In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the minimum distance from the central protostar of a solar nebula where the temperature is low enough for volatile compounds such as water, ammonia, methane, carbon dioxide and carbon monoxide to condense into solid grains, which will allow their accretion into planetesimals.
Planetesimals beyond the frost line accumulated up to 4 M E within about 3 million years. [38] Today, the four giant planets comprise just under 99% of all the mass orbiting the Sun. [b] Theorists believe it is no accident that Jupiter lies just beyond the frost line. Because the frost line accumulated large amounts of water via evaporation ...

According to the solar nebular disk model, rocky planets form in the inner part of the protoplanetary disk, within the frost line, where the temperature is high enough to prevent condensation of water ice and other substances into grains. [64] This results in coagulation of purely rocky grains and later in the formation of rocky planetesimals.
The boundary in the Solar System beyond which those volatile substances could coalesce is known as the frost line, and it lies at roughly five times the Earth's distance from the Sun. [5] Orbits Animations of the Solar System's inner planets orbiting.
Jennifer Grey looked back on how a sex scene with Patrick Swayze — that was ultimately cut from 1984’s Red Dawn — was derailed by him being drunk, and her "smoking a lot of weed" at the time ...
In a Facebook post Tuesday night, the George County Sheriff's Office urged the public to be cautious. "He will be desperate and very very dangerous. Call your family and alert them. Send messages ...
It’s very fortunate that the home of Junie B has smooth hardwood floors, as she’d have a far harder time pulling this move on uneven tile or even carpeted floors like I have.
