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 ( volatiles ), rather than rock or other solid matter, but massive solid planets can also exist.
HD 175541 b, also named Kavian, is a jovian planet located approximately 424 light-years away [3] in the constellation of Serpens, orbiting the star HD 175541.This planet was discovered in April 2007.
Gliese 504 b (or 59 Virginis b) is a jovian planet or a brown dwarf orbiting the solar analog 59 Virginis (Gliese 504), [note 1] discovered by direct imaging using HiCIAO instrument and AO188 adaptive optics system on the Subaru Telescope of Mauna Kea Observatory, Hawaii by Kuzuhara et al. [4]
The Jupiter mass, also called Jovian mass, is the unit of mass equal to the total mass of the planet Jupiter. This value may refer to the mass of the planet alone, or the mass of the entire Jovian system to include the moons of Jupiter. Jupiter is by far the most massive planet in the Solar System. It is approximately 2.5 times as massive as ...
These planets would appear as featureless azure-blue globes because of Rayleigh scattering and absorption by methane in their atmospheres, appearing like Jovian-mass versions of Uranus and Neptune. Because of the lack of a reflective cloud layer, the Bond albedo is low, around 0.12 for a class-III planet around a Sun-like star.
An eccentric Jupiter is a Jovian planet that orbits its star in an eccentric orbit. [1] Eccentric Jupiters may disqualify a planetary system from having Earth-like planets (though not always from having habitable exomoons ) in it, because a massive gas giant with an eccentric orbit may eject all Earth mass exoplanets from the habitable zone ...

On Friday, February 9, 2007, a 3.32 years period jovian planet was found by using the wobble method by O'Toole and colleagues in Australia. [7] It has minimum mass 53% greater than Jupiter and orbits with a 41% eccentricity. The maximum stable period for a hypothetical inner planet is 322.1 days. [2]
