753 Tiflis is a minor planet orbiting the Sun. It was discovered 30 April 1913 by the Georgian–Russian astronomer Grigory N. Neujmin at Simeiz Observatory and was named after Georgia's capital city Tiflis (now called Tbilisi). The object is orbiting the Sun at a distance of 2.33 AU with a period of 3.55 years and an eccentricity (ovalness) of 0.22. The orbital plane is inclined by an angle of 10.1° to the plane of the ecliptic.[2] In 1991, Ruth F. Wolfe included it as a member of the proposed Tiflis asteroid family.[3]
