My Actifit Report Card: September 21 20259

It is called Goldilocks, the zone where there is enough heat in a planetary system, where a planet can receive enough heat from its star to have liquid water on the surface, the problem of the goldilocks zone is when a planet receives enough heat to have water on the surface. but where does the water come from? because water, water ice cannot be maintained in space in that orbit, in that area of ​​golden rituals.

The Earth when it was originally forming was a magma ocean, that is, too hot due to the impacts and everything that was colliding with it to form, to maintain liquid water on the surface, whether ice or water and when the surface solidified, it can only take 3 million years, the planet was dry because it was in an area where there was no water ice, so that water ice had to come from beyond what is the asteroid belt and Jupiter.

The snow line, which is what the area where blocks of water ice can already exist in space is technically called, would be in the outer area of ​​the asteroid belt, because on Jupiter we already found huge moons that are covered with water ice, at that time perhaps that water line was closer to Mars, but the Earth was not in the warm area.
