Asteroid Interiors And Morphology

Abstract

The geophysical study of asteroids has moved from the realm of speculation and constraint to a more data rich environment where observations can be directly used to understand and probe the physical nature of these bodies. While many broad questions were posed in the Asteroids III chapter on asteroid interiors, in the current setting we are now able to probe more deeply into these questions, taking advantage of many different observations of asteroids across their entire size scale. The current chapter will take a very broad survey of what constraints currently exist in this area, what progress has been made in understanding these bodies analytically and through simulations, and what current theories can inform and guide future observations and tests of our understanding. The following topics are covered in this chapter: the strength of asteroid materials as inferred from meteors and meteorites, the density and porosity of asteroids as inferred from remote observations, global constraints on asteroid strength and morphology based on ground- and spacebased observations, analytical theories of asteroid strength and evolution, and the current state of numerical simulation techniques of asteroid interiors and morphology.
