Astronomers Find Evidence Of A Rocky Exoplanet That's 26 Percent Water

•, By Francie Diep
Hello? Is it you I'm looking for? Astronomers have found evidence of a small, rocky planet or asteroid whose mass is up to 26 percent water. Even Earth is only 0.023 percent water, by mass. This is the first time a rocky body with water has been found outside of our own solar system.

"Our results demonstrate that there was definitely potential for habitable planets in this exoplanetary system," Jay Farihi, an astronomer at Cambridge University and the lead author on the research, said in a statement.

But things aren't looking good for the watery planet today. It's now just a bunch of debris orbiting its star, a white dwarf called GD 61. Farihi and his team think that in the past, something—possibly a bigger rocky planet—knocked the watery planet close to GD 61, whose gravity then pulled the little guy apart.
