There is an apparent difference in the albedo distribution of the asteroids as a function of size, however, this effect is probably an artifact due to a combination of factors such as faint source flux overestimation and confusion with faint background sources.作者: 后退 時間: 2025-3-25 00:20 作者: Amenable 時間: 2025-3-25 06:09
