Formation and evolution of the Solar System

OverviewFutureHistoryFormationSubsequent evolutionMoonsGalactic interactionChronology

Astronomers estimate that the current state of the Solar System will not change drastically until the Sun has fused almost all the hydrogen fuel in its core into helium, beginning its evolution from the main sequence of the Hertzsprung–Russell diagram and into its red-giant phase. The Solar System will continue to evolve until then. Eventually, the Sun will likely expand sufficiently to overwhelm the i

Which object(s) formed last in our solar system? the Sun

Nov 12, 2023· Next, planetesimals began to form. Lastly, the inner planets, including Earth, formed. Explanation: The Sun formed first in our solar system. It is the main source of heat and light, and its formation marks the beginning of our solar system. The solar nebula formed next, which was a rotating cloud of gas and dust.

How did planetesimals form in the Solar System?

The inner Solar System, the region of the Solar System inside 4 AU, was too warm for volatile molecules like water and methane to condense, so the planetesimals that formed there could only form from compounds with high melting points, such as metals (like iron, nickel, and aluminium) and rocky silicates.

How Do Planets Form?

The dust around a star is critical to forming celestial objects around it. Saturn, Uranus and Neptune, the gas giants of our solar system, are thought to have formed. Jupiter and Saturn are thought to have formed first and quickly within

What enables the presence of life in the Solar System?

Besides solar energy, the primary characteristic of the Solar System enabling the presence of life is the heliosphere and planetary magnetic fields (for those planets that have them). These magnetic fields partially shield the Solar System from high-energy interstellar particles called cosmic rays.

Why do solid objects in the outer Solar System contain more volatiles?

Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid, without significant rates of sublimation. [ 20 ]

All the foregoing constraints are consistent with the general idea, introduced in Other Worlds: An Introduction to the Solar System, that the solar system formed 4.5 billion years ago out of a rotating cloud of vapor and dust—which we call the solar nebula —with an initial composition similar to that of the Sun today. As the solar nebula collapsed under its

Where does the Solar System end?

If you base it on where the planet''s end you would say the edge is Neptune and the Kuiper Belt. If based on the edge of the sun''s magnetic field then it ends at the heliosphere. But if you judge it by the endpoint of the sun''s gravitational influence, the solar system ends at the Oort Cloud, according to NASA.
