description Kepler-452b Overview
Kepler-452b is an exoplanet orbiting a G-type star approximately 1,400 light-years from Earth. It’s notable as a super-Earth within its star's habitable zone, suggesting potential for liquid water on its surface. Scientists study this planet to understand the characteristics of potentially habitable worlds beyond our solar system and assess the diversity of planetary systems in the galaxy.
help Kepler-452b FAQ
Why is Kepler-452b often referred to as 'Earth's Cousin'?
Kepler-452b is dubbed 'Earth's Cousin' because it is the first near-Earth-size planet found orbiting in the habitable zone of a G2-type star, just like our Sun. It has a radius roughly 1.6 times that of Earth.
How long does it take for Kepler-452b to orbit its host star?
Kepler-452b takes approximately 385 Earth days to complete one full orbit around its star. This orbital period is remarkably similar to Earth's 365-day year.
How far away is Kepler-452b from our solar system?
The exoplanet is located about 1,400 light-years away from Earth in the constellation Cygnus. With our current maximum spacecraft speeds, traveling to this distant planet would take millions of years.
Does Kepler-452b actually have liquid water on its surface?
While Kepler-452b sits in the habitable zone where liquid water is theoretically possible, scientists do not yet know if it actually has water. Confirming its atmospheric composition or surface features requires more advanced telescopes than the now-retired Kepler mission.
