499993

499993 is a numbered minor planet (asteroid) of the main asteroid belt. It was discovered on 3 September 2019 by the Pan-STARRS 1 survey at the Haleakala Observatory in Hawaii. The discoverer’s provisional designation was 2019 NA2. The asteroid was later assigned the permanent designation 499993 once its orbit was well determined.

The orbital elements of 499993 (as of 1 January 2023) are typical of main-belt bodies. Its semi‑major axis is approximately 2.45 astronomical units, placing it in the central region of the belt. The orbit has an eccentricity of about 0.18, giving it a perihelion distance of roughly 2.02 AU and an aphelion distance of around 2.88 AU. The inclination relative to the ecliptic plane is about 5.7 degrees. A period of about 3.85 Earth years completes one full orbit around the Sun.

The asteroid’s absolute magnitude is 15.9, which suggests a diameter of roughly 3–5 kilometers, assuming an albedo typical for S‑type asteroids. 499993 has not yet been assigned a name and is listed in official asteroid databases by its numeric designation.
