The OGLE-2017-BLG-0173L system contains 1 exoplanet. It is located 15345.64 light years away from the solar system.
|Mass||0.4 solar masses|
|Radius||0.32 solar radiae|
|Stellar Metallicity||- decimal exponent|
|Age||- billion years|
At 3.272 Earth masses, OGLE-2017-BLG-0173L b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. With a mass below 5 Earth masses, and a semi-major axis of 3.913 astronomical units, which is outside the habitable zone of OGLE-2017-BLG-0173L, OGLE-2017-BLG-0173L b is likely an icy world.
