Jude Hi, we are Jude and Lucy. Our particular interest is not so much in the Sun itself, but in what comes from it - the so-called solar wind Lucy

The material blowing away from the Sun is what we call the ‘solar wind’...

 

No! there's no need to worry - even at that rate the Sun could keep on shinning for about another 300 thousand billion years!

 

(Don’t forget! A tonne is 1000 kg)
