Kepler-452b is an Earth-like planet which is located approximately 1400 light-years away from Earth in Cygnus constellation. It was first identified by NASA’s veteran telescope, Kepler. This planet is nearly four times massive and about 60% larger than Earth in diameter. Its surface gravity is found to be nearly twice the surface gravity of Earth (18.63 m/s²). Consequently, Kepler-452b is named as Super-Earth.
Kepler-452b is made of rocks and metals whereas the planet seems to have chances of habitual life in the future. Proclaimed by NASA, travelling to Kepler-452b seems to be an impossible task due to the shortage of fuel to travel to this humongous distance. It is also predicted that in future maybe this is possible. There is substantial opportunity for life to arise in Kepler-452b.
Kepler-452b may have active volcanoes due to its high mass and density. The Super-Earth circles its star between the orbital distances of Venus and Earth. Its star is 1.5 billion years older than our sun and it is hotter and brighter than our Sun. Its star is 10% larger than the sun. The planet has an orbital period around 385 days (only 5% longer than an Earth year).
It is misunderstood that due to increased energy output of Kepler-452b’s sun, it might currently be causing it to heat up and lose its oceans. Such a scenario likely won’t occur on Kepler-452b for another 500 million years or so, assuming estimates for the planet’s size and the star’s age are accurate. The stronger gravity of larger planets allows them to hang on to their surface water for long periods of time in such situations than smaller worlds can. and as per scientists it indeed very rare to discover exoplanets like Kepler 452-b, the Super-Earth.
