Asteroid 2017VR12, 07 March 2018
Professional astronomers discovered the asteroid designated 2017VR12 on 10 November 2017, using the 150 cm Pan-STARRS 1 telescope in Hawaii. The body is estimated to be approximately 265 m in diameter and, because it has the potential to make close approaches to Earth and is big enough to cause significant regional damage if it were to strike, is classified as a potentially hazardous object.
On 07 March 2018, 2017VR12 passed Earth at 3.8 times the distance of the Moon, i.e. approximately 1.5m km. The object was closest to Earth at around 07:53 UT. I captured the following video of its motion, using a Celestron C8 telescope and SBIG8300 camera.
