Kepler-483 b
Kepler-483 b is a sub-Neptune orbiting Kepler-483 in the constellation Lyra. It lies about 2,806 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-483 b?
Kepler-483 b has a radius of 3.21 times that of Earth.
Is Kepler-483 b in the Habitable Zone?
The position of Kepler-483 b relative to the habitable zone of Kepler-483 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-483: 1.286–2.992 AU (conservative: 1.628–2.836 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-483 b — one full orbit around Kepler-483 — lasts 30.2 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-483 b Discovered?
Kepler-483 b was discovered in 2016 using the transit method, with observations from Kepler.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is Kepler-483 b?
Kepler-483 b is 2,806.1 light-years (860.4 parsecs) from Earth. Light arriving here tonight left the planet about 2,806 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 49,387,360 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. Kepler-483 b scores 0.22, ranking #3,641 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-483 b
Is Kepler-483 b habitable?
Kepler-483 b is not known to orbit within the habitable zone of Kepler-483, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is Kepler-483 b?
Kepler-483 b is about 2,806 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 49,387,360 years to get there.
How big is Kepler-483 b compared to Earth?
Kepler-483 b has 3.21 times the radius of Earth.
How long is a year on Kepler-483 b?
One orbit around Kepler-483 takes 30.2 Earth days — short enough that 12 of its years would fit into one Earth year.
