Oblique impact: Schiller


Is Schiller the best example of an oblique impact event anywhere in the solar system? Maybe. At 180km long it's an impressive sight. Gault and co-workers found in the 1970's that hollow projectiles could cause elongated complex 'divots' like this. Likely the 'object' was pretty irregular - based on recent views of asteroids and comet nucleii: and perhaps ~10km on one dimension. And impacted at an angle of <5 degrees. This C8 eyepiece log was rendered in ink-wash: slow, but rewarding!
