Uranus is the 7th planet from the Sun, discovered by William Herschel in 1781. It has a thick atmosphere composed of hydrogen and methane that gives it a blue-green color. Uranus is an 'ice giant' composed mostly of ice and some rocky material. Unlike other planets, Uranus spins on its side with its axis perpendicular to its orbit, likely due to an ancient collision that tipped it over. Its seasons last over 20 years as a result. Uranus has 27 moons named after characters from Shakespeare and Pope.

Uranus ppt
QUICK FACTS • 7th planet from the Sun • First planet discovered by telescope • Uranus spins on its side • Discovered by William Herschel in 1781 • 3rd largest planet in our solar system
A BLUE-GREEN WORLD • Uranus has a thick mix of hydrogen and methane as an atmosphere. The methane causes the planet’s blue-green color. • Some astronomers call Uranus an ‘ice giant’ because most of its mass is ice and some rocky material.
URANUS VS. OUR WORLD Distance from Sun 1.7 Billion Miles 93 Million Miles Diameter 32,000 Miles 7926 Miles Length of Year 84 Earth Years 365.25 Days Length of Day 17.24 hours 23 hours 56 minutes Gravity .89 that of Earth 2.66 times that of Mars Temperature Average -319 degrees F Average 57 degrees F Number of Moons 27 1
A PLANET OFF KILTER • Uranus moves around the Sun with its rotation axis is perpendicular to its orbit around the sun. • It is thought that a planet-sized body hit Uranus early in its history, “tipping” it over. Because of this, Uranus’ seasons last over 20 years
A PLANET OF MANY MOONS • The 27 moons of Uranus are named after characters from the works of William Shakespeare and Alexander Pope.
GOD OF THE SKY • Uranus was named after the Greek god of the sky Ouranos, the earliest of the lords of the heavens. It is the only planet to be named after a Greek god rather than a Roman one. Before the name was settled on, other names were proposed, including Hypercronius ("above Saturn"), Minerva (the Roman goddess of wisdom), and Herschel, after its discoverer.
