nomadd22 Posted May 12, 2005 Share Posted May 12, 2005 The sun won't go away. It will still be there and most of the planets will still be there. They'll be further away because the sun will have lost some mass. The Earth will probably be there, because it's orbit will have receded beyong the reach of the sun's red giant phase by then. Everything beyond the Earth will still be in orbit around the white dwarf sun that's left. Link to comment Share on other sites More sharing options...

How will the Earth survive that in the first place? Will we still recede from the Sun? Sorry if I sound like a total moron...but how will we start to move away from the sun at a pace that we won't get incinerated? Link to comment Share on other sites More sharing options...
Dave Posted May 12, 2005 Share Posted May 12, 2005 No, you're right. The Earth will almost certainly be swallowed up by the Sun when it expands. Jupiter outwards should survive, though. Link to comment Share on other sites More sharing options...
us.2u Posted May 13, 2005 Author Share Posted May 13, 2005 I have found a relative web-link which briefly explains the future...'When the sun becomes a super-nova' if anyone is interested I'll post the link willingly......us.2u Link to comment Share on other sites More sharing options...
Crash Posted May 13, 2005 Share Posted May 13, 2005 By survival of the planets you mean still mass's just moving around the sun? Hey Dave is there a chance that jupiter will ignite i remeber reading a year or so ago that jupiter isnt too far from being able to sustain itself as a sun, would this be possible in the event of our supernova?
