PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar. The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond. [1] [2] PSR J1719-1438 b orbits so closely to its host star that its orbit would fit ...
High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune, while some planets in other planetary systems may be almost pure diamond. [2] Diamonds are also found in stars and may have been the first mineral ever to have formed.
While no scientist has stated to believe GJ 1214 b is an ocean planet, if GJ 1214 b is assumed to be an ocean planet, [22] i.e. the interior is assumed to be composed primarily of a water core surrounded by more water, proportions of the total mass consistent with the mass and radius are about 25% rock and 75% water, covered by a thick envelope ...
An alternative possibility is that 55 Cancri e is a solid planet made of carbon-rich material rather than the oxygen-rich material that makes up the terrestrial planets in the Solar System. [25] In this case, roughly a third of the planet's mass would be carbon, much of which may be in the form of diamond as a result of the temperatures and ...
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
Pulsars that were discovered before 1993 tend to retain their B names rather than use their J names, but all pulsars have a J name that provides more precise coordinates of its location in the sky. [5] On its discovery, the planet was designated PSR 1257+12 A and later PSR B1257+12 A. It was discovered before the convention that extrasolar ...
The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the researchers.
The planet's existence had first been suspected more than 30 years before by American astronomer Percival Lowell, whose study of the movements of the the orbits of planets, meteor showers and ...
