Accuracy of values of orbit major semiaxis and orbit eccentricity shown in asteroid orbit initial data is increased.

Page, containing the table of archive of asteroids approaches, added.

Page of asteroids closest approaches fixed. Now this page contains only the closest approaches at a distance less than 0.001 astronomical units.

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 Therefore, earlier the table of the closest approaches could contain out of date data.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 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.

Use of C3.js library instead of Java applets to interactively display graps of orbital evolution of selected asteroid or comet, 2D diagram of asteroids and comets, histogram of asteroids and comets, histogram of history update.
