HD 46375 is an 8th-magnitude K-type subgiant star located approximately 109 light-years away in the constellation of Monoceros. This star resembles an orange dwarf but has a larger radius and luminosity, indicating that fusion reactions in its core are starting to cease and the star is on its way becoming a red giant. The spectral type of the star is K1 IV. Its advanced evolutionary stage shows that it is considerably older than the Sun.

This star has sometimes been classified as a member of the NGC 2244 star cluster in the Rosette Nebula, but in reality it just happens to lie in the foreground. The distance to the cluster is much greater, about 4500 light-years.

In 2000, a low-mass gas giant was found orbiting the star.

The planet is in a binary star system, the second star is HD 46375 B, a K9.5-M1.5, with a mass 0.580 of the Sun.
