Read the passage and answer the question below.

The planet with the most moons in the Solar System is Jupiter, with a total of 63 confirmed moons (as of 2009). Of course, it’s always possible that more moons will be discovered orbiting Jupiter in the future, and that number will go up.

Eight of Jupiter’s moons are regular satellites, with 4 large, spherical moons, and 4 smaller moons that orbit closer to Jupiter. Jupiter has an additional 55 tiny irregular satellites.

The planet with the second highest number of moons is Saturn, with 61 moons. With such a close total, more moons could easily be discovered circling the rings planet, and push its total higher.

The next planet with a high number of moons is Uranus, with 27 known moons.

This is followed by Neptune with 13 moons, Mars with 2 moons, and the Earth with its single moon.

Mercury and Venus have no moons. Although Pluto isn’t a planet anymore, it does have a total of 3 moons.

Earth has only one, but our moon has a big influence on the lives of humans on earth. In ancient times, people believed that moonlight could affect people’s brains. The Latin word for the moon was Luna. Words like “lunatic” and “looney” come from that idea. Many people still believe that more babies are born, and more people die when the moon is full. Scientific studies that have been done to see whether the numbers of births and deaths increase when there is a full moon show that there is no increase. The gravitational pull of the moon affects the tides in the ocean but does not seem to affect the births and deaths of people. Does the full moon cause people to fall in love? That’s another question!
