How long would earth be warm if...

[tony873004]

If you want a realistic scenerio, rather than a vanishing Sun, a rogue planet or brown dwarf could pass through the solar system. It's gravity could eject Earth from the solar system. It's highly unlikely, but more likely than the Sun simply vanishing.

 

I imagine ocean currents would be able to keep some islands habitable for months.

Months? I rather doubt that.
