QY Puppis is aK-type supergiant star in the constellation ofPuppis. With a radius of 515 R☉, it is on the smaller end of thelargest known stars.[7] Avariable star, itsapparent magnitude varies from 6.24 to 6.71, making it very faintly visible to thenaked eye under ideal observing conditions, when it is at its brightest.

Properties

[edit]

In 1981, Armando Arellano Ferro published an article stating that the star, then called HD 63302, might be a variable star.[9] It was given itsvariable star designation, QY Puppis, in 1985.[10] QY Puppis has been classified in theGeneral Catalogue of Variable Stars as asemiregular variable star of type SRD.[3] QY Puppis has a temperature of 4,251 K,[8] and has expanded to a radius of 515 R☉.[7] It is approximately 60 million years old, with a mass of 6.2 M☉.[6]
