Dataset: Near-Earth Asteroids (1900-2022)

About this Dataset

Near-Earth Asteroids (1900-2022)

Context

With over 90% of the near-Earth objects larger than one kilometer already discovered, the NEO Program is now focusing on finding 90% of the NEO population larger than 140 meters. Many of the charts and tables on these pages depend on diameters that can only be roughly inferred from an asteroid’s estimated absolute magnitude (H) and an assumed reflectivity, or albedo.

The absolute magnitude H is a measure of the asteroid’s intrinsic mean brightness, estimated from measurements of its apparent magnitudes at the various times it has been observed, at various distances from the Sun and Earth, and at various phase angles. Also, since the actual shape of the asteroid is usually unknown, it is simply assumed to be spherical.

Content

The data has Near-Earth Asteroids (NEAs) data such as detected date and discovery statistics.
