2017 TD6 is a micro-asteroid, classified as a near-Earth object of the Apollo group, approximately 10–20 meters in diameter. It was first observed by Pan-STARRS at Haleakala Observatory, Hawaii, on 11 October 2017.

On 19 October 2017, the asteroid transited Earth at a nominal distance of 191,000 km; 119,000 mi (0.001278 AU), which corresponds to 0.5 lunar distances (LD). On the following day it also passed near the Moon at 113,000 km (0.00075575 AU). Peaking near a magnitude of 18, the object was too faint to be seen—except for the largest telescopes.

As of 2018, 2017 TD6 has a poorly determined orbit with an uncertainty of 6 and a short observation arc of 8 days only. Due to its small size, the asteroid is likely to remain unobserved until its next, still relatively distant approach, predicted to occur in March 2044, at a distance of 2,030,000 km (0.01358 AU) or 5.3 LD from Earth.
