| RI: Billy had a white rim, was oval shaped with a very smooth dark floor, darker than Oceanus Procellarum. All of Hansteed was very bright but it did have an irregular rough floor, maybe due to slumping. R2: Mons Hansteen was a very bright triangular-shaped feature above Billy. The two edges from the peak were relatively straight; the side facing Billy was irregular. |
