Mars has two moons, the larger of which is Phobos. However Phobos is in trouble, as it is closest to Mars, at mere distance of 6 thousand kilometres.
Gravitational pull from Mars is pulling Phobos towards it, and it’s eventual doom. Phobos, which is being sucked towards Mars at 2 meters per year, has developed fissures on it’s surface, showing the stress being experienced by the moon.
Phobos is expected to be destroyed anytime between 30 to 50 million years.
