URANUS
WHAT DOES IT LOOK LIKE?
 The planet Uranus has a blue surface and is made mostly of water.
 It has four major rings that are surrounding the entire planet.
 The rings are very faint, the outer rings are very brightly colored and the inner
rings are very dark and narrow.
HAS EARTH EXPLORED THE PLANET?
WHAT SATTELITES HAVE EXPLORED IT?
 Uranus is a type of a planet that we know very little about Thirty years ago, we
thought Uranus was just smaller versions of Jupiter and Saturn.
 We now know, however, that the two outermost planets in our solar
neighborhood are not gas giants filled with hydrogen and helium gas, but rather
"ice giants" containing a large mixture of water, methane, ammonia and carbon
dioxide.
 A colour photograph of Uranus was taken by Voyager 2 in 1986 as it headed
towards the planet Neptune.
 The moon of Uranus Miranda imaged by Voyager 2.
FEATURES
 Uranus is the 3rd of the Gas Giant planets.
 Unlike the other planets of the solar system, Uranus is tilted so far that it
essentially orbits the sun on its side, with the axis of its spin nearly pointing at the
star. This unusual orientation might be due to a collision with a planet-size body,
or several small bodies, soon after it was formed.
 Uranus has a ring system, a magnetosphere, and numerous moons.
 Uranus is the coldest planet in the Solar System.
 Uranus is the second-least dense planet.
 Uranus has 27 moons.
TEMPERATURE
 The average temperature of Uranus is -357°F
 The temperature of the core, the hottest place is 8 540°F
ATMOSPHERE AND GASES PRESENT
 The atmosphere of Uranus is composed primarily of hydrogen and helium.
 At depth it is significantly enriched in volatiles such as water, ammonia and
methane.
THE NUMBERS OF MOONS ON URANUS
 Uranus has 27 moons that we are currently aware of.
 The main moons are Ariel, Umbriel,Oberon,Miranda and Titania
 Theyre roughly 50% ice and 50% rock.
DISTANCE FROM SUN
 2.887 billion km away from the sun.
ORBIT
 It takes 30,687 earth days for Uranus to orbit the sun.
 It takes 84 years for Uranus to orbit the sun.
 24,607 km per hour in its orbit around the sun.
DIAMETER, MASS, DENSITY
 The diameter of Uranus is 50,724 km.
 The density of Uranus is 1.27 g/cm³.
 The mass of Uranus is 8.68 x 10 to the power of 25= 14.54 M⊕
 The gravity of Uranus is 8.69 m/s².
OTHER FACTS
 Uranus was officially discovered by Sir William Herschel in 1781.
 Uranus turns on its axis once every 17 hours, 14 minutes.
 Uranus hits the coldest temperatures of any planet.
 Uranus is often referred to as an ice giant planet.
