Star system, 1,800 light-years
Kepler-452 and its one planet
Kepler-452 b is an exoplanet 1.63 times Earth's width, 1,800 light-years away, orbiting at the edge of its star's computed habitable zone.
Kepler-452 is a star of spectral type G2, 1,800 light-years from us, with one known planet.

measured The period, and where the table says so the width and the mass, by the method named in each section.
computed Anything marked computed: the size of an orbit where Kepler's third law corrects the table, the temperature of a bare ball at that distance, the starlight received, and the habitable zone.

Kepler-452 b
Kepler-452 b is an exoplanet 1.63 times Earth's width, 1,800 light-years away, orbiting at the edge of its star's computed habitable zone.
- Width
- 1.63 × Earth's measured
- Mass
- about 3.29 times Earth's estimated by the Archive from the planet's size, not measured
- One year
- 384.843 days measured
- Distance from its star
- 1.046 au from the Archive
- Temperature of a bare ball there
- 261 K computed, not measured
- Starlight, against Earth's
- 1.11 × computed
It was found as a small, regular dip in its star's light each time it crosses in front of it in 2015. Its orbit lies at the edge of the conservative habitable zone computed for its star.
