16646

16646 is a symmetrical asteroid, orbiting the Sun. Its diameter is approximately 4 kilometers, making it a small object in the asteroid belt. The asteroid's orbital path is characterized by a low eccentricity, indicating a stable and mostly circular orbit.

Discovered in 1993, the asteroid was identified by the Spacewatch project at the Kitt Peak National Observatory in Arizona, United States. The initial designation of the asteroid was 1993 TM1. Following further observations, the object was given the permanent minor-planet designation 16646.

06646 has a synodic period of 3.3 years, resulting in its orbital cycle being completed within a short period. Its specific distance from the Sun at perihelion is approximately 1.7 astronomical units, while at aphelion it reaches a distance of about 3.4 astronomical units. The asteroid's orbital inclination measures approximately 2.7 degrees from the plane of Earth's orbit.

Further details regarding 16646's physical properties, including its surface and composition, have yet to be determined due to the object's small size and limited availability of observational data. Therefore, experts continue to rely on orbital studies and various mathematical methods to better understand the asteroid's behavior and trajectory in its orbit around the Sun. This contributes to larger understanding of the asteroid belt and supporting continued research in the field of planetary science.
