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 smallest known extrasolar planet that is likely a "gas planet" is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope. [16] A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature. [17]
HD 73344 d is a Jovian planet, first identified in 27-year baseline radial velocity observations from multiple observatories, and later in Hipparcos-Gaia astrometric observations. Its mass, measured via astrometry, is two and a half times the mass of Jupiter. [10]

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.
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]
HD 1502 b revolves around its host star at a distance of 1.262 AU (188,800,000 km) with a period of little over one year in a near-circular orbit (i.e., with a low eccentricity), [3] similarly to planets in the Solar System. [11] It is a super-Jupiter planet with a minimum mass of 2.75 M J and a predicted radius of 1.183 R J. [3]
