Iota Geminorum (ι Geminorum, ι Gem) is a solitary [9] fourth-magnitude star in the constellation Gemini. In the sky, it forms an isosceles triangle with Castor and Pollux, and is located less than a degree from the 5th magnitude stars 64 and 65 Geminorum. [10]
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] [a] 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]

NGC 2266 is an open cluster [5] of stars in the constellation of Gemini. It was discovered by German-British astronomer William Herschel on 7 December 1785. [6] This is a relatively dim cluster with an integrated visual magnitude of 9.5 and an angular size of 5.0′. The stellar members can be readily resolved with an amateur telescope. [3]
