Is OGLE-2019-BLG-0304L b in the Habitable Zone?
The position of OGLE-2019-BLG-0304L b relative to the habitable zone of OGLE-2019-BLG-0304L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2019-BLG-0304L b orbits at an average distance of 1.230 AU.
How Was OGLE-2019-BLG-0304L b Discovered?
OGLE-2019-BLG-0304L b was discovered in 2021 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-2019-BLG-0304L b?
OGLE-2019-BLG-0304L b is 22,765.7 light-years (6,980.0 parsecs) from Earth. Light arriving here tonight left the planet about 22,766 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 400,676,320 years to make the journey.
