The sun

This sun is the largest star the solar system however there are many stars like it in the wider universe the earth just the right distance from the sun but our planets is not too hot or too cold. The light from the sun takes 8 minutes to reach earth . And gives lifes to plants. Astronauts will never be able to land on the sun. It reaches 50000 5000 degrees celsius 100 times hotter than humans can stan. The sheer size of the sun means that the gravitational pull forces all the planets in our solar system to orbit around it billion 50000 years ago the sun has been producing heat and light for a very long time .
