Planets Around TRAPPIST-1 Probably Rich in Water
Astronomers have discovered something interesting about the planets around one of our closest stars...
… they may have lots, and lots, of water!
In 2017, seven planets were found orbiting a very cool dwarf star — TRAPPIST-1.
Now, astronomers have found that some of these planets probably hold about 250 times more water than all of Earth’s oceans!
The 4th of the seven planets, called TRAPPIST-1e, is the most similar to Earth, in terms of size, density, and radiation of all known exoplanets.
Whether the water is in steamy clouds, oceans or ice...
… these seven planets, only 40 light-years away, may have the potential to be homes for life.
