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.
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. [5] 2029 June 26 Total lunar eclipse. With an umbral eclipse magnitude of 1.84362, it will be the largest total lunar eclipse of the 21st century. 2029 December 20
The only object that has ever been rated at 4 on the Torino Scale (since downgraded), the Aten asteroid (99942) Apophis, has an Earth MOID of 0.00026 AU (39,000 km; 24,000 mi). This is not the smallest Earth MOID in the catalogues; many bodies with a small Earth MOID are not classed as PHO's because the objects are less than roughly 140 meters ...
In contrast, the Lunar distance (LD or ), or Earth–Moon characteristic distance, is a unit of measure in astronomy. More technically, it is the semi-major axis of the geocentric lunar orbit . The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds ; this is roughly 30 times Earth's diameter or 9.5 times ...
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 ...

Bennu will pass 0.005 au (750,000 km; 460,000 mi) from Earth on 23 September 2060, [1] while for comparison the Moon's average orbital distance (lunar distance) is 384,402 km (238,856 mi) and will only change to 384,404 km in 50 years time. [citation needed] Bennu will be too dim to be seen with common binoculars. [122]
The average distance to the Moon (or lunar distance (LD)) is about 384,400 km (238,900 mi), which is around 30 times the diameter of the Earth. [3] Below are lists of close approaches less than one LD for a given year. (See also near-Earth asteroids and NEO Earth Close Approaches.)
