Is there life on Gliese 1214b?
The calculations below confirm Gliese 1214b’s extremely high surface temperatures. At these high temperatures and high pressures, water cannot exist, on the surface, as a liquid. Therefore life, similar to life on Earth, cannot exist on Gliese 1214b’s surface.
Where is GJ 1214b located?
constellation Ophiuchus
But GJ 1214b, which is located 40 light-years from Earth in the constellation Ophiuchus (The Serpent Bearer), is something new altogether, researchers said. This so-called “super-Earth” is about 2.7 times Earth’s diameter and weighs nearly seven times as much as our home planet.

What is so scary about Gliese 1214 b?
Six times as massive as Earth, Gliese 1214 b is less than three times as wide, falling between the Earth and the solar system’s ice giants Uranus and Neptune in size. The high temperatures of the planet may affect the hydrogen and carbon chemistry, which could produce a haze in the atmosphere.
Is TrES 4b bigger than the Sun?
A planet enormous in size but small in density defies current theories of superheated giant planets. This computer-generated image of planet TrES-4 depicts its host star (right), bigger and hotter than the Sun and about 10 times larger than the planet.
How common are exoplanets?
So far, thousands of planets have been discovered by the Kepler mission. And more will be found by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission, which is observing the entire sky to locate planets orbiting the nearest and brightest stars. We now know that exoplanets are very common in the universe.
What planet is Waterworld?
As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. For that reason, scientists have nicknamed the planet “the waterworld”. It is a super-Earth, meaning it is larger than Earth but is significantly smaller (in mass and radius) than the gas giants of the Solar System.
How far is GJ1214b from Earth?
40 light yearsGliese 1214 b / Distance to Earth
Is GJ 1214 b an extrasolar planet?
Extrasolar planet. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 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.
How many light years away is GJ 1214b?
GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered.
What is the actual color of GJ 1214 b?
The actual color of GJ 1214 b is not yet known. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus.
How was the star GJ 1214 b discovered?
GJ 1214 b was first detected by the MEarth Project, which searches for the small drops in brightness that can occur when an orbiting planet briefly passes in front of its parent star. In early 2009, the astronomers running the project noticed that the star GJ 1214 appeared to show drops in brightness of that sort.
