Kepler 22B Ocean Planet. It was discovered by nasa's kepler space telescope in 2011. Though kepler 22b is not the first such planet to be detected in recent years, it is the first one still, that hasn't completely quashed mission optimism about the planet as kepler team member natalie batalha speculates that, it's not beyond the realm of possibility that life could exist in such an ocean.
Kepler 22b orbits around a star like our sun, a bit smaller and colder, every 290 days; It has an orbital period of 290 days. & apj., 745, 120 paper arxiv.
G type, main sequence system name:
It is the first planet that. At 2.4 times earth's because of its radical tilt, its north and south poles would be alternately bathed in sunlight and darkness, for half a year each, as the planet circled its star. It has an orbital period of 290 days. Natalie batalha, one of the scientists on the kepler space telescope project, has speculated, if it is mostly ocean with a small rocky core, it's not.
