HV 2112
Red supergiant (Thorne-Zytkow candidate) · SMC V2156
Leading candidate Thorne-Zytkow object
A cool red giant in the Small Magellanic Cloud, and the long-standing candidate for a Thorne-Zytkow object: a theorised hybrid with a neutron star buried at its core. Later studies dispute that reading, so its true nature is still an open question.

It pours out about 63 thousand times the Sun’s light. Its light has been travelling 200,000 years to reach us, so you see HV 2112 as it was 200,000 years ago.
