Near-Earth asteroid 1991 VG (marked with green lines) on 30 May 2017. This is a composite of several images obtained with the ESO VLT. The images have been combined in 7 stacks tracking the position of the asteroid, resulting in the object appearing as 7 dots as it moves in front of the background stars. The stars appear trailed due to the motion of the asteroid during each series. Additional images with the asteroid lost in the glare of the bright star have not been included. The instrument was FORS2 on VLT UT1, and the observations were obtained through a clear filter. Credit Hainaut/Micheli/Koschny
