Among the smallest worlds in our solar system, Mars' moon Deimos has long resisted easy explanation — its lumpy, potato-like form a quiet riddle orbiting in plain sight. A new study now proposes that a single subcatastrophic collision with a 320-meter asteroid reshaped the moon billions of years ago, leaving its irregular contours as a lasting testament to the violence woven into planetary history. In this reading, Deimos is not an oddity but a survivor — a small world bearing the permanent signature of one defining moment.
