2019 LF6

2019 LF₆ is a near-Earth object of the Atira group. After 2021 PH27, it has the second-smallest semi-major axis among the known asteroids (0.555 AU), beating the previously-held record of 2019 AQ3. It orbits the Sun in 151 days. Discovered at only 19th magnitude, it is very difficult to see, never getting far from the sun and twilight. It only occasionally brightens above 16th magnitude. Discovery was made using the Zwicky Transient Facility.

2019 LF₆ orbits the Sun at a distance of 0.3–0.8 AU once every 5 months (151 days; semi-major axis of 0.56 AU). Its orbit has an eccentricity of 0.43 and an unusually high inclination of 30° with respect to the ecliptic. The asteroids 594913 ꞌAylóꞌchaxnim and 2019 AQ3 are the only known asteroids with closer aphelions. The orbital evolution of 2019 AQ₃ is similar to that of 2019 LF₆.
