The study of Comet 238P/Read, which lurks in the main asteroid belt, could help reveal the source of Earth's water, a vital ingredient for life on our planet.
This artist’s concept of Comet 238P/Read shows the main belt comet sublimating—its water ice vaporizing as its orbit approaches the sun
The discovery of water vapor around Comet 238P/Read could significantly boost theories that water, a vital ingredient for life, was delivered to our planet from space by comets. But the study of the The team said that there are two possible reasons why Comet 238P/Read may be missing carbon dioxide. For one, the comet may have had carbon dioxide during its formation, which it has lost thanks to warming by the sun.
The alternative theory for the lack of carbon dioxide is that this main belt comet may have been formed in an area of the solar system devoid of the compound., H. Hsieh , A. Pagan )As its name suggests, the main asteroid belt is mainly home to rocky bodies like. Yet it does also host the occasional comet-like body like Comet 238P/Read. These cometary bodies can be identified by the fact that they periodically brighten as a halo of material or a coma surrounds them.
