- Аннотация: Discovering spectral signs of sub-limation activity in September 2012 on four main-belt primitive asteroids (145) Adeona, (704) Interamnia, (779) Nina, and (1474) Beira at their perihelion dis-tances raised questions about the probable mass nature of this phenomenon on main-belt bodies that could contain free water ice. As is known, the mineral-ogy of solid rock bodies is sensitive to conditions of their origin. However, the orbital ellipticity of a small planet makes it possible to test the volatility of the body’s material depending on heliocentric distance and accompanying surface temperature changes. Now we are able to confirm this periodic process on Nina as it approached perihelion in September 2016.
