is a sub-kilometer asteroid with a somewhat elongated and angular shape, approximately in diameter. It is classified as a near-Earth object and potentially hazardous asteroid of the Apollo or Amor group. 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. is a V-type asteroid with a bright surface.
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 is a slightly elongated and angular body with a size of approximately 160 by 100 meters.
Physical characteristics
Images obtained at Green Bank and Arecibo observatories in 2018, revealed that 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 ().
