Accuracy of values of orbit major semiaxis and orbit eccentricity shown in asteroid orbit initial data is increased.
01/28/2019
Page, containing the table of archive of asteroids approaches, added.
01/27/2019
Page of asteroids closest approaches fixed. Now this page contains only the closest approaches at a distance less than 0.001 astronomical units.
01/26/2019
Page of asteroids closest approaches fixed. Now the approach of each asteroid appears in the table only if it was defined during the last calculations of this asteroid. Earlier the table could show approaches defined during the previous calculations whereas during the last calculations the closest approaches could not be defined. Therefore, earlier the table of the closest approaches could contain out of date data.

Asteroids catalogue update on 10/09/2018. New objects added. Information about existing objects updated. See update history.
08/27/2018
Asteroids catalogue update on 07/01/2018. New objects added. Information about existing objects updated. See update history. In new calculations under investigation of asteroids orbit evolution approaches of asteroids with planets only at the distance less than 0.001 astronomical units were recorded. New differential equations of motion, based on the new principle of interaction, letting to get the integration results with higher accuracy were used.

Site Information

The space of the Solar system, besides the Sun, major planets and their satellites, is occupied by various bodies including both the smallest particles with a size equal to micron and multikilometer big asteroids and comets. Asteroids of Apollo, Amor and Aten groups are considered to be the most important in asteroids motion research because their orbits come into contact with the Earth's orbit or cross it and, in case of close approaches to the Earth, there is a danger of collision. Studying of short-period comets motion is also of great importance.

Nowadays hundreds of new asteroids of Apollo, Amor and Aten groups and some of short-period comets are annually discovered. Some of the discovered objects can closely approach the major planets of the Solar system, including the Earth. Information about already discovered objects is constantly updated.

Cataloguing of small bodies of the Solar system is the important stage in «asteroid risk» problem solution. Catalogues of asteroids and comets contain valuable information on distribution of small bodies in the Solar system and their orbits elements evolution.

The website contains the catalogue of orbital evolution of small bodies of the Solar system. It contains information about asteroids of Apollo, Amor, Aten groups1 and short-period comets2, about their orbital evolution and close approaches to major planets. This information can be helpful for motion studying of the potentially hazardous objects and allows to estimate the risk of their possible collision with our planet in future and timely take measures to prevent catastrophic consequences.

Current number of asteroids in the database is 20 956. Number of comets is 244.
