Discovery of Uranus

Discovered on March 13, 1781

Sir William Herschel first to record the

movement of the dim planet

Herschel recorded a faint object that he originally

thought to be a comet

Became first planet discovered beyond the 5 planets

that are visible with the naked eye.

Naming Uranus

Herschel was rewarded greatly for

his discovery by King George III of

England

Herschel originally wanted to name

the new planet George Star after

his beloved king

The astronomy community strived

to keep the tradition of naming

the planets after the Roman gods. Uranus was the Roman and Greek

god of the sky.

The Size of Uranus (its huge)

Uranus is the 3rd largest planet in the solar system

Diameter: 31,763 miles (51,118 kilometers)

Uranus is about 4x bigger than Earth

Uranus' mass is about 8.68 x 1025 kg.

Mass is about 14x that of Earths


5/17

Density of Uranus

The density of Uranus is 1.27 g/cm.

Despite being larger than Earth its

density is just ofEarths


6/17

Internal Composition

Uranus is a frozen, gaseous planet.

Uranus is composed primarily of rock and various ices,with only about 15% hydrogen and a little helium

It appears that Uranus does not have a rocky core likeJupiter and Saturn but rather that its material is moreor less uniformly distributed

The upper atmosphere is thought to have a high-level

petrochemical haze that obscures features lower in theatmosphere.

Composition of Uranus


8/17

Atmospheric Composition

The planet is shrouded in an icy cloud layer

This is made up of frozen methane, ethane, and

acetylene

Circles Uranus at 185 mph (300 kph)

Uranus' icy atmosphere consist of

83% hydrogen, 15% helium and

2% methane


9/17

Magnetic Field

Uranus is surrounded by a strong magnetic field

Most planets have magnetic fields lined up with their

north and south poles

Uranus's magnetic field is closer to the equator than its

poles.

Makes the magnetic field wobble back and forth as the

planet spins.


10/17

Rate of Rotation

Uranus rotates once every 17 hours 14 minutes 24

seconds, as determined from the rate of rotation of its

magnetic field.

Various portions of its atmosphere rotate around theplanet as much as an hour faster or slower than this,

depending upon their direction and speed of motion,

relative to the overall rotation of the planet


11/17

Revolution Around the Sun

Uranus revolves around the sun is every

30,685 Uranus days.

On Earth that is equivalent to 84 years

Evidence of Water on Uranus?

Astronomers suspect there is a great amount water onUranus.

Since theyve never actually sampled the surface of the

planet, they cannot know if there is any water or ifthere is not.

Exploration of Uranus

Everything we know about Uranus comes from looking

through a telescope.

Only one spacecraft, Voyager 2, has ever made a close

flyby of the planet.

The Voyager 2 launched in August 20, 1977 by NASA

Voyager 2 is still the only spacecraft to do a flyby of

Neptune and Uranus

Voyager 2 is still in progress today having visited Jupiter,

Saturn, Uranus and Neptune

Evidence of Life???

Uranus has strong gravity and extremely cold

temperatures (-270 degrees F to -380 degrees F).

There is extreme energy from lightning and ultraviolet

light.

Uranus is made of methane, ethane and other

sophisticated gases. These materials, combined with the

energy from lightning, ultraviolet light, and charged

particles would not allow life to grow and begin

Fun Facts about Uranus

It has 27 moons

Uranus has 20 moons that are named plus 1 recently discovered one which as yet

has not been given an official name.

Uranus is the coldest planet in the entire solar system

Uranus is 1st planet discovered in modern age

Uranus can be seen without a telescope or binoculars.
