2019 TF₇ is an asteroid from the inner regions of the asteroid belt, approximately 800 kilometers (500 miles) in diameter. It will have a close flyby of earth on 26 June 2021.^[3]

Orbit and classification

It is a member of the Flora family (402), a giant asteroid family and the largest family of stony asteroids in the main-belt.^[4]^[5] It orbits the Sun in the inner main-belt at a distance of 1.1–3.6 AU once every 3 years and 7 months (1,317 days; semi-major axis of 2.35 AU). Its orbit has an eccentricity of 0.53 and an inclination of 22° with respect to the ecliptic.^[2]
