The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars.

The Solar system is a group of planets, asteroids, comets, and other things that orbit around the Sun. Think about it as our local neighborhood. Mars, Venus, Jupiter, and the other planets are our close neighbors. The Sun is at the center of the Solar system.

The solar system consists of our sun, which is a star, and all that its gravity affects. The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There are also dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids of all shapes and sizes.

It consists of our sun and eight main planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There are also moons, dwarf planets, asteroids, comets, rocks and dust.

The solar system was formed about 4.7 billion years ago. It probably started as a loose cloud of gas and dust. Scientists think that a force called gravity pulled parts of the cloud together into clumps. The largest clump was squeezed together so tightly that it got very hot.
