OGLE-2016-BLG-1195Lb is an

extrasolar planet located about 22,000 light-years from Earth, in the galactic bulge, orbiting the 0.57±0.06 M☉[6] star OGLE-2016-BLG-1195L, discovered in 2017.[4][5][3] The planet was detected using gravitational microlensing techniques managed by the Korea Astronomy and Space Science Institute and the Spitzer Space Telescope
. Initially, it was believed the planet has a mass similar to Earth and is located about the same distance from its host star as the Earth is from the Sun,[4] although it was expected to be much colder.[7][8][4]

In 2023, the planetary mass estimate was significantly increased to 9.91±1.61 ME, resulting in it likely being a Neptune-like ice giant planet.[6]

In popular culture

The planet has been referred to as Hoth due to its resemblance (before 2023 parameters update) to the planet with the same name from the Star Wars franchise.[8] A similar exoplanet, OGLE-2005-BLG-390Lb, has also been compared to Hoth, by NASA in this instance.[9]
