2 Boötis is a single [6] star in the northern constellation of Boötes, [5] located 337 light years away from the Sun. [1] It is visible to the naked eye as a faint, yellow-hued star with an apparent visual magnitude of 5.63. [2] This object is moving further from the Earth with a heliocentric radial velocity of +4 km/s. [1]
Psi Boötis (ψ Boötis) is a single, [9] orange-hued star in the northern constellation of Boötes. It is a dim star that is visible to the naked eye with an apparent visual magnitude of +4.55. [2] Based upon an annual parallax shift of 13.26 mas as seen from the Earth, it is located about 246 light years from the Sun.
