20370

20370 is a near-Earth asteroid discovered on February 23, 1997, by the Near Earth Asteroid Tracking program. It is classified as an Apollo asteroid, meaning its orbit crosses that of Earth. Its orbital period is approximately 3.7 years, and its perihelion is less than 1 AU, while its aphelion is greater than 1 AU.

The asteroid has a diameter estimated to be between 1.2 and 2.8 kilometers. Its estimated absolute magnitude is 16.0, which translates to a relatively dim apparent magnitude when observed from Earth. Observations indicate that 20370 is a stony (S-type) asteroid, composed primarily of silicate minerals.

Due to its close approach potential to Earth, 20370 is listed on the Sentry Risk Table maintained by NASA's Center for Near Earth Object Studies (CNEOS). However, current orbital calculations show no significant risk of impact with Earth for the foreseeable future. The asteroid's orbit is well-determined, and subsequent observations have refined its trajectory, reducing uncertainties. Ongoing monitoring efforts continue to track its path.
