The solar system is enormous, with a diameter of at least 100 Astronomical Units 15 trillion km. Our Solar System is thought to be over 4.6 billion years old, according to several experts.
The enormous gravitational force of the sun holds it together, keeping planets and asteroids in orbit around it. The earth is the densest of all the planets in our solar system. he nine known planets and their moons, as well as smaller objects orbiting the sun known as comets, asteroids, and meteoroids, make up the solar system’s largest and most important components.
Due to their higher boiling points, only metals and silicates could exist in solid form in the warm inner Solar System close to the Sun, and these would eventually form the rocky planets of Mercury, Venus, Earth, and Mars. Because metallic elements only comprised a very small fraction of the solar nebula, the terrestrial planets could not grow very large.
The giant planets Jupiter, Saturn, Uranus, and Neptune formed further out, beyond the frost line, the point between the orbits of Mars and Jupiter where material is cool enough for volatile icy compounds to remain solid. The ices that formed these planets were more plentiful than the metals and silicates.
Objects in the Solar System :
Asteroids are rocky and metallic objects that orbit the Sun but aren’t large enough to be termed planets. They are called Minor Planets. The majority of the asteroids in our solar system orbit the Sun between Mars and Jupiter’s orbits. The “asteroid belt” is a term used to describe this region.
the Sun is also orbited by smaller rocks and dust particles. These particles of rock or dust make their way into the atmosphere.
They come into contact with a lot of friction as they pass, which causes them to heat up and burn out. Meteors are little shards of rock or dust that burn. The majority of meteors burn up before they reach Earth. Some are so massive that a piece of it falls to Earth as a meteorite. The planets and other large objects in orbit around the Sun lie near the plane of Earth’s orbit, known as the ecliptic. Smaller icy objects such as comets frequently orbit at significantly greater angles to this plane. Most of the planets in the Solar System have secondary systems of their own, being orbited by natural satellites called moons. Many of the largest natural satellites are in synchronous rotation, with one face permanently turned toward their parent. The four giant planets have planetary rings, thin bands of tiny particles that orbit them in unison.
