What is the snow line?

The snow line also known as the frost or ice line is a line that runs in between Mars and Jupiter. It is also roughly located in the middle of the asteroid belt. This line separates inner planets from outer planets and solid planets from ice or gas planets. All the planets that are closer to the sun starting from Mars are considered as inner planets and all the planets after Mars starting from Jupiter are outer planets. This line is the point where everything freezes which makes planets like Jupiter, Saturn, Uranus, and Neptune way colder than Mars, Earth, Venus and Mercury.



How was it formed?

The most accurate theory about the formation of the snow line in the solar system is the Solar Nebula theory. This is also one of the theory about how the solar system came to be.  Solar Nebula theory: Billions of years ago, the solar system was a giant rotating interstellar cloud of dust and gas. Then the center of the cloud collapsed on it self creating the sun and the other materials turned into spinning disks. As the center of the cloud turned into the sun, the solar wind was created as well. The solar wind was really strong and it blew all the particles in all direction. Some of those particles got blew so far away that it crossed the snow line and turned into ice and gas planets and some that weren’t blew that far away just stayed solid, rocky planets. So the snow line is something that separates the ice and gas planets from the rocky, solid planets

The snow line is a really important part

of the solar system.
