Bright Halo Crater (Impact)

Living reference work entry
DOI: https://doi.org/10.1007/978-1-4614-9213-9_24-1

Definition

Halo around fresh impact craters displaying brighter optical albedo, higher radar backscatter, and distinctive thermal properties relative to their surroundings.

Synonyms

Description

Optical and radar-bright halo surrounding fresh craters; often occurring with bright crater rays (Pieters et al. 1985) (Fig. 1). In some cases, a dark collar also is seen adjacent to crater ( Dark Halo Crater; impact, optical). Most optically bright fresh craters also have a radar-bright ring (Fig. 2); however, the reverse is not true (Thomson et al. 2013).
