Overview of the Solar System

The frost line for the Solar System lies between Mars and Jupiter. It marks a major divide in planet properties because outside of it, various kinds of frozen light molecules could accumulate on a forming planet as ices (for example, frozen water captures not only oxygen, but some hydrogen). These ices ran up the mass of the planet so it had a

About Where is the frost line in the solar system

About Where is the frost line in the solar system

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.

Different volatile compounds have different condensation temperatures at different partial pressures (thus different densities) in the protostar nebula, so their frost lines will differ. The actual temperature and distance for the.

The lower temperature in the nebula beyond the frost line makes many more solid grains available forintoand eventually . The frost line therefore.

• •.

The radial position of the condensation/evaporation front varies over time, as the nebula evolves.Occasionally, the term snow line is also used to represent the present distance at which water ice can be stable (even under direct sunlight). This.

• • • •The frost line in our solar system is a boundary that separates the areas where rocks and metals condense from where carbon and ice grains begin to condense. It is located at about 5 astronomical units (AU) from the Sun, which is just before the orbit of Jupiter123. Inside the frost line, surfaces exposed to the Sun are warm enough for water ice to melt or sublime readily, leaving exposed rock4.

6 FAQs about [Where is the frost line in the solar system]

What is frost line in astronomy?

Thus, in astronomy, the frost line (also referred to as snow line or ice line) is the distance from the protostar where the temperatures are not high enough for volatile molecule (such as water, ammonia, or methane) to change from their original solid state (ice particles) into a gaseous state.

Where is the frost line?

For the water molecule, the frost line is a little less than 5 astronomical units (AU), or around 700 million kilometers from our sun, at which point the average temperature falls below 170 K (−103 °C). At this location, between Mars and Jupiter, water in its gaseous state will condense back into ice.

Which planets are located inside the frost line?

The frost line therefore separates terrestrial planets from giant planet s in the Solar System. However, giant planets have been found inside the frost line around several other stars (so-called hot Jupiter s). They are thought to have formed outside the frost line, and later migrated inwards to their current positions.

Why do we know where each frost line occurs?

Understanding where each frost-line occurs allows us to extrapolate the composition of the objects formed throughout the solar system. For example, Europa lying within Jupiter’s orbit is mainly composed of rocks and water-ice as we are still too close from the Sun for other volatiles such as ammonia and methane to condense.

How far away is the frost line from the Sun?

The location of the "frost line" is also a matter of some debate, but current thinking holds that it is probably about 4 AU from the Sun. A great deal depends on how much solar radiation can penetrate deep into the outer parts of the primordial Solar Nebula.

Does the frost line determine a rocky or gas planet?

In the current solar system, the frost line is at about 5 AU, which is a bit closer than Jupiter, so currently all the rocky planets are inside the frost line, and all the gas giants are beyond the frost line. This would seem to imply that it’s the frost line that determines whether a rocky or gas planet will form.
