NASA have recently discovered through one of their special telescopes that there is another Earth-like habitable planet namely Kepler-186f, which was found revolving around a star located near Earth’s orbit. Kepler-186f is approximately 500 light-years from Earth in the Cygnus constellation.
Despite of the 40 million+ earth-sized planets revolving in the milky way, this is an exceptional one, since life is habitable in it. Other than Kepler-186f, there are 4 more planets discovered which revolve around varied stars in the Keple-186f system.
The nearby star to Kepler-186f has half the mass and size as our solar system’s Sun and recieves only one-third of the solar energy as compared to earth. The planet revolves around its star once in 130 days
“We know of just one planet where life exists – Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth,” said Elisa Quintana, research scientist at the SETI Institute at NASA’s Ames Research Center in Moffett Field, Calif., and lead author of the paper published today in the journal Science. “Finding a habitable zone planet comparable to Earth in size is a major step forward.”
The four companions planets are:
- Kepler-186b – Revolves in 4 days around sun
- Kepler-186c – Revolves in 7 days around sun
- Kepler-186d – Revolves in 13 days around sun
- Kepler-186e – Revolves in 22 days around sun
