When Joe lived back on Earth, it felt like the years were flying by. Then he went to work in the mines on the iron planet, and discovered how wrong he'd been. One side of the small world enjoyed perpetual night, and in his heat-resistant spacesuit it was just cool enough to stand and drill into the ground. There was neither sunrise nor sunset to mark the passage of time, yet he knew the iron planet whirled around its star so fast that every time he lay down for his 8 Earth-hours of shut-eye, he woke up two years later.
If Joe the space miner existed, that would be his life on KOI 1843.03, a potential planet found by NASA's Kepler space telescope. This odd world appears to have the shortest known year, completing an orbit around its star in just 4 hours, 15 minutes.
Because it is so close to the star, one side of the planet most likely always faces the star and feels more of its gravitational pull, creating tidal forces that squish and stretch the tiny body. And to withstand the star's gravitational wrath, the planet must be made almost entirely of iron.
