HD 12055 is a candidate

light years from the Sun based on parallax, and is drifting further away with a radial velocity of +13 km/s.[1]

The visible component is an aging

luminosity of the Sun from its photosphere at an effective temperature of 5,196 K.[1]

This system is the most likely source of X-ray emission coming from these coordinates.[10]
