蓝。
The Inner Solar System
This animation shows the motion of objects in the inner region of the solar
system over a two-year period at 10-day intervals. The sun is the yellow
symbol at the center of each frame. The orbits of the planets Mercury, Venus
, Earth and Mars are shown in light blue, with the current locations of each
planet being shown by large crossed circles. Main-belt minor planets are
shown as green circles, Near-Earth asteroids as red circles. Comets are
shown as blue squares (filled for numbered periodic comets, outline for
other comets).

Computer simulations suggest that the original asteroid belt may have
contained mass equivalent to the Earth.[37] Primarily because of
gravitational perturbations, most of the material was ejected from the belt
within about a million years of formation, leaving behind less than 0.1% of
the original mass.[29]
那就是说现在还有大约千分之一个地球的质量
