journey across the world to observe the transit of Venus. Peters also discovered 144 Vibilia on the same night.〔Lutz D. Schmadel, (''Dictionary of Minor Planet Names'', p.28 ).〕 During 2001, 145 Adeona was observed by radar from the Arecibo Observatory. The return signal matched an effective diameter of 151 ± 18 km. This is consistent with the asteroid dimensions computed through other means.〔 Adeona has been observed to occult a star once, on July 9, 2002. ==References==
