	Gliese 752 Location of Gliese 752 in the constellation Aquila;

Gliese 752 is a binary star system in the Aquila constellation. This system is relatively nearby, at a distance of 19.3 light-years (5.9 parsecs).

The Gliese 752 system consists of two M-type stars. The primary star is the magnitude 9 Gliese (GJ) 752 A. The secondary star is the dim magnitude 17 Gliese (GJ) 752 B, more commonly referred to as VB 10. This stellar pair form a binary star system separated by about 74 arc seconds (~434 AU).^[8] This system is also known for its high proper motion of about 1 arc second a year. Component A has one known exoplanet.

The name and number are from the Catalogue of Nearby Stars, published by German astronomer Wilhelm Gliese in 1969.^[12]
