Near-Earth asteroid February 2018 yes #FFC2E0 (612901) 2004 XP 14 2004 XP14 radar.jpg 2004 XP 14 imaged by the Goldstone Solar System Radar in 2006 LINEAR 10 December 2004 NEOApolloPHA 1007 days (2.76 yr) 0 13 January 2016 (JD 2457400.5) 1.05156 AU Gm on 0.884900 AU Gm on 1.21822 AU Gm on on 0.158488 1.08 yr (393.87 d) 32.9505° 281.045° 273.695° 10.1555° 0.914014 ms /day 0.00316799 AU km on 130 - 260 m300–800 m 100 h d on on 19.4 (612901) 2004 XP 14 is a sub-kilometer asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group. It was first observed by the LINEAR project on 10 December 2004. Description thumb|left|2004 XP 14 as seen from France during its closest approach to Earth on 3 July 2006 Although initially there were concerns that it might possibly impact Earth later in the 21st century and thus merit special monitoring, further analysis of its orbit has since ruled out any such collision, at least in the foreseeable future. The size of 2004 XP 14 is not precisely known. Based on optical measurements, the object is between 300 and 800 meters in diameter. Radar observations place a lower bound of about 260 m us. 2004 XP 14's closest pass by Earth was above the west coast of North America at 04:25 UTC on 3 July 2006. The asteroid's distance from Earth's center of mass at that moment was 0.0028906 AU km mi on on, or just 1.1 times the Moon's average distance from Earth. It was observed immediately after this close approach by radar from three locations, from Goldstone in the Mojave Desert in the US, from Sicily, and from Yevpatoria RT-70 radio telescope, Ukraine, as well as optically from other observatories and amateurs. It was removed from the Sentry Risk Table on 17 March 2005. +H < 20 asteroids passing less than 2 LD from EarthAsteroidDateNominal approach distance (LD)Min. distance (LD)Max. distance (LD)Absolute magnitude (H)Size (meters)(152680) 1998 KJ 9 1914-12-31 0.606 0.604 0.608 19.4 279–900(458732) 2011 MD 5 1918-09-17 0.911 0.909 0.913 17.9 556–1795(163132) 2002 CU 11 1925-08-30 0.903 0.901 0.905 18.5 443–47769230 Hermes 1937-10-30 1.926 1.926 1.927 17.5 668–215869230 Hermes 1942-04-26 1.651 1.651 1.651 17.5 668–2158(27002) 1998 DV 9 1975-01-31 1.762 1.761 1.762 18.1 507–16372002 NY 40 2002-08-18 1.371 1.371 1.371 19.0 335–10822004 XP 14 2006-07-03 1.125 1.125 1.125 19.3 292–9422015 TB 145 2015-10-31 1.266 1.266 1.266 20.0 211–682(137108) 1999 AN 10 2027-08-07 1.014 1.010 1.019 17.9 556–1793(153814) 2001 WN 5 2028-06-26 0.647 0.647 0.647 18.2 921–94399942 Apophis 2029-04-13 0.0981 0.0963 0.1000 19.7 310–3402017 MB 1 2072-07-26 1.216 1.215 2.759 18.8 367–11862011 SM 68 2072-10-17 1.875 1.865 1.886 19.6 254–820(163132) 2002 CU 11 2080-08-31 1.655 1.654 1.656 18.5 443–477(416801) 1998 MZ 2116-11-26 1.068 1.068 1.069 19.2 305–986(153201) 2000 WO 107 2140-12-01 0.634 0.631 0.637 19.3 427–593(276033) 2002 AJ 129 2172-02-08 1.783 1.775 1.792 18.7 385–1242(290772) 2005 VC 2198-05-05 1.951 1.791 2.134 17.6 638–2061 References last observation: 2007-09-13; arc: 2.76 years JPL Close-Approach Data: (2004 XP14) http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2004XP14;cad=1#cad 30 March 2016 http://neo.jpl.nasa.gov/glossary/h.html https://web.archive.org/web/20010302182040/http://neo.jpl.nasa.gov/glossary/h.html dead 2001-03-02 Absolute Magnitude (H) NASA/JPL 2011-09-27 Asteroid fly-by eludes study Nature 10.1038/442855a 16929265 442 7105 855 2006Natur.442..855L 2006 Ledford Heidi free Date/Time Removed NASA/JPL Near-Earth Object Program Office http://neo.jpl.nasa.gov/risk/removed.html https://web.archive.org/web/20020602101400/http://neo.jpl.nasa.gov/risk/removed.html dead 2002-06-02 2012-03-19 Benner Lance A.
