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.
The Line of the Sun, titled La Línea del Sol in the Spanish translation, is a 1989 novel written by Puerto Rican-American author Judith Ortiz Cofer. The story spans three decades, beginning in the late 1930s and ending in the 1960s. [1] The novel is Ortiz Cofer's main work of prose, and its publication helped broaden her readership. [2]
An artist's illustration giving a simple overview of the main regions of a protoplanetary disk, delineated by the soot and frost line, which for example has been observed around the star V883 Orionis. [15] The nebular hypothesis of solar system formation describes how protoplanetary disks are thought to evolve into planetary systems.
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 ...
If the frost line of our Solar system is 2.7 AE, how can both Earth and Mars, which are further inside, have large amounts of water ice?--Roentgenium111 17:51, 12 September 2010 (UTC) Asteroid and comets impacts could have easily brought water-ice with them. Keep in mind that Earth is a dry planet that is only 1.5% water by weight.
Hauntingly beautiful and deeply enigmatic, “Neptune Frost” has enjoyed perhaps the most coveted festival run of 2021. Blending science fiction, dance and allegorical elements, the striking ...
In geology, the frost line is the level down to which the soil will normally freeze each winter. By an analogy, the term is introduced in other areas. Frost line (astrophysics), a particular distance in the solar nebula from the central protosun where it is cool enough for hydrogen compounds such as water, ammonia, and methane to condense into solid ice grains.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
