HOW BIG IS OUR SOLAR SYSTEM :
Our Solar System is our local neighbourhood in space and is dominated by the Sun. The Sun is huge – about one million Earths could fit inside it, and it makes up about 99.8 percent of our Solar System’s mass. Eight major planets circle the Sun. These are divided into two groups:
● The inner Solar System – the small rocky planets (Mercury, Venus, Earth and Mars).
● The outer Solar System – the massive gas giants beyond the asteroid belt (Jupiter, Saturn, Uranus and Neptune).
