The Sun and planetary system formed about 4.6 billion years ago from a giant molecular cloud of gas and dust. A disturbance, possibly from a nearby supernova, triggered the collapse of this cloud, leading to the formation of a rotating protoplanetary disk. The Sun formed at the center as material accumulated, while particles in the surrounding disk coalesced to form planets, moons, and other solar system bodies through processes of accretion and gravitational attraction.

What is the closest solar system is proxima?

The term "solar system" is derived from the word Sol, which is the Latin name for the Sun - our sun. So there is, really, only one solar system. All others are called planetary systems. The nearest of star with a planetary system is Proxima Centauri, at a distance of 1.3 parsecs.


What is Planetary System?

A planetary system is a collection of celestial bodies that orbit a star, including planets, moons, asteroids, comets, and other objects. The most well-known example is our solar system, which consists of the Sun and its orbiting planets, such as Earth, Mars, and Jupiter. Planetary systems can vary widely in composition and structure, with some having multiple stars or a diverse range of planetary types. They form through the process of accretion from a protoplanetary disk of gas and dust around a newly formed star.


Why is the earth part of the solar system?

When Earth was created, it was sucked into the Sun's gravitational field like the other 7 planets. That is why it revolves around the Sun.
