The Solar System is made up of all the planets that orbit our Sun and also consists of moons, comets, asteroids, minor planets, and dust and gas. In a Solar System, every object near it orbits or revolves around the Sun. This is on account of fact that Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it.Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun.
For millennia, astronomers have actually adhered to points of light that appeared to move among the stars. The old Greeks specified these earths, indicating “wanderers.” Mercury, Venus, Mars, Jupiter and Saturn were known in classical times, as well as the creation of the telescope added the Asteroid Belt, Uranus, Neptune, Pluto and a number of these globes’ moons. The dawn of the space age saw loads of probes released to explore our system, an adventure that continues today. The discovery of Eris started a breakout of new discoveries of dwarf earths.
Astronomers are currently hunting for an additional world in our planetary system, a true nine world, after proof of its existence was unveiled on Jan. 20, 2016. The supposed “Planet Nine,” as researchers are calling it, is about 10 times the mass of Earth and also 5,000 times the mass of Pluto.
