NASA has found a strange alien planet that sits on our planet outside the sun.
The world is cool and small – scientists find two characteristics.
The small planet called HD 21749b, TESS, is the third planet discovered by NASA's planet-hunting telescope. He has a long orbit around a star, carrying 36 days calmly.
Despite this proximity, it's pretty cool around 300 degrees Fahrenheit.
In this way, scientists could be a very important way to find out about terrific and humble worlds.

29/30 Jupiter's Great Red Spot by Voyager I
30/30 The Chandra Observatory sees the heart in the dark
"This is the best planet we know about this bright star," says Diana Dragomir, MIT's Astrophysics and Space Research Kavli Institute, head of the new discovery.
"We know a lot about the atmospheric heat of the planet, but it is very difficult to find smaller orbits that are farther away from the star, and thus to reflect on these cooler non-planets. But here we were lucky, and we caught this and now we can learn more details."
Even though scientists have found it small, the world is very huge on our side: three times our size and 23 times massive. This puts it in the "sub-Neptune" and the first planet that TESS has found will be roughly a ground.
But it's hard to look like our planet. They are probably gas like Neptune or Uranus, although they are much more intense than the atmosphere.
"This planet would not be gas like Neptune or Uranus gas, that is, hydrogen and the most amazing one," says Dragomir. "The Earth's density is water density, or a thick atmosphere."
