A106fgF, a 2–5 m asteroid which either passed extremely close or impacted Earth on 2018-01-22. 2018 RC, near earth asteroid on 2018-09-03 (notable because it was discovered more than a day prior to closest approach on 2018-09-09). [43] A10bMLz, unknown space debris, so-called "empty trash bag object" on 2019-01-25. [44]
Near-Earth Object Surveillance Mission Near-Earth Object Camera NEOCam: Mission type: Asteroid impact avoidance, astronomy: Operator: NASA / JPL: Website: https://neos.arizona.edu/ Mission duration: 12 years (planned) [1] Spacecraft properties; Manufacturer: Jet Propulsion Laboratory [1] Launch mass: 1,300 kg (2,900 lb) [1] Start of mission ...
As of September 2023, there are over 32,955 near-Earth objects of which roughly 1,620 near-Earth asteroids are listed on the risk table. [1] Only around 19 objects on the risk table are large enough to qualify as potentially hazardous objects with a diameter greater than 140 meters (absolute magnitude brighter than 22). About 99% of the objects ...
The space rock last made a pass of Earth in 2013, and will make another approach in 2035, according to Nasa’s data. The object was first spotted by Nasa’s Near-Earth Object (NEO) Observations ...

Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...
In low-earth orbit, objects can collide at around 23,000 miles an hour, enough for even the tiniest debris to crack the windows on the International Space Station. Nearly 30,000 objects are ...
In 2013, NASA reactivated the WISE telescope to search for near-Earth objects (NEO), such as comets and asteroids, that could collide with Earth. [12] [13] The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). [13] As of August 2023, NEOWISE was 40% through the 20th coverage of the full sky ...
