Notable predictions and known events[edit]




  • February 22 - Asteroid 2 Pallas will make a record close approach to Earth at 1.233 AU.



  • c. May 31 - the planetoid 90377 Sedna is expected to reach its perihelion, its closest point to the Sun. It is expected to reach a distance of 76 AU, or 76 times the average distance Earth is from the Sun. Sedna has a highly elliptical orbit, thus it is difficult to locate; at its aphelion, it reaches a distance of about 942 AU. This date is subject to adjustment as Sedna's orbit is still being refined.


  • May 1 - A total solar eclipse is predicted for New York City in the United States, as well as Nova Scotia in Canada.[3]
  • June 6 - The smalldatetime fields in SQL-Server databases will wrap around to January 1, 1900.
  • August 11 - Mercury occults Mars for the first time since 578. It is difficult to observe, but is the best observable occultation of a planet by another in the 21st century.
