Kepler-22 is a Sun-like star in the northern constellation of Cygnus, the swan, that is orbited by at least 1 planet found to be unequivocally within the star's habitable zone.

2024年10月24日 · Kepler-22 b is a super Earth exoplanet that orbits a G-type star. Its mass is 9.1 Earths, it takes 289.9 days to complete one orbit of its star, and is 0.812 AU from its star.

2020年10月25日 · Kepler-22 is a Sun-like yellow main sequence star located 638 light years from Earth. It hosts Kepler-22b, a planet that orbits in the star's habitable zone.

Kepler-22b (also known by its Kepler Object of Interest designation KOI-087.01) is an exoplanet orbiting within the habitable zone of the Sun-like star Kepler-22. It is located about 640 light-years (200 parsecs) from Earth in the constellation of Cygnus.

2011年12月5日 · It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone – the region around a star where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our sun.

Kepler-22b was the first exoplanet ever discovered lying inside its parent star’s habitable zone. It was discovered by the now-retired Kepler Space Telescope and, at the time, was an incredible discovery. That was back in 2011, but the exoplanet still represents one of our best chances of discovering live elsewhere in the Universe.

2011年12月5日 · The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun. The planet is about 2.4 times the radius of Earth.

2023年7月23日 · The star is called Kepler-22, and it is located about 640 light-years away from Earth in the constellation of Cygnus, the swan. That means that the light we see from this star …

Star Kepler-22 is a main sequence star that fuses hydrogen atoms into helium. It is approximately 100 % of the size of Sun and temperature on its surface is around 5518 K (5245 °C), which is about 96 % of Sun's temperature.
