NEAR Magnetic Field Observations at 433 Eros: First Measurementsfrom the Surface of an Asteroid

The magnetometer investigation aboard the NEAR-Shoemaker spacecraft has obtained extensive magnetic field observations throughout the 433 Eros environment, from distances in excess of 100,000 km to those conducted after landing on 12 February 2001. We report the apparent absence of global scale magnetization at this asteroid (H < 0.005 A · m−1; natural remanent magnetization per kilogram < 1.9 ...

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...
