HD 34445 d is an exoplanet that resembles Neptune and orbits a G-type star. HD 34445 d has a mass that is 30.846 times that of Earth. It has a mass of 30.7 Earths, takes 117.9 days to complete one orbit around its star, and is 0.4817 AU away from it. The radius is 6.070 times that of the Earth. HD 34445 d is an ice giant, a planet composed primarily of volatiles such as water, ammonia, and methane and surrounded by a dense hydrogen and helium atmosphere, similar to Uranus and Neptune in our solar system.
HD 34445 d is an extrasolar planet (exoplanet) that orbits the star HD 34445 in the constellation Orion. An exoplanet is a planet that orbits a star other than the Sun. According to the most recent parallax data, the star is 151.56 light-years or 46.47 parsecs from Earth. The planet’s orbital period, or year, is 117.87 days, or 0.32 Earth years. By the time the Earth has completed a full year, it will have completed 3.10 orbits around its star.
This planet has a minimum mass of two-thirds that of Jupiter and orbits the parent star at a distance of about two AU. This planet, however, orbits in a highly elliptical orbit. The planet’s distance from the star varies between 0.86 and 3.16 AU, but it spends its entire orbit within the star’s habitable zone. HD 34445 is a star in the equatorial constellation of Orion with multiple exoplanetary companions. This is a regular G-type main-sequence star with the stellar classification G0 V, indicating that it is a Sun-like star that generates energy through core hydrogen fusion. It is classified as a metal-rich star, with a much higher metallicity than the Sun.
HD 34445 d was discovered in 2017-11 by the Multiple Observatories observatory using the radial velocity method. It was discovered in 2017 and was announced. Its semi-major axis is 0.48 astronomical units, whereas Earth’s is 1 astronomical unit. The semi-major axis is the point in the orbit that is farthest from the star. The Earth orbits the Sun with a semi-major axis of just over 1 A.U. (1.00000011). The average distance between the Earth and the Sun is one A.U. The planet orbits its star at a closer distance to the Sun than Venus does.
