It was established also, that the period of rotation of Venus around axis - long, about 243 earth day is, more, than cycle time around of the Sun (224,7 day), therefore on Venus "day" is longer than year and the calendar is completely unusual. ... This vehicle has only once passed about Venus. ... They also have confirmed, that the period of rotation of the upper layer of clouds only 4 day, so a structure of a Venus atmosphere not similar on earth. ...

As announced by the IAU Central Bureau for Astronomical Telegrams in Circular No. 9004 on 11 December 2008, Bulletin C36 of the International Earth Rotation and Reference Systems Service announced that a positive leap second will be added on 1 January 2009. ... Bulletin C is mailed every six months, either to announce a time step in UTC or to confirm that there will be no time step at the next possible date.

Launched on February 17, 1996, the Near Earth Asteroid Rendezvous (NEAR) mission is to be the first of NASA's Discovery missions, a series of small-scale spacecraft designed to proceed from development to flight in under three years for a cost of less than $150 million. ... The ultimate goal of the mission is to rendezvous with and achieve orbit around the near Earth asteroid 433 Eros in February, 1999, and study the asteroid for approximately one year. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...
