NASA’s Mars Odyssey orbiter has captured the best view of the planet’s moon Phobos yet. The image, which depicts Phobos in its full moon phase, gives us one of the best views of this strange moon that we’ve ever seen.
Phobos is the biggest moon orbiting Mars, but that isn’t saying much: At only about seven miles across, it’s really more of a large asteroid than a proper moon. In fact, many astronomers suspect Phobos was once an asteroid that Mars snatched up and then made its moon.
Because of its small stature, scientists have struggled to properly study Phobos. Short of landing on the moon or placing a spacecraft in orbit around it, the best we can do is take some distant pictures. And now, thanks to the new photo series, we can actually start to learn something about it.
