What is HIP 42372

This yellow light left Ursa Major around the year 1759, when Halley's comet returned exactly as Edmond Halley had predicted and the Enlightenment was questioning every dogma. It is a G-type star, similar to the Sun in colour and temperature, one of those somewhat distant sisters of the daytime star. Ursa Major is probably the most recognised constellation of the northern hemisphere.
