Object info
Our Sun is a regular main-sequence class G2 star. It is the largest object in our solar system and contains more than 99.8% of all mass present in our solar system.
At present our Sun's mass consists of about 70% hydrogen, 28% helium and some other elements. This amount slowly changes over time as hydrogen is converted to helium in the core of our Sun.The average remaining life-span of our Sun is estimated to be about 4.5 billion years after which it will slowly expand into a red giant star which will eventually collapse and explode.
This will probably create a nice planetary nebula, but unfortunately we won't be around anymore to take a picture of it !
