WebDec 15, 2024 · Light from a distant star is bent and focused by gravity as a planet passes between the star and Earth. Gravitational Microlensing The first Earth-size planet discovered around a near solar twin, the discovery of Kepler-452b brings us closer than ever to finding an Earth-like planet. WebKepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as much as Earth's, though calculations of mass for exoplanets are only rough estimates. [9] If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.
