The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1, 2024 BX 1, and 2024 RW 1 are the only nine asteroids discovered before impacting into Earth (see asteroid impact prediction). Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance ...
2023 DW is a near-Earth asteroid of the Aten group.It is approximately 50 meters (160 feet) in diameter, roughly the size of the asteroid that caused the Tunguska event, [a] and was discovered by Georges Attard and Alain Maury, from the MAP (Maury/Attard/Parrott) asteroid search program in San Pedro de Atacama on 26 February 2023, when it was 0.07 AU (10 million km) from Earth.

Contents. 2021 PH27. 2021 PH27 is a near-Earth asteroid of the Atira group. It was discovered by Scott Sheppard using the Dark Energy Survey 's DECam imager at NOIRLab 's Cerro Tololo Inter-American Observatory on 13 August 2021. 2021 PH27 has the smallest semi-major axis and shortest orbital period among all known asteroids as of 2021, [ 7 ...
A near-Earth object (NEO) is any small Solar System body orbiting the Sun whose closest approach to the Sun (perihelion) is less than 1.3 times the Earth–Sun distance (astronomical unit, AU). [ 2 ] This definition applies to the object's orbit around the Sun, rather than its current position, thus an object with such an orbit is considered an ...
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 km ...
469219 Kamoʻoalewa (/ kəˌmoʊʔoʊəˈlɛvə /), [ 6 ] provisionally designated 2016 HO3, is a very small asteroid, fast rotator and near-Earth object of the Apollo group, approximately 40–100 meters (130–330 feet) in diameter. At present it is a quasi-satellite of Earth, and currently the second-smallest, closest, and most stable known ...
162173 Ryugu (provisional designation 1999 JU 3) is a near-Earth object and a potentially hazardous asteroid of the Apollo group.It measures approximately 900 metres (3,000 ft) in diameter and is a dark object of the rare spectral type Cb, [11] with qualities of both a C-type asteroid and a B-type asteroid.
NEAR Shoemaker. Near Earth Asteroid Rendezvous – Shoemaker (NEAR Shoemaker), renamed after its 1996 launch in honor of planetary scientist Eugene Shoemaker, was a robotic space probe designed by the Johns Hopkins University Applied Physics Laboratory for NASA to study the near-Earth asteroid Eros from close orbit over a period of a year.
