Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
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.
An asteroid that orbited near Earth for a few months as a mini-moon may be a chunk of the moon that was blasted off by an impact thousands of years ago. An asteroid that orbited near Earth for a ...
2020 CD 3 (also CD3 for short) [11] [12] is a tiny near-Earth asteroid (or minimoon) that ordinarily orbits the Sun but makes close approaches to the Earth–Moon system, in which it can temporarily enter Earth orbit through temporary satellite capture (TSC).
Called 2024 MK, the space rock will make its closest approach to Earth Saturday morning, passing by at about three-quarters the distance from Earth to the moon. A 7,579-foot (2,310-meter) asteroid ...
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. Researchers ...
2017 AG 13 is a small Aten asteroid that made a close approach of 0.54 lunar distances from Earth on January 9, 2017. [4] It was the largest asteroid to pass less than 1 lunar distance from Earth since 2016 QA 2 on August 28, 2016. The Catalina Sky Survey observed it first on January 7, 2017, only two days before its closest approach.
In 2016, astronomers spotted an asteroid about the size of a ferris wheel in an Earth-like orbit around the Sun. Turns out it's actually a chunk of the moon.
