Sub-kilometer asteroid February 2018 yes #FFC2E0 2014 DX 110 Pan-STARRS (F51) 28 February 2014 2014 DX 110 Apollo NEO 13 January 2016 (JD 2457400.5) 3.5778 AU Gm on on (Q) 0.82623 AU Gm on (q) 2.2020 AU Gm on (a) 0.62479 (e) 3.27 yr (1193.5 d) 5.7362° (i) 163.83° (Ω) 193.14° (M) 56.517° (ω) ~23 m us 20 - 40 m ft on 1.6e7 kg (assumed) 15–32 25.7 0.30162 ms / day (n) 0.12041 h min on on 6 0.00157599 AU km on 2014 DX 110 is a sub-kilometer asteroid, classified as a near-Earth object of the Apollo group, approximately 30 meters in diameter. It passed less than 1 lunar distance from Earth on 5 March 2014. With an absolute magnitude of 25.7, this asteroid is potentially the largest asteroid to come inside the orbit of the Moon since 2013 PJ 10 on 4 August 2013. The close approach was webcast live by Slooh and Virtual Telescope. Description thumb|left|Orbital diagram: close approach of 2014 DX 110 on 5 March 2014 2014 DX 110 came to opposition (furthest elongation in the sky from the Sun) on 15 February 2014, but the asteroid had a very faint apparent magnitude of about 23 and was only 10 degrees from the full moon. The asteroid was discovered on 28 February 2014 by Pan-STARRS at an apparent magnitude of 20 using a 1.8 m in on us Ritchey–Chrétien telescope. On 5 March 2014 at 21:00 UT the asteroid passed 0.00232 AU km mi on on from Earth and reached about apparent magnitude 15. At 22:22 UT it passed 0.00249 AU km mi on off from the Moon. By 6 March 2014 18:00 UT, the asteroid was less than 30 degrees from the Sun and dimming significantly. It has an observation arc of 5 days with an uncertainty parameter of 6. It was removed from the JPL Sentry Risk Table on 5 March 2014 using JPL solution 3 with an observation arc of 5 days. When the asteroid only had an observation arc of 4 days, virtual clones of the asteroid that fit the uncertainty region in the known trajectory showed a 1 in 10 million chance that the asteroid could impact Earth on 4 March 2046. With a 2046 Palermo Technical Scale of −7.11, the odds of impact by 2014 DX 110 in 2046 were about 13 million times less than the background hazard level of Earth impacts which is defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact. Using the nominal orbit, NEODyS shows that the asteroid will be 2.8 AU km mi on off from Earth on 4 March 2046.
