K2-132 b
K2-132 b is a hot Jupiter orbiting K2-132 in the constellation Virgo. It lies about 1,989 light-years from Earth and was discovered in 2017 using the transit method.
How Big Is K2-132 b?
K2-132 b has a radius of 14.57 times that of Earth, or 1.30 times the radius of Jupiter. Its mass is 156 times that of Earth.
Is K2-132 b in the Habitable Zone?
The position of K2-132 b relative to the habitable zone of K2-132 cannot be precisely determined from the available orbital data.
Habitable zone of K2-132: 2.132–5.187 AU (conservative: 2.700–4.918 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on K2-132 b — one full orbit around K2-132 — lasts 9.18 Earth days, shorter than Mercury's 88-day year.
How Was K2-132 b Discovered?
K2-132 b was discovered in 2017 using the transit method, with observations from K2.
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 K2-132 b?
K2-132 b is 1,989.0 light-years (609.8 parsecs) from Earth. Light arriving here tonight left the planet about 1,989 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 35,006,400 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. K2-132 b scores 0.06, ranking #5,100 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About K2-132 b
Is K2-132 b habitable?
K2-132 b is not known to orbit within the habitable zone of K2-132, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is K2-132 b?
K2-132 b is about 1,989 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 35,006,400 years to get there.
How big is K2-132 b compared to Earth?
K2-132 b has 14.57 times the radius of Earth and about 156 times its mass.
How long is a year on K2-132 b?
One orbit around K2-132 takes 9.2 Earth days — short enough that 40 of its years would fit into one Earth year.
