Our best view yet of Pallas, the largest asteroid not yet visited by a spacecraft, reveals an extraordinarily violent history with numerous impacts, most likely due to its unusual orbit, a new study finds.

"Much remains unknown about this large asteroid. To shed light on Pallas' many mysteries, in a new study, scientists used the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) imager on the Very Large Telescope in the Atacama Desert of northern Chile to analyze the asteroid's shape and surface in unprecedented detail."

That is quite an image of Pallas. During April 2019, I tracked Pallas moving through Bootes using my 90-mm telescope (a bit more than 71x and 1-degree true FOV) including opposition on 06-April-2019, also later passing by Muphrid or Eta Bootis star, its retrograde motion ended 02-Jun-2019. Asteroid tracking with small telescopes can be much fun.
