HV 11417 is a candidate Thorne–Żytkow object in the Small Magellanic Cloud, put forward in a paper by Emma Beasor and collaborators. The paper also claims that another candidate for the Thorne–Żytkow object, HV 2112, was not a Thorne–Żytkow object because it seemingly lacked any distinguishing quality which would indicate that classification. HV 11417 has since been identified as a likely foreground halo star. As of Gaia's 3rd data release the star has been measured to have a negative measured parallax suggesting a distance of more than 103,000 light-years (32,000 pc) at the 3-sigma level, and a proper motion consistent with Small Magellanic Cloud stars in its region of the galaxy.
