'''OGLE-2016-BLG-1195Lb''' is an extrasolar planet located about 22,000 [[Astronomy:Light-year|light-year]]s from Earth, in the galactic bulge, orbiting the 0.57{{±|0.06}} {{Solar_mass}}<ref name=Vandorou2023/> [[Astronomy:Star|star]] OGLE-2016-BLG-1195L, discovered in 2017.<ref name="NASA-20170426" /><ref name="JPL-20170426" /><ref name="EXO-2017" /> The planet was detected using [[Physics:Gravitational microlensing|gravitational microlensing]] techniques managed by the [[Organization:Korea Astronomy and Space Science Institute|Korea Astronomy and Space Science Institute]] and the [[Astronomy:Spitzer Space Telescope|Spitzer Space Telescope]]. 
Initially, it was believed the planet has a [[Physics:Mass|mass]] similar to [[Astronomy:Earth|Earth]] and is located about the same distance from its host star as the Earth is from the Sun,<ref name="NASA-20170426" /> although it was expected to be much colder.<ref>{{Cite web | url=https://www.sciencedaily.com/releases/2017/04/170426122437.htm |title = 'Iceball' planet discovered through microlensing}}</ref><ref name="CNN-20170426" /><ref name="NASA-20170426" />

In 2023, the planetary mass estimate was significantly increased to 9.91{{±|1.61}} {{Earth_mass}}, resulting in it likely being a Neptune-like [[Astronomy:Ice giant|ice giant]] planet.<ref name=Vandorou2023>{{citation|arxiv=2302.01168|year=2023|title=OGLE-2016-BLG-1195Lb: A SUB-NEPTUNE BEYOND THE SNOW LINE OF AN M-DWARF CONFIRMED BY KECK AO |last1=Vandorou |first1=Aikaterini |last2=Dang |first2=Lisa |last3=Bennett |first3=David P. |last4=Koshimoto |first4=Naoki |last5=Terry |first5=Sean K. |last6=Beaulieu |first6=Jean-Phillipe |last7=Alard |first7=Christophe |last8=Bhattacharya |first8=Aparna |last9=Blackman |first9=Joshua W. |last10=Bouchoutrouch-Ku |first10=Tarik |last11=Cole |first11=Andrew A. |last12=Cowan |first12=Nicolas B. |last13=Marquette |first13=Jean-Baptiste |last14=Ranc |first14=Clément |last15=Rektsini |first15=Natalia }}</ref>

==In popular culture==
The planet has been referred to as Hoth due to its resemblance (before 2023 parameters update) to [[Earth:Hoth|the planet with the same name]] from the ''Star Wars'' franchise.<ref name="CNN-20170426" /> A similar exoplanet, [[Astronomy:OGLE-2005-BLG-390Lb|OGLE-2005-BLG-390Lb]], has also been compared to Hoth, by [[Organization:NASA|NASA]] in this instance.<ref name="NASA-20151215" />
