A point at which ice tends to not melt even when exposed to direct sunlight. A significant boundary in our Solar System of which affected the characteristics of our now known planets.

Explanation:

Those planets formed in the outer regions of the Frost Line contained more ice and gas because of the low temperatures and pressure present in that area.
Those planets formed or that 'were' forming inside the inner dwellings of the Frost Line for example, Mars on wards to Mercury are made out of more rocky and metallic materials. This is because of the more exposure to the sun and less condensation of liquid water. Although, it is still possible to have liquid water condense into ice when presented with the correct pressure and or temperature, e.g. Earth.
