Its surface is very dark, and, based upon its classification as a C-type asteroid, is probably composed of primitive carbonaceous material. The spectra of the asteroid displays evidence of aqueous alteration. 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.Schmadel Lutz D.

The returned signal matched an effective diameter of 151 ± 18 km. This is consistent with the asteroid dimensions computed through other means.Magri Christopher Nolan Michael C. Ostro Steven J.

The latter was consistent with a diameter of 151 km.http://mpocc.astro.cz/world/mpocc1.txt Observed minor planet occultation events David Dunham July 26, 2005 June 3, 2017http://sendaiuchukan.jp/data/occult-e/occult-e.html Results of Asteroidal occultation Sendai Space Hall June 3, 2017http://sendaiuchukan.jp/data/occult/0502adeona-red.gif Occultation of (145) Adeona on 2005.2.3 Sendai Space Hall June 3, 2017 The Dawn mission team discussed performing a flyby of this object, however NASA decided against it in July 2016.http://www.nasa.gov/feature/new-horizons-receives-mission-extension-to-kuiper-belt-dawn-to-remain-at-ceres New Horizons Receives Mission Extension to Kuiper Belt, Dawn to Remain July 2016 At the time this was considered Dawn was orbiting the large asteroid/dwarf planet 1 Ceres, and went on studying that body later that year.http://www.jpl.nasa.gov/news/news.php?feature=6678 New Ceres Views as Dawn Moves Higher NASAJet Propulsion Laboratory Elizabeth Landau November 18, 2016 November 20, 2016 Dawn had previously orbited asteroid 4 Vesta, before traveling to Ceres.
