Solar System is a planetary system of the Sun and the objects that orbit it. The name comes from the Sun's latin name, Sol. This system formed around 4.6 billion years ago when a dense region of a molecular cloud collapsed into the Sun and its protoplanetary disc. The fusion of hydrogen into helium inside the Sun's core releases energy, which is primarily emitted through its outer photosphere. This creates a decreasing temperature gradient across the system. The Sun is 99.86% of the System's mass
Solar System consists of one star (Sun), eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune) and nine dwarf planets (Ceres, Orcus, Pluto, Haumea, Quaoar, Makemake, Gonggong, Eris and Sedna) and 1 482 264 smaller objects (like asteroids or meteors).
There are also 729 natural satellites orbiting six planets and seven dwarf planets, and also some few smaller bodies. They range from planet-sized (Ganymede) to tiny moonlets.
There are two belts of minor objects in the Solar System, the Asteroid belt and the Kuiper belt. The Asteroid belt is located between Mars and Jupiter and is home thousands of asteroids, which are remaining leftovers from the formation of the Solar System that took place around 4.603 billion years ago.
The inner terrestrial planets Mercury, Venus, Earth, and Mars have a rocky surface composed of rocky and metallic material. They lack a ring system, have very few natural satellites, and other relatively much smaller than their gaseous counterparts. The outer gaseous planets, Jupiter, Saturn, Uranus, and Neptune, have a gaseous or liquid surface composed of hydrogen and helium. The gaseous planets are also classified into two terms: the Gas Giants and the ⁸. The Asteroid belt and the Kuiper belt are inhabited by hundreds of dwarf and minor planets. Most of the dwarf planets ( Pluto Is Not One Of Those Planets) are massive enough to be rounded by their own gravity, but are two small in size to be referred to as normal planets.
Formation
80 million years before the Sun formed, two neutron stars collided and caused a mass ejection of various materials into outer space, creating a large interstellar cloud of gas known as the Solar Nebula.
Around 4.603 billion years ago, a shockwave from a nearby supernova that triggered the nebula into an accretion state, where the cloud flattens into a rotating disk of materials. At the center of the accredited nebula, 99.86% of all the materials gathered together to form the Sun. The remaining materials gathered together into a clump of rocky materials that would be the core of Jupiter. The other remaining materials created the rest of the planets and the belts.
Location
The Solar System is located in the Local Interstellar Cloud, which is located in the Local Bubble, which is located in the Orion-Cygnus Arm of the Milky Way Galaxy.
The Solar System is 27,000 light years away from the Milky Way Galaxy's center and goes on an orbital period around the galaxy every 240 million years.
