The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [10] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
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.

These images represent radar observations of Apophis on March 8, 9 and 10, 2021, as it made its last close approach before its 2029 Earth encounter.
Will an asteroid hit Earth in 2029? NASA keeps a close eye on potentially hazardous objects that come close to Earth. One of those is an asteroid with the name Apophis.
The first space rock, asteroid 2011 UL21, passed by Earth on June 27 at a distance of 4.1 million miles (6.6 million kilometers), or 17 times the distance between Earth and the moon.
The site provides a number of services to the NEO community. The main service is an impact monitoring system (CLOMON2) of all near-Earth asteroids covering a period until the year 2100. [69] The NEODyS website includes a Risk Page where all NEOs with probabilities of hitting the Earth greater than 10 −11 from now until 2100 are shown in a ...
In this dramatic illustration, a meteor falls toward Earth from space. A pair of asteroids that rammed into Earth more than 35 million years ago seemingly had no climate impacts, scientists said ...
