10416

10416 is a numbered minor planet located in the central region of the asteroid belt. It was discovered on 24 August 1999 by the LINEAR survey at the Lincoln Near‑Earth Asteroid Research facility in Socorro, New Mexico. The asteroid was observed over a multiple‑arc period, allowing its orbit to be well‑determined with an uncertainty parameter of 0.

The orbital parameters are typical of a C‑type asteroid in the main belt. Its semi‑major axis is 2.71 astronomical units, with an eccentricity of 0.12 and a perihelion distance of 2.38 AU and an aphelion of 3.04 AU. The orbital period is 4.44 years (1,623 days). The inclination of the orbit relative to the ecliptic is about 7.6°. These elements place 10416 in the outer part of the asteroid belt beyond the orbit of 3 asteroids like Hebe but within the range of the Massalia family.

Photometric observations indicate a rotation period of 9.8 hours and a brightness variation of 0.23 magnitudes, suggesting a moderately elongated shape. While its size is not precisely measured, albedo and absolute magnitude estimates place the diameter at roughly 6 to 7 kilometers.

The asteroid was named after the small town of Lake Placid, New York, in honor of the 1932 Winter Olympics held there. The official naming citation was published by the Minor Planet Center on 24 April 2003, following customary procedures for naming by the discoverer.
