Test your knowledge with these top questions!
Why are Uranus's rings difficult to see from Earth?
Dark particles and narrow bands make Uranus's rings much fainter than Saturn's bright rings.
How does Uranus rotate compared with most planets?
An axial tilt of about 98 degrees gives Uranus seasons that last roughly 21 Earth years.
What is Jupiter's Great Red Spot?
Jupiter's Great Red Spot is a long-lived anticyclonic storm in the planet's atmosphere.
How does Saturn's average density compare with water?
Saturn's average density is lower than water's, so the planet could float in a container large enough to hold it.

Most planet names come from Roman mythology; Uranus instead follows the Greek name Ouranos.
Which spacecraft first visited Neptune?
NASA's Voyager 2 made the first close flyby of Neptune in 1989 and revealed the planet's active weather.
Which substance makes up most of Saturn's rings?

What material makes up most of Jupiter's faint rings?
Impacts on Jupiter's small moons loft dust into orbit, creating rings far dimmer than Saturn's mostly icy rings.
What do plumes from Saturn's moon Enceladus eject?
A hidden liquid reservoir beneath Enceladus's crust feeds the south-polar jets and helps supply Saturn's E ring.
How did astronomers predict Neptune's location before telescopes found Neptune?
Unexplained tugs on Uranus led mathematicians to predict an unseen planet before telescopes confirmed Neptune.
