Imagine that this photograph is our first close-up picture of an extrasolar planet called Incognita in the Alpha Beta system. Incognita has a density of about 3.6 g/cm3. We think that this solar system formed 1.6 billion years ago. The scene is about 250 km across. Suppose that you had no other information about Incognita. What can you infer about Incognita’s present state and past geologic history from this photo?
