Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
Due to this, Kepler-452b is receiving roughly 10% more stellar radiation than the Earth does today. If Kepler-452b is a rocky planet, it might be subject to a runaway greenhouse effect . However, because of its mass (estimated to be about 5 M E ), it may be able to prevent succumbing to the runaway greenhouse for a limited amount of time (at ...
Kepler-452b lies 1400 light-years from Earth, in the Cygnus constellation. [45] Its radius of about 1.6 R ⊕ [46] places it right on the boundary separating telluric planets from mini-Neptunes established by the team of Courtney Dressing, a researcher at the Harvard-Smithsonian Center for Astrophysics (CfA).

Astronomers have searched for years for rocky planets beyond our solar system with an atmosphere - a trait considered essential for any possibility of harboring life. Researchers said on Wednesday ...
Kepler-69c has gone through a similar process; though initially estimated to be potentially habitable, [69] it was quickly realized that the planet is more likely to be similar to Venus, [70] and is thus no longer considered habitable. [1]
Comparison of the HZ position of Earth-radius planet Kepler-186f and the Solar System (17 April 2014) While larger than Kepler 186f, Kepler-452b's orbit and star are more similar to Earth's. Recent discoveries have uncovered planets that are thought to be similar in size or mass to Earth. "Earth-sized" ranges are typically defined by mass.
"The location of this FRB so far outside its host galaxy raises questions as to how such energetic events can occur in regions where no new stars are forming.” Further study of fast radio bursts ...
Kepler-442b [1] [4] [5] (also known by its Kepler object of interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star [6] Kepler-442, about 1,196 light-years (367 pc) from Earth in the constellation of Lyra.
