Tool for simulating the impact of an asteroid or comet with planets and moons in the Solar System. The Sun is responsible for the comet's activity because it heats up the comet's nucleus to sublimate its ice into gas, which outgasses and lifts up dust from the comet's surface to form its coma. Initial speculation as to the cause of this acceleration pointed to the comet-like outgassing, [25] whereby volatile substances inside the object evaporate as the Sun heats its surface. E.
