GJ 1214 b (sometimes Gliese 1214 b, formally named Enaiposha) is an exoplanet that orbits the star GJ 1214, and was discovered in December 2009. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet.
GJ 1214 b is a Neptune-like exoplanet that orbits a M-type star. Its mass is 8.41 Earths, it takes 1.6 days to complete one orbit of its star, and is 0.01505 AU from its star. Its discovery was announced in 2009.
May 10, 2023 · This artist’s concept depicts the planet GJ 1214 b, a “mini-Neptune” with what is likely a steamy, hazy atmosphere. A new study based on observations by NASA’s Webb telescope provides insight into this type of planet, the most common in the galaxy.
May 10, 2023 · It’s the closest look yet at the mysterious world, a “mini-Neptune” that was largely impenetrable to previous observations. And while the planet, called GJ 1214 b, is too hot to harbor liquid-water oceans, water in vaporized form still could be a major part of its atmosphere.
May 10, 2023 · GJ 1214 b, a warm sub-Neptune-sized exoplanet roughly 48 light-years from Earth, is one of the most studied exoplanets in the galaxy. Previous spectroscopic observations indicate that the planet is shrouded in aerosols (clouds or haze), which made it impossible to determine the composition of gases that make up its thick atmosphere before Webb.
Feb 21, 2012 · GJ 1214b, shown in this artist's conception, is a super-Earth orbiting a red-dwarf star 40 light-years from Earth. Observations suggest that its atmosphere is mostly water. David A. Aguilar / CfA. One exoplanet that's attracted a lot of attention since its discovery in 2009 is GJ 1214b.
May 10, 2023 · The light GJ 1214 b receives from its central star serves as a probe. Any interactions of the planet with the starlight will then show up in fluctuating proportions of the planet’s radiation. The measurement data also indicate the concrete composition of the atmosphere.
