{{Decadebox|207}}The 2070s (pronounced "twenty-seventies") is a decade of the Gregorian calendar that will begin on January 1, 2070 and will end on December 31, 2079. Notable predictions and known events 2070 - February – The Teen Age Message, an Active SETI message sent in 2001 from the 70-meter Eupatoria Planetary Radar, arrives at its destination, the star HD 197076.
2073 - May 3 - Asteroid {{mpl|2006 JY|26}} has a 1 in 71 chance of impacting the Earth.
[{{importance inline|reason=According to our article, it has an estimated "diameter" of 9 meters; even if it hits, the impact wouldn't be significant}}]
2074 - February 22 - Asteroid 2 Pallas will make a record close approach to Earth at 1.233 AU.
2075 - The ozone layer is expected to have fully recovered.[1]
2076 - 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.
2079 - May 1 - A total solar eclipse is predicted for New York City in the United States, as well as Nova Scotia in Canada.[2]
- 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.
