The Pharos is a prominent impact structure on the moon Proteus, characterized by a diameter ranging from 230 to 267 kilometers (approximately 143 to 166 miles).
Overview of Pharos Crater
Pharos is recognized as by far the largest known impact structure located on Proteus, one of Neptune's inner moons. Its substantial size is particularly noteworthy because it accounts for over half the diameter of the satellite itself. Proteus has a mean radius of approximately 210 ± 7 kilometers (130.5 ± 4.3 miles), emphasizing the immense scale of the Pharos crater relative to its host body.
Detailed Size Specifications
To provide a clear understanding of the dimensions of Pharos and its host moon, refer to the following table:
| Feature | Measurement (Kilometers) | Measurement (Miles) |
|---|---|---|
| Pharos Diameter | 230 – 267 km | 143 – 166 mi |
| Proteus Mean Radius | ~210 ± 7 km | ~130.5 ± 4.3 mi |
Significance of Pharos
The colossal scale of Pharos makes it a critical geological feature for studying the history of cosmic impacts on smaller celestial bodies. Its size, especially when compared to Proteus itself, underscores the powerful forces that have shaped the surfaces of moons and planets throughout the solar system's history. As the largest impact structure on Proteus, Pharos offers valuable insights into past bombardment events that occurred within the outer solar system.
