Mars spins a little more quickly each year, according to data collected by NASA’s now-retired InSight lander.

    This got me curious as to when and how fast Phobos is spiraling inward and found this on NASA’s website.

    Phobos is gradually spiraling inward, drawing about six feet (1.8 meters) closer to the planet each century. Within 50 million years, it will either crash into Mars or break up and form a ring around the planet.
