This disintegrating planet is an endangered species. Boiling away due to its close proximity to its star, it is quickly disappearing at least in cosmic terms. While planets like Earth last billions of years, this one could be gone in just 200 million. And although the star it orbits is smaller and cooler than our sun, the planets orbit is so tight that its yearone complete orbitis only 16 hours long. The planets surface temperature? Around 3,300 degrees Fahrenheit.
