Physical characteristics [1] | |
Mass | 0.0485+0.0302 −0.0223 MJ |
KMT-2022-BLG-0440L b is a Neptune-like exoplanet, located 11,415 light years away in the constellation of Sagittarius. It was discovered in 2023. [2]
KMT-2002-BLG-0440L b was discovered by the
gravitational microlensing method. This exoplanet's mass is 0.0485+0.302
−0.0223
MJ or 15.4
Earth mass. The exoplanet has a planet radius of 0.361 times that of Jupiter and its orbital radius is 1.9
AU.
[2]
KMT-2022-BLG-0440L b has a longer orbital period than Earth. The exoplanet has an orbital period of 3.6 years, just like KIC 5951458 b. KMT-2022-BLG-0440L b has a semi-major axis of 1.9±0.7 AU.
The host star of KMT-2022-BLG-0440L b is KMT-2022-BLG-0440L.
The star type is currently unknown and is not visible with the
unaided eye from Earth. The
star has a
stellar mass of 0.5300 and has 0.53+31
−26
M☉.
