Pluto is about 9 light hours from Earth.  The newest planet to be discovered is about 480 light years away.  CoRoT-7b (cool name!) is relatively small as exo-planets go, with a radius only about twice that of Earth.   But there’s no life there — almost certainly — because CoRoT-7b is only 1.6 million miles from its sun, meaning the planet’s sunward surface could be around 4,000 degrees Fahrenheit.  (We’re parked at a comfy 93 million miles from our sun.)

Because its orbit is so small, a “year” on CoRoT-7b lasts only 20 hours.

Here’s what it might look like.  And you can read more about it here.
