HD 108874 b – a gas giant Exoplanet

HD 108874 b is a gas giant exoplanet in the habitable zone of a G-type star. This gas behemoth was revealed in 2003. The orbit is in the habitable zone of the star. It has a mass of 1.42 Jupiters, takes 394.5 days to complete one orbit around its star, and is 1.04 AU away from it. Any moons around this planet are predicted to be carbon-rich, making them distinct from the Solar System’s silicate-rich entities. The planet may have a 4:1 orbital resonance with HD 108874 c. In 2002, it was announced that it had been discovered. This planet is named after the goddess of love and beauty, Hijo-okogei.

HD 108874 b is an extrasolar planet (exoplanet) that orbits the star HD 108874 in the Coma Berenices constellation. Exoplanets are planets that orbit stars other than the Sun. According to the most recent parallax records, the star is 204.24 light-years or 62.62 parsecs from Earth.

Discovery

The jovian planet HD 108874 b was discovered by a team led by Paul Butler, Geoffrey Marcy, Steven Vogt, and Debra Fischer from the United States. The discovery was made using a total of 20 radial velocity data acquired at the W. M. Keck Observatory in Hawaii between 1999 and 2002. Hijo-okogei, like the other cold planets, has a rocky core made up of heavier elements, although it lacks a well-defined ozone layer.

Characteristics

HD 108874 b is an exoplanet that orbits the star HD 108874, which is 193.3 light-years (59.3 pc) from our Solar System. Its discovery was made public in 2003. HD 108874 has an apparent magnitude of 8.8 and an absolute magnitude of 4.9.

It is 1.0 times more massive and 1.2 times larger than our Sun. The surface temperature is 5407 degrees Fahrenheit, and the spectral type is G5. The extrasolar planet HD 108874 b orbits the star HD 108874 every 395.4 days and has an orbital distance of 1.05 AU (157227362.1 km).

The planet’s orbital period, or year, is 395.4 days or 1.08 Earth years. By the time the Earth has finished a full year, it will have made 0.92 orbits around its star. The semi-major axis is the point in the orbit that is farthest from its star. The Earth revolves around the Sun with a semi-major axis of little over 1 A.U. 1 A.U. is the average distance between the Earth and the Sun. The planet orbits its star at a closer distance than Mars does to the Sun.
