2026 Cottrell, provisional designation 1955 FF, is a dark asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter. The asteroid was discovered on 30 March 1955, by IU 's Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. [ 12 ]
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
J002E3 is an object in space which is thought to be the S-IVB third stage of the Apollo 12 Saturn V rocket. It was discovered on September 3, 2002, by amateur astronomer Bill Yeung . Initially thought to be an asteroid , it has since been tentatively identified as the third stage of Apollo 12 Saturn V based on spectrographic evidence consistent ...
The images, obtained in March 2023 by the ESA's Solar Orbiter, represent what the agency says are the highest-resolution views of the sun's surface, known as the photosphere, to date.
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.

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. [10] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
