HD 93385

HD 93385 is a star in the southern constellation of Vela. At an apparent visual magnitude of 7.5,^[2] it is too faint to be seen with the unaided eye. Parallax measurements made using the Gaia spacecraft show an annual shift of 23.04 milli-arcseconds. This is equivalent to a physical separation of around 142^[1] light years from the Sun.

This is an ordinary main sequence star with a stellar classification of G2/G3 V.^[3] The physical properties of HD 93385 are similar to those of the Sun; it is slightly larger with 107%^[4] of the Sun's mass, 117% of the radius, and 142% of the luminosity. The abundance of elements, other than hydrogen and helium, is nearly the same as in the Sun.^[6] It is currently at an unusual low level of surface activity and thus is a candidate Maunder minimum analog.^[4]

A physical companion star with an apparent visual magnitude of 12.29 is located at an angular separation of 10.32 arcseconds (equivalent to projected separation of 448 AU) along a position angle of 288°. It is estimated to have 45% of the mass of the Sun.^[8]

The survey in 2015 have ruled out the existence of any additional stellar companions at projected distances from 12 to 352 astronomical units.^[9]

Planetary system[]

This star hosts two close-orbiting, super-Earth-like planets, suspected since 2011 and confirmed in 2021.^[10][11] The first has 8.3 times the mass of the Earth and an orbital period of 13.186 days. The second is 10.1 times the Earth's mass with a period of 46.025 days.^[12] The third planet candidate on innermost orbit was discovered in 2017^[13] and confirmed in 2021.^[11]
