What planets can people live on. You might be happy to learn that 8 8 billion earth sized planets have been discovered so far.
What It Would Look Like If Other Planets Were As Close As The Moon Planets Science And Nature Astronomy Science
This is a list of potentially habitable exoplanets the list is mostly based on estimates of habitability by the habitable exoplanets catalog hec and data from the nasa exoplanet archive the hec is maintained by the planetary habitability laboratory at the university of puerto rico at arecibo.
Other planets that look like earth. Before kepler 186f kepler 62f was the exoplanet known to be most similar to earth. Over 30 of those planets in ou. However with continuing discoveries other earth comparisons remained.
Kepler 22b lies 600 light years away. Lead researcher michael gillon said. As such mars in fiction portrayed the red planet as similar to earth but with a desert like landscape.
However a study in 2018 by mullally et al. Kepler 452b is an exoplanet orbiting the sun like star kepler 452 about 1 402 light years from earth in the constellation cygnus. Moreover its mass of 5 earth masses increases the possibility that the planet is a mini neptune instead of a.
Notably this planet has a mass that is similar to earth s. It was identified by the kepler space telescope and its discovery was announced by nasa on 23 july 2015. Surface planetary habitability is thought to require orbiting at the right distance from the host.
Like the new discovery kepler 62f is a super earth about 40 percent larger than our home planet. Images and data from the mariner 1965 and viking space probes 1975 1980 however revealed the planet as a barren cratered world. The seven wonders of trappist 1 are the first earth size planets that have been found orbiting this kind of star.
In fact it s thought that the planet formally known as ross 128 b could be similar to earth in terms of both its size and surface. Implied that statistically kepler 452b has not been proven to exist and must still be considered a candidate. It is also the best target yet for studying.
It was the first kepler planet found in the habitable zone of its parent star but the world is considerably larger than earth about 2 4 times our planet s.
