First planet discovered to have a retrograde orbit [131] and first to have quartz (crystalline silica, SiO 2) in its clouds. [132] Has an exteremely low density of 0.08 g/cm 3, [133] the lowest of any exoplanet when it was discovered, and was possibly the largest exoplanet at the time of discovery, with a radius of 1.92 R J. [134] KELT-19 Ab: 1 ...
TrES-4b is an extrasolar planet, and one of the largest exoplanets ever found. It was discovered in 2006, and announced in 2007, by the Trans-Atlantic Exoplanet Survey, using the transit method. It is approximately 1,400 light-years (430 pc) away orbiting the star GSC 02620-00648, in the constellation Hercules. [1]
The term gas giant was coined in 1952 by the science fiction writer James Blish [6] and was originally used to refer to all giant planets.It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form. [7]
The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune — are much denser. ... It's the second-lightest exoplanet found so far based on its dimensions and mass, according to ...
It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth , and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm ), with an orbital period of 11.86 years .
A super-Jupiter is a gas giant exoplanet that is more massive than the planet Jupiter. For example, companions at the planet–brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae. [1] By 2011 there were 180 known super-Jupiters, some hot, some cold. [2]
A giant anaconda species captured recently in the Amazon of Ecuador by a team of scientists is the largest to ever be documented, USA TODAY previously reported, and now, there are images showing ...
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low-boiling point materials (), rather than rock or other solid matter, but massive solid planets can also exist.
