20621

20621 is a near-Earth asteroid discovered on January 28, 1997, by the Near-Earth Asteroid Tracking (NEAT) program. It is classified as an Apollo asteroid, meaning its orbit crosses Earth's orbit. Its orbital path is highly elliptical, bringing it relatively close to the Sun at its perihelion and extending far beyond the main asteroid belt at its aphelion.

The asteroid's size is estimated to be between 0.6 and 1.4 kilometers in diameter. Its composition is thought to be stony, similar to many other S-type asteroids. Although it is a near-Earth object, its current orbital parameters do not indicate a significant risk of impact with Earth in the foreseeable future. Scientists continue to monitor its trajectory to refine predictions and ensure its long-term path is well understood.

20621 orbits the Sun once every approximately 3.5 years. Its relatively close proximity to Earth during certain parts of its orbit makes it an object of interest for astronomical observation and potentially for future space missions. Studying such asteroids provides valuable insights into the early solar system and the potential for resource utilization in space. Further observations are ongoing to gather more detailed information about its physical characteristics and orbital dynamics.
