Notes43 Persei is a bright yellow F-type dwarf approximately twice the mass and diameter of the Sun. This is a binary star with a low-mass companion detectable only though spectroscopic analysis, which orbits the primary over a period of 30.4 days.

43 Persei and its surroundings in northern Perseus. The brighter blue-white star to the east is Lambda Persei (actually much more distant than 43, but also far more luminous), while the orange-yellow patch to the northwest is the emission nebula NGC 1491. Imagery provided by Aladin sky atlas

43 Persei is a dwarf star not dissimilar to the Sun, though somewhat hotter (it belongs to the F-type rather than the Sun's cooler G-type yellow classification). It is 124 light years from the Solar System in the direction of the Milky Way's Perseus Arm. Its dwarf status combined with its distance make it a rather faint star in the sky, and very difficult to detect without the aid of a telescope. 43 Persei falls within the northern parts of the constellation Perseus, a little over two degrees from that constellation's border with neighbouring Camelopardalis.
