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.
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 ]
This asteroid spends half of its orbit closer to the Sun than Earth and the other half farther away, causing it to oscillate above and below Earth's orbit annually. Its orbit experiences slight drifts that Earth's gravity corrects, keeping it between 38 and 100 times the distance of the Moon. Thus, 2016 HO3 continually dances around the Earth. [4]

Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
