HD 34445 f – a Neptune-like Exoplanet

HD 34445 f is an exoplanet that resembles Neptune and orbits a G-type star. Its semi-major axis is 1.54 astronomical units, whereas Earth’s is 1 astronomical unit. HD 34445 f has a mass of 37.842 times that of Earth. It has a mass of 37.9 Earths, takes 1.9 years to complete one orbit around its star, and is 1.543 AU away from it.

HD 34445 f is an exoplanet that orbits the star HD 34445, which is located approximately 151.7 light-years (46.5 pc) from our Solar System. Its discovery was made public in 2017. HD 34445 has an apparent magnitude of 7.3 and an absolute magnitude of 4.0. It is 1.1 times more massive and 1.4 times larger than our Sun.

The surface temperature is 5836 degrees Celsius, and the spectral type is G0V. The extrasolar planet HD 34445 f orbits the star HD 34445 at an orbital distance of 1.54 AU every 676.8 days in this planetary system.

It was discovered in 2017 and was announced. It was discovered in 2017-11 by the Multiple Observatories observatory using the radial velocity method. HD 34445 is a star in the equatorial constellation of Orion with multiple exoplanetary companions. It is a 7th magnitude star with an apparent visual magnitude of 7.31 that is too dim to be seen with the naked eye. The system is located at a distance of 150.5 light-years from the Sun based on parallax measurements, but is drifting closer with a high radial velocity of −79 km/s.

It is an extrasolar planet (exoplanet) that orbits the star HD 34445 in the Orion constellation. A planet that orbits a star other than the Sun is known as an exoplanet. According to the most recent parallax records, the star is 151.56 light-years away, or 46.47 parsecs from Earth. The planet’s orbital period, or year, is 676.8 days, or 1.85 Earth years. By the end of a full year, the Earth will have completed 0.54 orbits around its star.

HD 34445 f has a radius of 6.880 times that of Earth. HD 34445 f 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.
