Spectral properties and rotational spectral heterogeneity of 433 Eros

Composite spectra of different rotational aspects of the S asteroid 433 Eros were assembled from previous studies, covering the wavelength range 0ø33-2.5 grn. These data allow us to measure significant attributes of Eros's spectrum• its mafic mineral absorptions, and the degree and nature of compositional heterogeneity of its surfaceo We also evaluated previous Sasteroid taxonomies using indepe...

The spin state of 433 Eros and its possible implications

In this paper, we show that Asteroid (433) Eros is currently residing in a spin–orbit resonance, with its spin axis undergoing a smallamplitude libration about the Cassini state 2 of the proper mode in the nonsingular orbital element sin I/2 exp(ıΩ), where I the orbital inclination and Ω the longitude of the node. The period of this libration is 53.4 kyr. By excluding these libration wiggles, w...

Understanding Regolith Distribution on 433 Eros Using Analyses of Pit Chains

Introduction: From 2000 to 2001 the Near-Earth Asteroid Rendezvous NEAR-Shoemaker spacecraft orbited the asteroid 433Eros. Tens of thousands of high resolution images were collected in that year by the NEAR Multi-Spectral Imager (MSI). These images revealed that Eros is criss-crossed by hundreds of lineations, including both extensional and contractional features. A global database of all Eros ...
