Rings and Moons
20. __________ is defined as a large amount of debris encircling a planetary body.
21. __________is defined as a natural body orbiting around another celestial body.
22. __________has at least 16 moons. The four largest are Io, Europa, Ganymede, and Callisto.
23. __________has 2 small moons called Phobos and Deimos, which means fear and panic. These moons
were discovered in 1877.

25. __________has only one satellite, called Charon and is nearly a planet itself.
26. __________ has 8 known satellites, the largest of which is Triton.
27. __________ is not always the last planet-its orbit causes it to come closer to the sun than the 8th planet
for about 20 yrs.
28. __________ is often called the “vacuum” of the solar system because of its gravitational field.

has been raging for over 300 years.
30. __________is the brightest object in the sky besides the sun and the moon.
