Earth-like planet found
- rms 18y agoThe new one is outside the habitable zone though. The older one from the system, Gliese D, is believed to be in the habitable zone and may be a water world.
- pavel_lishin 18y ago"Earth-like" is pushing it. It's not ridiculously bigger than the Earth, and it's probably made of rocks. It is an important discovery because it shows that we can discover planets that are approximately Earth sized, but put down your home-made space-suits, people.
- russell 18y agoAs others said, It's too close to the star to be habitable, but the good news is that it is 1.9 times the mass of the earth, meaning that the chances of finding earth size planets in a habitable zone are getting very good. M class stars are not good candidates for habitable planets, because they would probably be tidally locked and the stars are less stable. G and K stars are better, but the planets are harder to find, because the stars are so much larger and brighter.
