Aten asteroid - Wikipedia
The Aten asteroid with the smallest known perihelion is also the one with the highest known eccentricity: (137924) 2000 BD 19 has an orbit with an eccentricity of 0.895, which takes it from a perihelion of 0.092 AU, well within Mercury's orbit, to an aphelion of 1.66 AU, which is greater than the semi-major axis of Mars (1.53 AU).
List of Aten asteroids - Wikipedia
This is a list of Aten asteroids, a group of near-Earth objects.As of January 2017, there are 1125 known Atens, [1] most of which remain provisionally designated without a number, [2] as they have not been observed at two or more oppositions.The list is divided into named members, brightest, notable and other record holding Aten asteroids.

NEO Basics - NASA
NEAs are divided into groups (Atira, Aten, Apollo and Amor) according to their perihelion distance (q), aphelion distance (Q) and their semi-major axes (a). Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth.
Asteroid Aten - Space Reference
Aten is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified Aten as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision. Aten orbits the sun every ...

Aten group asteroid to pass Earth by a close margin, reveals NASA
2023年11月21日 · NASA has revealed that Asteroid 2023 VW5 belongs to the Aten group of asteroids, which are Earth-crossing Near-Earth Asteroids (NEAs) with semi-major axes smaller than Earth's. They are named after the asteroid 2062 Aten and the first of its kind was discovered by American astronomer Eleanor Helin at Palomar Observatory on January 7, 1976.
Aten asteroid - Wikiwand
Nearly all known Aten asteroids have an aphelion greater than 1 AU. Observation of objects inferior to the Earth's orbit is difficult, and this difficulty may contribute to sampling bias in the apparent preponderance of eccentric Atens. Aten asteroids account for only about 7.4% of the known near-Earth asteroid population. [4]
2023 DW - Wikipedia
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.
