NASA's Mars Perseverance rover captured an image of Mars' moon Phobos passing in front of the Sun. Phobos, which has a radius of just 11 km, appears impressive against the distant Sun due to its proximity to the surface of Mars.
In it we see the larger of Mars' two moons, Phobos, passing in front of the Sun. NASA's Mars Perseverance rover acquired this image using its Left Mastcam-Z camera, one of two powerful cameras located high on the rover's mast.
The image, released by NASA, features colorful dots, which are actually artifacts rather than stars.
