Help find strange comet-like asteroids that could reveal secrets of the solar system

Comets are comets, and asteroids are asteroids…except when they aren’t. Some asteroids appear to be active, and form the familiar comas, and even tails, of their comet cousins. Astronomers know only a few dozen examples of these active asteroids, but they suspect there are many more—and you can join the hunt. The asteroids you spot can reveal secrets about the history of the solar system.

asteroids Relatively simple. The remaining parts of the stillborn rocky planets, they are rich in carbon, iron and other heavier elements. They are basically just big balls of rock.
