Our Solar System!!!:)

Hello my fellow bloggers today i've been asked to write a blog post about our solar system, so I thought I would tell you a little bit about it.
I will tell you about our Sun tehen about the solar system.
The sun is a star in the middle of our solar system and is at the age of 4.6 billion year old. The sun is a yellow dwarf andnis almost a perfect sphere, the surface temperature of 5500*c.

The solar system, the solar is the planetary system around the sun. Eight planets or it the sun, four smaller planets known as terrstrial planets.

The four outer planets known as 'Gas Giants' are much bigger than the terrestrial planets up untill 2006 there was 9 planets however Pluto the very outer planetis now classed as a dwarf planet.

At the centre of the solar system is anstar known as the Sun. All the planets obit the sun. On Earth it takes 365 days for the Earth to orbit the sun, so the earth orbits the sun once a year some planets have much longer years than ours and some have much shorter years.
