Is MOA-2011-BLG-028L b in the Habitable Zone?

The position of MOA-2011-BLG-028L b relative to the habitable zone of MOA-2011-BLG-028L cannot be precisely determined from the available orbital data.

Orbit and Year Length

MOA-2011-BLG-028L b orbits at an average distance of 4.140 AU.

How Was MOA-2011-BLG-028L b Discovered?

MOA-2011-BLG-028L b was discovered in 2016 using the microlensing method, with observations from MOA.

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 MOA-2011-BLG-028L b?

MOA-2011-BLG-028L b is 24,070.3 light-years (7,380.0 parsecs) from Earth. Light arriving here tonight left the planet about 24,070 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 423,637,280 years to make the journey.
