Shaking and Tumbling: Short- and Long-Timescale Mechanisms for Resurfacing of Near-Earth Asteroid Surfaces from Planetary Tides and Predictions for the 2029 Earth Encounter by (99942) Apophis

Autor: Ballouz, R. -L., Agrusa, H., Barnouin, O. S., Walsh, K. J., Zhang, Y., Binzel, R. P., Bray, V. J., DellaGiustina, D. N., Jawin, E. R., DeMartini, J. V., Marusiak, A., Michel, P., Murdoch, N., Richardson, D. C., Rivera-Valentín, E. G., Rivkin, A. S., Tang, Y.

Spectral characterization of near-Earth asteroids (NEAs) has revealed a continuum of space-weathered states for the surfaces of S-complex NEAs, with Q-class NEAs, an S-complex subclass, most closely matching the un-weathered surfaces of ordinary chon

Tidal resurfacing model for (99942) Apophis during the 2029 close approach with Earth

Autor: Kim, Y., DeMartini, J. V., Richardson, D. C., Hirabayashi, M.

We numerically investigate tidally induced surface refreshing on Apophis during its close approach with Earth within a perigee distance of 5.96 Earth radii on April 13, 2029. We implement a tidal resurfacing model with two stages: dynamics modeling o
