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.

Called a "mini-moon" of sorts by some, it temporarily entered Earth's orbit on Sept. 29 from the Arjuna asteroid belt, which follows a similar orbital path around the sun as the Earth.
An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or brighter. [2]
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.
