Beta Aquarii is a single yellow supergiant star in the constellation of Aquarius. It has the official name Sadalsuud and the Bayer designation β Aquarii, abbreviated Beta Aqr or β Aqr. Based upon parallax measurements obtained during the Hipparcos mission, this component is located at a distance of approximately 540 light years (165 parsecs) from the Sun. It is drifting further away with a radial velocity of 6.5 km/s. The star serves as an IAU radial velocity standard.
Xi Aquarii is a binary star system in the equatorial constellation of Aquarius. It is visible to the naked eye with an apparent visual magnitude of 4.7. Based upon parallax measurements made during the Hipparcos mission, this system lies at a distance of around 179 light-years from the Sun.
46 Capricorni is a solitary star located around 790 light years away from the Sun in the southern constellation of Capricornus, near the northern border with Aquarius. It is visible to the naked eye as a dim, yellow-hued point of light with an apparent visual magnitude of +5.10. 46 Cap is also known by its Bayer designation of c Capricorni, and occasionally as c1 Capricorni to distinguish it from the nearby star c2 Capricorni. It is moving closer to the Earth with a heliocentric radial velocity of −15.5 km/s.
