HD 164922 d is a super Earth exoplanet in the habitable zone of a G-type star. It has a mass of four Earths, takes 12.5 days to complete one orbit of its star, and is 0.103 AU away from it. It was discovered in 2020 and was announced.
HD 164922 d is an exoplanet that orbits the star HD 164922, which is located approximately 72.2 light-years (22.1 pc) from our Solar System. Its discovery was made public in 2020. This planet orbits the star at 2.11 AU and has a low eccentricity of 0.05. Almost exactly ten years later, in 2016, another exoplanet was discovered orbiting farther in from the star, though it was less massive than the first. This planet has a minimum mass of nearly 13 times that of Earth, meaning it is possibly a Neptune-like planet.
HD 164922 has an apparent magnitude of 7.0 and an absolute magnitude of 5.3. It is 0.9 times more massive and 1.0 times larger than our Sun. The surface temperature is 5293 degrees Fahrenheit, and the spectral type is G9V. The extrasolar planet HD 164922 d orbits the star HD 164922 every 12.5 days at an orbital distance of 0.12 AU in this planetary system.
HD 164922 is a G-type main-sequence star with a mass 87 percent that of the Sun and a radius 99 percent that of the Sun. It is 13.4 billion years old and has a temperature of 5293 K. The Sun, on the other hand, is approximately 4.6 billion years old and has a temperature of 5778 K. At an age of 13.4 billion years, it will soon evolve away from the main sequence and expand to become a red giant. It is one of the oldest known stars in the Universe and one of the most ancient multi-planetary systems known in the Milky Way.
HD 164922 d is an exoplanet that orbits the star HD 164922 in the Hercules constellation. A planet that orbits a star other than the Sun is known as an exoplanet. According to the most recent parallax data, the star is 72.14 light years or 22.12 parsecs from Earth.
The planet’s orbital period, or year, is 12.458 days or 0.03 Earth Years. By the end of a year, the Earth will have completed 29.30 orbits around its star. The semi-major axis is the distance between the planet and its star in its orbit. The Earth revolves around the Sun with a semi-major axis of slightly more than 1 A.U. 1 A.U. is the average distance of the Earth from the Sun. The planet orbits its star at a closer distance than Mercury does to the Sun.
