Kepler 78b is an Earth-sized exoplanet not too far from us--only about 700 light-years away. But don't bother getting your hopes up about settling there, because Kepler 78b is one of the most aggressively unpleasant planets ever discovered (a competitive category, to be sure): its surface is covered with seas of boiling lava and it completes its orbit around its star in a whiplash-inducing 8.5 hours.
Researchers at MIT discovered the exoplanet while indulging an experiment: how close can a planet be to its star? Kepler 78b is about 40 times closer to its star than Mercury is to our sun; in fact, Kepler 78b's orbit is only three times larger than the circumference of the star it's orbiting! (Earth's orbit is more than 215 times larger than the circumference of our sun, for comparison.)
To find the planet, the team pored over research from NASA's Kepler telescope, analyzing the tiny dips in light visible from stars, indicating that a planet might be passing in front. This particular star is younger than ours, and rotating twice as fast, which may have some influence on how Kepler 78b is able to exist. Not that Kepler 78b is a pleasant place; the researchers believe it's made of some highly dense material, but that its surface is about 5,000° F and covered in oceans of boiling lava. Oh, and it completes its year in about as long as you complete one (relatively light!) day of work. It's one of the fastest orbits ever detected.
Imagine standing on a planet that zoos around its sun this fast. When yoy watch the night sky...assuming a planet this close to its star would have anything trembling a night sky :-p...and watching the stars zip by! Be a pretty cool sight.
Wow...ignore my typos..I wrote that last comment from my phone...zoos = zooms....yoy = you....and trembling = resembling...thank you auto correct...

are you kidding me, we wont make there cause we cant even travel to Mars, let alone 700 light-years...dumbest shit ever said....
I'm surprised PopSci even wrote on this story. I mean, FoxNews covered the story a few days ago. So it can't be true......right?
If a planet is that close to it's sun, could it's dark side be habitable?
