Near-Earth Asteroid Tracking (NEAT) was a program run by NASA and the Jet Propulsion Laboratory, surveying the sky for near-Earth objects.NEAT was conducted from December 1995 until April 2007, at GEODSS on Hawaii (Haleakala-NEAT; 566), as well as at Palomar Observatory in California (Palomar-NEAT; 644).
2018 AH, largest asteroid to pass so close to Earth since 1971 on 2018-01-02. 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).

2024 YR 4 is an asteroid estimated to be 40 to 90 metres (130 to 300 ft) in diameter that is classified as an Apollo-type (Earth-crossing) near-Earth object.As of 17 February 2025, 2024 YR 4 was rated as a 3 on the Torino scale, with a 1-in-45 (2.3%) chance of impacting Earth on 22 December 2032.

Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
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. [7] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
An asteroid burned up in the Earth’s atmosphere just hours after it was detected last month, the European Space Agency revealed in its latest newsletter.. The asteroid, called 2024 UQ, was first ...
NASA is also working on an asteroid-hunting telescope known as the NEO Surveyor to find near-Earth objects capable of causing significant damage. Set to launch no earlier than June 2028, the ...
There are 1888 near-Earth asteroids listed in the risk table and 41,848 virtual impact dates, so for each asteroid in the risk table, there is an average of about 22 virtual impact dates. Only about 21 objects in the table are large enough, with a diameter greater than about 140 meters, to be considered potentially hazardous objects. The ...
