Size comparison: the first 10 asteroids profiled against the Moon. Pallas is number two.
High-resolution images of the north (at left) and south (at right) hemispheres of Pallas, made possible by the Adaptive-Optics (AO)-fed SPHERE imager on the Very Large Telescope (VLT) in 2020. Two large impact basins could have been created by Palladian asteroid–forming impacts. The bright spot in the southern hemisphere is reminiscent of the salt deposits on Ceres.
