99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
In 1995, two years prior to Stargate SG-1 ' s premiere, Williams starred in the 1995 movie Jungleground with three other actors from the Stargate franchise: Torri Higginson (Elizabeth Weir), J. R. Bourne (Martouf), and Lexa Doig (Dr. Lam). [4] In 2007, he played the lead, Gene Wright, in Frances-Anne Solomon's feature film A Winter Tale.
On December 24, 2004, 370 m (1,210 ft) asteroid 99942 Apophis (at the time yet unnamed and therefore known only by its provisional designation 2004 MN 4) was assigned a 4 on the Torino scale, the highest rating given to date, as the information available at the time translated to a 1.6% chance of Earth impact in April 2029.

Apophis will make an extremely close pass to the Earth on 13 April 2029, although there is no chance for an impact during this or any subsequent flybys in the near future. Observations of Apophis will commence on 8 April 2029, and a few days later, on 21 April, OSIRIS-APEX is planned to rendezvous with the asteroid. [ 90 ]
It gained some public interest when it became clear, in January 2005, that the asteroid 99942 Apophis would miss the Earth in 2029 but may go through one or another keyhole leading to impacts in 2036 or 2037. Further research has since been done, however, which revealed the probability of Apophis passing through the keyhole was extremely low. [1]
Asteroid (35396) 1997 XF 11 will pass 930,000 km (0.0062 AU) from the Earth. 2029 NASA's New Horizons spacecraft will exit the Kuiper Belt. [4] 2029 April 13 Near-Earth asteroid (99942) Apophis will pass Earth at a relatively small distance of 31,200 km (19,400 mi) above Earth's surface, closer than some geosynchronous satellites.

Ramses, or Rapid Apophis Mission for Space Safety, is a proposed ESA mission to a near-Earth asteroid 99942 Apophis.If approved, it is expected to be launched in April 2028, to arrive at Apophis in February 2029, before its closest approach to Earth.
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
