Is OGLE-2015-BLG-0051L b in the Habitable Zone?

The position of OGLE-2015-BLG-0051L b relative to the habitable zone of OGLE-2015-BLG-0051L cannot be precisely determined from the available orbital data.

Orbit and Year Length

OGLE-2015-BLG-0051L b orbits at an average distance of 0.730 AU — comparable to the inner Solar System.

How Was OGLE-2015-BLG-0051L b Discovered?

OGLE-2015-BLG-0051L b was discovered in 2016 using the microlensing method, with observations from OGLE.

Gravitational microlensing detects a planet when its host star passes in front of a more distant background star, and the planet's gravity adds a brief, telltale spike to the magnified starlight. It can find planets thousands of light-years away.

How Far Away Is OGLE-2015-BLG-0051L b?

OGLE-2015-BLG-0051L b is 26,744.8 light-years (8,200.0 parsecs) from Earth. Light arriving here tonight left the planet about 26,745 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 470,708,480 years to make the journey.
