(7888) 1993 UC is a near-Earth minor planet in the Apollo group. [1] It was discovered by Robert H. McNaught at the Siding Spring Observatory in Coonabarabran, New South Wales, Australia, on 20 October 1993. [1] The asteroid has an observation arc of 23 years and has a well determined orbit. [1] Its estimated size is 2.3 to 5.2 km. [4]
On 20 March 2013, the asteroid passed 49 lunar distances or 0.12598 AU (18,846,000 km; 11,711,000 mi) from Earth at a relative velocity of 21.8 km/s (49,000 mph). [1] The approach posed no threat to Earth. (7888) 1993 UC is not classified as a potentially hazardous asteroid (PHA) because its Earth MOID ( Minimum Orbit Intersection Distance) is only 0.089 AU, [1] and only objects with an Earth MOID less than 0.05 AU are considered PHAs. [5]
It was discovered to be a binary asteroid by Arecibo Observatory in March 2013. [6]
On 29 April 2146, the asteroid will pass 0.0346 AU (5,180,000 km; 3,220,000 mi) from asteroid 4 Vesta. [1]
