HD 47536
star
HD 47536 is a single star in the southern constellation of Canis Major. It has an orange hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.25. The star is located at a distance of approximately 408 light years from the Sun based on parallax. It is drifting further away with a radial velocity of 80 km/s.
This is an aging, metal-poor giant star with a stellar classification of K1 III. It is about 9.3 billion years old with 94% of the mass of the Sun. Having exhausted the supply of hydrogen at its core, the star cooled and expanded to 23 times the Sun's radius. The star is spinning slowly, taking 1.71 years to complete its sidereal rotation. It is radiating 177 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,384 K. As of 2015, at least one planet is known to orbit this star.
Planetary system
A planetary companion to this star, HD 47536 b, was discovered in 2003 by a team led by J. Setiawan. A second planet candidate, HD 47536 c, was proposed in 2007, but was not confirmed by any subsequent study.
This brief starts where responsible research should: with the source description of “HD 47536” as star. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as star. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q1563353. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 2003 and 2007.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
