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.
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.
The radii of these objects range over three orders of magnitude, from planetary-mass objects like dwarf planets and some moons to the planets and the Sun. This list does not include small Solar System bodies , but it does include a sample of possible planetary-mass objects whose shapes have yet to be determined.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.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.
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 ...
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 ...
Direct calculations indicate that, in a typical protoplanetary disk, the formation time of a giant planet via pebble accretion is comparable to the formation times resulting from planetesimal accretion. [31] The formation of terrestrial planets differs from that of giant gas planets, also called Jovian planets.
Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io . [ 1 ]
