Bright Halo Crater (Impact)
Living reference work entry
Halo around fresh impact craters displaying brighter optical albedo, higher radar backscatter, and distinctive thermal properties relative to their surroundings.
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).
