Electrostatic Removal of Fine-Grained Regolith on Sub-km Asteroids
Abstract
We show that sub-km sized asteroids near 1 AU experience a net loss of fine-grained regolith driven by electrostatic forces, implying that Apophis likely shows a desert pavement-like scenery, as seen on other similar-sized asteroids.
