367943 Duende (provisional designation 2012 DA 14) is a micro-asteroid and a near-Earth object of the Aten and Atira group, approximately 30 meters (98 ft) in diameter.It was discovered by astronomers of the Astronomical Observatory of Mallorca at its robotic La Sagra Observatory in 2012, and named for the duende, a goblin-like creature from Iberian mythology and folklore.

The asteroid remained too faint to be recovered with automated astronomical surveys until early September, [20] but a more targeted observation with the Very Large Telescope recovered it on 27 July 2017 at apparent magnitude 26.8, while the asteroid was 0.4 AU (60,000,000 km; 37,000,000 mi) from Earth, making it one of the dimmest asteroid ...
Comet ISON, formally known as C/2012 S1, was a sungrazing comet from the Oort cloud which was discovered on 21 September 2012 by Vitaly Nevsky (Віталь Неўскі, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок, Kondopoga, Russia).
An asteroid that’s somewhere between 30 and 100 feet long is hurtling through space in the direction of Earth at 30,000 miles per hour. Asteroid 2012 TC4 is going to fly by Earth on October 12 ...
As of December 2024, all of the asteroids with predicted impacts were under 10 m (33 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors. Asteroid designation
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids.)

A.R. Gibbs of the Mount Lemmon Observatory in Arizona discovered the comet based on images acquired by the sky survey's 1.5-m reflecting telescope on 23 March 2012. [4] However, Gibbs did not recognize its cometary appearance and was listed as an asteroid on the Minor Planet Center's Near-Earth Object Confirmation Page. [5]
