HD 27245, also known as HR 1335 or rarely 25 H. Camelopardalis is a solitary red-hued

light years[1] away from it the Solar System and is drifting further away with a heliocentric radial velocity of 25.2 km/s.[6] At its current distance, HD 27245's brightness is diminished by 0.36 magnitudes due to extinction from interstellar dust.[16] It has an absolute magnitude of −0.27.[7]

HD 27245 is an aging

luminosity of the Sun[10] from its enlarged photosphere at an effective temperature of 4,033 K.[12] HD 27245's iron abundance is 129% that of the Sun's,[8]
making it metal enriched.

HD 27245 is a suspected variable star with an amplitude of 0.05 magnitudes.[5] Its variability was first observed in 1930 by Joel Stebbins.[17] However, Eggen (1967) instead lists it as an ordinary M-type giant and used the object for comparison.[18] In 1978-9, HD 28245 was again listed as a variable star but did not provide further insight.[19] As of 2017, the star has not been confirmed to be variable.[5]
