**2014 AF5** (also written [2014 AF5](/source/Astronomical_naming_conventions#Minor_planets)) is an [Apollo](/source/List_of_Apollo_asteroids) [near-Earth asteroid](/source/Near-Earth_asteroid) roughly 5–10 meters in diameter that passed less than 1 [lunar distance](/source/Lunar_distance_(astronomy)) from Earth on 1 January 2014.[3]

## Description

From mid November 2013 until 1 January 2014 15:00 [UT](/source/Universal_Time) the small dim asteroid had an [elongation](/source/Elongation_(astronomy)) less than 45 degrees from the Sun with an undetectable [apparent magnitude](/source/Apparent_magnitude) of around 30.[4] While less than 18 degrees from the Sun any dim asteroid can be lost in [astronomical twilight](/source/Astronomical_twilight). On 1 January 2014 10:00 UT the asteroid passed 0.00062 [AU](/source/Astronomical_unit) (93,000 [km](/source/Kilometre); 58,000 [mi](/source/Mile)) 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](/source/Catalina_Sky_Survey) at an apparent magnitude of 18.9 using a 0.68-meter (27 in) [Schmidt–Cassegrain telescope](/source/Schmidt%E2%80%93Cassegrain_telescope).[1] By 3 January 2014 the asteroid was becoming dimmer than apparent magnitude 20.[4]
