It is classified as a near-Earth object and potentially hazardous asteroid of the Apollo or Amor group.Amor-vs-Apollo The V-type asteroid has a rotation period of approximately 1.5 hours. It was first observed on 10 November 2017 by the 60-inch Pan-STARRS 1 telescope at Haleakala Observatory in Hawaii. Orbit and classification It orbits the Sun at a distance of 1.0–1.7 AU once every 1 years and 7 months (585 days; semi-major axis of 1.37 AU). Its orbit has an eccentricity of 0.27 and an inclination of 9° with respect to the ecliptic. 2017 VR 12 is a V-type asteroid with a bright surface. thumb|left|Orbit of 2017 VR 12 thumb |left|Animation of 2017 VR 12 orbit from 1 October 2016 to 1 October 2018magenta 2017 VR 12 Green Mercury Gold Venus RoyalBlue Earth OrangeRed Mars 2017 VR 12 passed 0.0097 AU (3.76 lunar distances) from Earth on 7 March 2018, the closest approach by this asteroid currently known. It brightened to 12th magnitude, making it one of the brightest near-Earth asteroids of the year. It was observed by radar from Goldstone, Green Bank and Arecibo Observatory. Images revealed that 2017 VR 12 is a slightly elongated and angular body with a size of approximately 160 by 100 meters. left Physical characteristics Images obtained at Green Bank and Arecibo observatories in 2018, revealed that 2017 VR 12 is a slightly elongated and angular body with a size of approximately 160 by 100 meters. On 5 March 2018, a rotational lightcurve was obtained from photometric observations by astronomers at the Northolt Branch Observatories. Lightcurve analysis gave a rotation period of 1.5 hours with a brightness amplitude between 0.4 and 0.5 magnitude (U=n.a). Gallery Notes Amor-vs-Apollo It is either an Amor or an Apollo asteroid, depending on the definition of those orbital classes: JPL SBDB defines Apollo asteroids as those with a perihelion of less than 1.017 AU (smaller than Earth's aphelion), while the MPC uses a threshold of 1.000 AU (Earth's semi-major axis). 2017 VR 12's perihelion is 1.0004 AU.
