Vishnu Reddy, Juan Andreas Sanchez, Michael Gaffey, Paul Abell,, Lucille Le Corre, Paul Hardersen
TL;DR
This study analyzes the surface composition of near-Earth asteroid Toutatis, revealing it is consistent with undifferentiated L-chondrite material, contrasting earlier findings suggesting a differentiated, pyroxene-rich body.
Contribution
It provides new compositional analysis of Toutatis, clarifying its undifferentiated nature contrary to previous hypotheses.
Findings
Toutatis has an undifferentiated L-chondrite surface composition.
Contradicts earlier observations suggesting a differentiated asteroid.
Supports the idea of primitive, undifferentiated asteroid surface.
Abstract
Surface composition of near-Earth asteroid (4179) Toutatis is consistent with an undifferentiated L-chondrite composition. This is inconsistent with early observations that suggested high pyroxene iron content and a differentiated body.
