The speed and distance at which planets orbit their respective blazing stars can determine each planet’s fate—whether the planet remains a longstanding part of its solar system or evaporates into the universe’s dark graveyard more quickly.
In their quest to learn more about far-away planets beyond our own solar system, astronomers discovered that a medium-sized planet roughly the size of Neptune, dubbed GJ 3470b, is evaporating at a rate 100 times faster than a previously discovered planet of similar size, GJ 436b.
