OGLE-2016-BLG-1195Lb
OGLE-2016-BLG-1195Lb is an extrasolar planet located about 22,000 light-years from Earth, in the galactic bulge, orbiting the 0.57 star OGLE-2016-BLG-1195L, discovered in 2017. 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, although it was expected to be much colder. In 2023, the planetary mass estimate was significantly increased to 9.91, resulting in it likely being a Neptune-like ice giant planet. In popular culture The planet has been referred to as Hoth due to its resemblance (before 2023 parameters update) to Hoth, the planet with the same name from the ''Star Wars'' franchise. A similar exoplanet, OGLE-2005-BLG-390Lb, has also been compared to Hoth, by NASA in this instance. See also * Gliese 581c * Gliese 5 ...

OGLE-2005-BLG-390Lb
OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA) is a super-Earth exoplanet orbiting OGLE-2005-BLG-390L, a star from Earth near the center of the Milky Way, making it one of the most distant planets known. On January 25, 2006, Probing Lensing Anomalies NETwork/ Robotic Telescope Network (PLANET/Robonet), Optical Gravitational Lensing Experiment (OGLE), and Microlensing Observations in Astrophysics (MOA) made a joint announcement of the discovery. The planet does not appear to meet conditions presumed necessary to support life. Characteristics Mass, radius and temperature The planet is estimated to be about five times Earth's mass (5.5 ). Some astronomers have speculated that it may have a rocky core like Earth, with a thin atmosphere. Its distance from the star, and the star's relatively low temperature, means that the planet's likely surface temperature is around , making it one of the coldest known. If it is a rocky world, this temperature would make it likely that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
