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 ...

2024年10月24日 · Kepler-452 b is a super Earth exoplanet that orbits a G-type star. Its mass is 3.29 Earths, it takes 384.8 days to complete one orbit of its star, and is 1.046 AU from its star. Its discovery was announced in 2015.

2015年7月23日 · The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun.

2015年7月24日 · The exoplanet Kepler-452b is a planet very much like and the closest cousin or twin to our planet yet found. See all about planet Kepler-452b in our full infographic.

2025年1月2日 · Kepler-452b, the first approximately Earth-sized planet to be found in a Sun-like star’s habitable zone—the orbital region where an Earth-like planet could possess liquid water on its surface and thus possibly support life.

2024年10月5日 · Kepler-452b is a potentially habitable exoplanet discovered in 2015. The planet orbits a Sun-like star every 385 days within its habitable zone. Kepler-452b measures 60% larger than Earth and could potentially support liquid water on its surface.

2015年7月23日 · The new discovery, Kepler-452b, fires the planet hunter's imagination because it is the most similar to the Earth-sun system found yet: a planet at the right temperature within the habitable zone, and only about one-and-a-half times the diameter of Earth, circling a star very much like our own sun.

2015年7月22日 · NASA's Kepler mission has confirmed Kepler-452b as the first near-Earth-size planet in the “habitable zone” around a sun-like star.

2015年7月23日 · NASA's Kepler space telescope has spotted the most Earth-like alien planet yet discovered — a world called Kepler-452b that's just slightly bigger than our own and orbits a sunlike star at...

The star hosts one unconfirmed exoplanet, Kepler-452b, discovered in July 2015 by the Kepler spacecraft. This planet is mostly known for its characteristics similar to Earth, most notably its size, orbit and stellar flux.
