I’ve been learning lots about the solar system today! This one I definitely needed to look up…
The sun is 4 and a half billion years old!
I guess the sun has technically been in the solar system the whole of its life because ‘solar system’ literally means the system around the sun. I think the planets etc. formed around the sun once the sun had come into existence but perhaps one of the other scientists will know more…
Yes, as Emma says, the Sun is as old as the solar system (our solar system) because the presence of the Sun defines. What I don’t know though, and would be interested to know, is whether all the planets formed at the same time or whether that was a stepwise process. Anyone else to shed some light on this?
