OGLE-2013-BLG-1721L b
OGLE-2013-BLG-1721L b is a cold gas giant orbiting OGLE-2013-BLG-1721L in the constellation Scorpius. It lies about 20,548 light-years from Earth and was discovered in 2017 using the microlensing method.
Is OGLE-2013-BLG-1721L b in the Habitable Zone?
The position of OGLE-2013-BLG-1721L b relative to the habitable zone of OGLE-2013-BLG-1721L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2013-BLG-1721L b orbits at an average distance of 2.600 AU.
How Was OGLE-2013-BLG-1721L b Discovered?
OGLE-2013-BLG-1721L b was discovered in 2017 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-2013-BLG-1721L b?
OGLE-2013-BLG-1721L b is 20,547.8 light-years (6,300.0 parsecs) from Earth. Light arriving here tonight left the planet about 20,548 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 361,641,280 years to make the journey.
