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.
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.
The expedition is all part of the steps NASA and other space agencies have taken in recent years to protect humanity from threats posed by asteroids and other inbound space rocks, such as comets ...
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.
Dinosaur enthusiasts know that an asteroid hitting Earth’s Yucatan Peninsula 66 million years ago—actually, let’s define terms first: an asteroid is a piece of rocky space debris that ...
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 ...
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.
