Even with an observation arc of 9 days, it was known that the minimum possible close approach distance to Earth on 18 February 2014 was 0.018 AU (2,700,000 km; 1,700,000 mi) with a small chance that the asteroid would pass as far as 0.13 AU (19,000,000 km; 12,000,000 mi) from Earth. Due to the uncertainty region of the asteroid, the asteroid could have been 75 degrees from the nominal position in the sky on 18 February 2014. 1132: 1288: 1252: 1752: 1913: 1902: 930: 745: 922: 737: 482:, and as such is often near the glare of the Sun as the asteroid seldom travels outside Earth's orbit when the Earth is nearby. The orbit was poorly constrained in 2014 since the asteroid had an observation arc of only 9 days creating an 431:
