OGLE-TR-111 b
OGLE-TR-111 b is a hot Jupiter orbiting OGLE-TR-111 in the constellation Carina. It lies about 3,484 light-years from Earth and was discovered in 2004 using the transit method.
How Big Is OGLE-TR-111 b?
OGLE-TR-111 b has a radius of 11.42 times that of Earth, or 1.02 times the radius of Jupiter.
Is OGLE-TR-111 b in the Habitable Zone?
The position of OGLE-TR-111 b relative to the habitable zone of OGLE-TR-111 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on OGLE-TR-111 b — one full orbit around OGLE-TR-111 — lasts 4.01 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.047 AU — closer to its star than Mercury is to the Sun.
How Was OGLE-TR-111 b Discovered?
OGLE-TR-111 b was discovered in 2004 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-111 b?
OGLE-TR-111 b is 3,484.4 light-years (1,068.3 parsecs) from Earth. Light arriving here tonight left the planet about 3,484 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 61,325,440 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-111 b scores 0.08, ranking #4,637 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About OGLE-TR-111 b
Is OGLE-TR-111 b habitable?
OGLE-TR-111 b is not known to orbit within the habitable zone of OGLE-TR-111, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is OGLE-TR-111 b?
OGLE-TR-111 b is about 3,484 light-years from Earth in the constellation Carina. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 61,325,440 years to get there.
How big is OGLE-TR-111 b compared to Earth?
OGLE-TR-111 b has 11.42 times the radius of Earth.
How long is a year on OGLE-TR-111 b?
One orbit around OGLE-TR-111 takes 4.0 Earth days — short enough that 91 of its years would fit into one Earth year.
