because of asteroid hits, for example — and the fog comes pouring into the classroom.

Unlike the hundreds of
thousands of asteroids in the main belt of our solar system, which move cleanly along their orbits, active asteroids were discovered several years ago mimicking comets with their tails formed by calm, long lasting ice sublimation.
Not shown in the above illustrations are the numerous smaller bodies that inhabit the solar system: the satellites of the planets; the large
number of asteroids (small rocky bodies) orbiting the Sun, mostly between Mars and Jupiter but also elsewhere; the comets (small icy bodies) which come and go from the inner parts of the solar system in highly elongated orbits and at random orientations to the ecliptic; and the many small icy bodies beyond Neptune in the Kuiper Belt.
The round - body definition provides planetary scientists with a useful guide to selecting objects in the solar system that could shed light on processes here on Earth, says Sykes, who is part of the science team for NASA's Dawn mission to dwarf planet Ceres and Vesta, the two largest
members of the asteroid belt between Mars and Jupiter.
Whether their results can also apply to bright asteroids or dark asteroids found in other
regions of the asteroid belt remains to be seen.
