HD 111232 is a

light years based on parallax.[1] It is drifting away from the Sun with a radial velocity of +104 km/s,[2] having come to within 14.1 light-years some 264,700 years ago.[9] The absolute magnitude of this star is 5.25,[2]
indicating it would have been visible to the naked eye at that time.

This is an ancient,

luminosity of the Sun from its photosphere at an effective temperature of 5,648 K.[5]

Planetary system

A

Gaia DR3.[14] Later in 2022, these parameters were revised along with the detection of a second substellar companion, likely a brown dwarf.[15]
