V372 Carinae is a single [9] star in the southern constellation of Carina. Located around 1300 light-years distant. It shines with a luminosity approximately 1742 times that of the Sun and has a surface temperature of 14132 K. [7] It is a Beta Cephei variable. [4] A magnitude 5.7 star, it will be faintly visible on moonless nights to the naked eye of a person located far from city lights.

In 1977, Mikołaj Jerzykiewicz and Christiaan Sterken announced their discovery that the star, then called HD 64722, is a variable star. [10] It was given its variable star designation, V372 Carinae, in 1981. [11]
