 Sun is said to be 4.603 billions of years old with constantly hot plasma in its core providing energy to all biotic ans abiotic lifes.ita radius is 696340 km with a distance from Earth of 149.6 billion km . 
Temperature of sun has been calculated as 5,778K . Its being so hot that no life can survive on its surface.
