HD 2039 b is a planet that orbits the star HD 2039. It is a gas giant exoplanet that revolves around a G-type star. It is nearly five times the mass of Jupiter and has a highly eccentric orbit. It has a mass of 6.29 Jupiters, takes 3.1 years to complete one orbit of its star, and is located 2.2 AU away from it. In 2002, it was announced that it had been discovered.
Exoplanets are planets that orbit stars other than the Sun. According to the most recent parallax records, the star is 334.53 light-years or 102.56 parsecs from Earth. The mass and radius are calculated in relation to Jupiter. Jupiters denotes that it has ten times the mass of Jupiter and is equivalent to Mass.
HD 2039 b is an extrasolar planet orbiting the star HD 2039. It is a gas giant exoplanet that orbits a G-type star.
The Anglo-Australian Planet Search team discovered a planet orbiting the star in a highly eccentric orbit in 2002. It has a minimum mass that is more than four times that of Jupiter and an orbital period that is more than three years. The planet orbits its star at a distance of about two AU; the Earth, on the other hand, orbits the Sun at a distance of one AU. The discovery of HD 2039 b was announced quietly; no press release was issued by the observatory that discovered the planet, and no formal announcement of the planet’s existence was made. The object was the 100th confirmed exoplanet by the scientific community.
HD 2039 is a stable G-type star, which means it emits white light similar to that of the Sun. HD 2039 has a radius that is roughly 40% larger than that of the Sun. While HD 2039 has a temperature of 5935 K, the Sun’s surface temperature is nearly 200 kelvins lower at 5778 K. Astrophysicists have been drawn to HD 2039 because it is unusually metal-rich.
Distance and visibility
The magnitude of the star as seen from Earth is 9; this means that the body is not visible to the naked eye but can be seen with a telescope. HD 2039 is about 280 light-years away from the Sun, which is about the same distance as the second brightest star in the night sky, Canopus.
