HD 63433 (TOI-1726, V377 Geminorum) is a G-type main sequence star located 73 light-years from Earth in the zodiacal constellation Gemini,^[9]^{[note 1]} visually close to the star Pollux.^[7] It has nearly the same radius and mass of the Sun, hence being classified as a Sun-like star.^[9] However, it is much younger than the Sun, less than one tenth as old with an age of about 400 million years.^[9]^[a] With an apparent magnitude of 6.9, it is not visible to the naked eye, but can be seen with a small telescope^[12] or binoculars.^[13] Based on its kinematic, rotational and lithium abundance properties, it is part of the Ursa Major Moving Group.^[9] There are three exoplanets orbiting it, one is classified as an Earth-sized planet, while the two others are mini-Neptunes.^[4]
