ANSWER: Mars
Explanation:
Mars’s largest moon Phobos is falling towards the planet and will soon disappear to form a ring much like Saturn and Jupiter. Phobos is set to be destroyed in 20 to 40 million years and the ring will exist from 1-100 million years. Phobos will not be able to resist tidal forces pulling it apart when it nears Mars, scientists have said. Mars’s other moon Deimos will remain. Scientists have also found the Sun’s UV rays caused Mars, which was once warmer and wetter, to lose its atmospheric CO2.
