This is only an estimate, using the star's spectral type and mass. Kepler-438 b is a super Earth exoplanet that orbits a M-type star. Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone. Both exist in the constellation Lyra. Kepler 442b is confirmed in close proximity to the earth-shaped exoplanet. It is very unclear to see this planet with a naked eye from Earth.Kepler 442b is circuits with its host star with a radius of 0.4 times the Earth's orbit with 112.3 days of rotation. It has a 60% chance of being rocky. Habitable zone Kepler-442 b … Its mass is 1.46 Earths, it takes 35.2 days to complete one orbit of its star, and is 0.166 AU from its star. Kepler 442b. Going to this index, Earth has a rating of 0.829, but Kepler-442b has a rating of 0.836. It was previously known as KOI-4742.01. List of Extrasolar Planets orbiting Kepler 442. A superhabitable planet would have shallow oceans. Its discovery was announced in 2015. Kepler-442 b is a super Earth exoplanet that orbits a K-type star. Kepler-62e and Kepler-442b are like siblings. Kepler 452b is considered the most Earth like planet yet discovered due to its size, location in its system and the type of star it orbits. The surface gravity on this planet, however, is supposed to be only 30% stronger than Earth. Kepler-442b completes one orbit every 112 days and gets about two-thirds as much light as Earth. It is not known if Kepler-452b is a rocky planet but based on its small radius, Kepler-452b is likely to be rocky. Kepler-452b is most likely not tidally locked and has a circular orbit. If applicable, the Mass and Radius is measured in Jupiters. Both orbit K class stars that could give them a high potential for sustaining plant life. Potential habitability. Kepler 452b orbits its star at a similar distance that the Earth orbits the sun. Kepler-442b is a confirmed Earth-sized extrasolar planet orbiting the orange dwarf Kepler-442, 1115 light years away. Its host star, Kepler-452, is about 20% more luminous than the Sun (L = 1.2 L ☉).. Eccentricity is measured as a decimal from 0 to 1, the closer to zero, the more circular the orbit is. A year on Kepler 452b is only 21 days longer than a year on Earth. Its discovery was announced in 2015. The equations of Selsis, Kasting et al are used to draw the inner and outer boundaries. Its mass is 2.36 Earths, it takes 112.3 days to complete one orbit of its star, and is 0.409 AU from its star. Kepler-442b features an orbit of 112 days and has a diameter that's about one-third larger than Earth. Kepler-452b is sometimes called 'Earth 2.0', ... For instance, Kepler-452b takes 385 Earth days to complete its orbit around its star, which is only a bit longer than one Earth year. The star that Kepler 452b orbits is very similar to our sun.
