Sub-kilometer asteroid on an eccentric orbit October 2019 yes (456938) 2007 YV 56 #FFC2E0 CSS Mount Lemmon Obs. 31 December 2007 (456938) 2007 YV 56 NEOApolloPHA 23 March 2018 (JD 2458200.5) 0 8.10 yr (2,959 days) 2.5556 AU 0.5952 AU 1.5754 AU 0.6222 1.98 yr (722 days) 87.984° 0.4984 ms / day 6.2441° 102.42° 265.73° 0.0047 AU (1.83 LD) 0.0019 AU 0.0571 AU 0.19 km (est. at 0.20)0.36 km (est. at 0.057) 21.0 (456938) 2007 YV 56 is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 190 - 360 m ft 2 us in diameter. It was discovered on 31 December 2007, by astronomers of the Catalina Sky Survey conducted at the Catalina Station in Arizona, United States. Orbit and classification 2007 YV 56 is an Apollo asteroid that crosses the orbit of Earth. Apollo's are the largest group of near-Earth objects with nearly 10 thousand known members. It orbits the Sun at a distance of 0.60–2.55 AU once every 2 years (722 days; semi-major axis of 1.58 AU). Its orbit has a high eccentricity of 0.62 and an inclination of 6° with respect to the ecliptic. This makes it also a Mars-crossing asteroid, as it crosses the orbit of the Red Planet at 1.66 AU, as well as a Venus-crosser due to its aphelion of less than 0.71 AU. The body's observation arc begins at Catalina with its official discovery observation in December 2007. Close approaches 2007 YV 56 has a minimum orbital intersection distance (MOID) with Earth of 0.0047 AU km mi on off 3 flip, which corresponds to 1.83 lunar distances (LD). It has an absolute magnitude of 21.0. This makes it a potentially hazardous asteroid, which are defined as having a MOID of less than 0.05 AU LD on and an absolute magnitude brighter than 22. Besides Earth, it also makes close approaches to Venus, Mars and the Moon. On 26 December 2007, five days prior to its discovery observation, it passed Earth at a nominal distance of 0.10037 AU LD on. On 2 January 2101, it is predicted to flyby Earth at 0.00159 AU LD on and pass the Moon at a similar distance five hours earlier as well (also see List of asteroid close approaches to Earth Predicted encounters). Physical characteristics The body's spectral type is unknown. Near-Earth asteroids are often of a stony composition. Diameter and albedo Based on a generic magnitude-to-diameter conversion, 2007 YV 56 measures 190 - 360 m ft us in diameter, for an absolute magnitude of 21.0, and an assumed albedo of 0.20 and 0.057, which represent typical values for stony and carbonaceous asteroids, respectively. Rotation period As of 2018, no rotational lightcurve of 2007 YV 56 has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown. Numbering and naming This minor planet was numbered by the Minor Planet Center on 22 February 2016 (M.P.C. 98584). As of 2018, it has not been named. References 30em 2016-02-06 last obs.
