OGLE-TR-182 b
OGLE-TR-182 b is a hot Jupiter orbiting OGLE-TR-182 in the constellation Carina. It lies about 8,160 light-years from Earth and was discovered in 2007 using the transit method.
How Big Is OGLE-TR-182 b?
OGLE-TR-182 b has a radius of 12.67 times that of Earth, or 1.13 times the radius of Jupiter. Its mass is 321 times that of Earth.
Is OGLE-TR-182 b in the Habitable Zone?
OGLE-TR-182 b orbits inside the inner edge of the habitable zone of OGLE-TR-182. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of OGLE-TR-182: 0.891–2.092 AU (conservative: 1.129–1.984 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on OGLE-TR-182 b — one full orbit around OGLE-TR-182 — lasts 3.98 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.051 AU — closer to its star than Mercury is to the Sun.
How Was OGLE-TR-182 b Discovered?
OGLE-TR-182 b was discovered in 2007 using the transit method, with observations from OGLE.
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 OGLE-TR-182 b?
OGLE-TR-182 b is 8,159.6 light-years (2,501.8 parsecs) from Earth. Light arriving here tonight left the planet about 8,160 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 143,608,960 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. OGLE-TR-182 b scores 0.07, ranking #4,892 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About OGLE-TR-182 b
Is OGLE-TR-182 b habitable?
No — OGLE-TR-182 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is OGLE-TR-182 b?
OGLE-TR-182 b is about 8,160 light-years from Earth in the constellation Carina. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 143,608,960 years to get there.
How big is OGLE-TR-182 b compared to Earth?
OGLE-TR-182 b has 12.67 times the radius of Earth and about 321 times its mass.
How long is a year on OGLE-TR-182 b?
One orbit around OGLE-TR-182 takes 4.0 Earth days — short enough that 92 of its years would fit into one Earth year.
