ИСТИНА

Adeona family is a large asteroid family that formed from the supposed parent body 145 Adeona. Its spectral type is that of a carbonaceous C-type, with currently 2,236 asteroids identified as family members. Based upon simulation studies, the Adeonian family is believed to be no more than 794±194 My old, compared to a typical asteroid family age of 1–2 billion years. Taking into account the recent detection of sublimation-dust activity of Adeona near perihelion, the surface material may contain some amount of water ice or some local exposition of it (possibly due to an impact event). It can be assumed that a significant part of the asteroids of the family under consideration is close in origin to 145 Adeona and should have similar properties, including the suggested presence of water ice in its composition and manifestations of sublimation activity near perihelion/
