Our solar system is about 4 billion years old with Sun as our only star, 8 planets – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune – and 3 dwarf planets which are Ceres, Pluto and Eris.
Jupiter’s radius is about 69,000 km or 43,000 miles and its surface width is almost equal to 122 Earths! It’s sometimes called a failed star because it mainly contains hydrogen and helium gas, major components of a star.
The yellow dwarf star stands in the middle of the orbits, becoming the center of life to our Earth. It’s the surface area is 12,000 Earths and is made of 73% hydrogen and 25% helium.
