    2014 AF5 (also written 2014 AF5) is an Apollo near-Earth asteroid roughly 5–10 meters in diameter that passed less than 1 lunar distance from Earth on 1 January 2014.[3]

    Description

    From mid November 2013 until 1 January 2014 15:00 UT the small dim asteroid had an elongation less than 45 degrees from the Sun with an undetectable apparent magnitude of around 30.[4] While less than 18 degrees from the Sun any dim asteroid can be lost in astronomical twilight. On 1 January 2014 10:00 UT the asteroid passed 0.00062 AU (93,000 km; 58,000 mi) from the Moon and at 16:13 UT passed 0.00064 AU (96,000 km; 59,000 mi) from Earth.[3] The asteroid was then discovered on 2 January 2014 by the Catalina Sky Survey at an apparent magnitude of 18.9 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope.[1] By 3 January 2014 the asteroid was becoming dimmer than apparent magnitude 20.[4]
