PLANETS

• Mercury
• Venus
• Earth
• Mars
• Jupiter
• Saturn
• Uranus
• Neptune

MURCURY

• •Mercury's eccentric orbit takes the small planet as close as 47 million km
• •Temperatures on Mercury's surface can reach 800 degrees Fahrenheit
• •no atmosphere to retain that heat,
• •temperatures on the surface can drop to -290 degrees Fahrenheit
• •Mercury speeds around the sun every 88 days

VENUS

• The temperature on Venus is 864 °F
• Venus is the most hottest planets in the solar system
• Venus is covered by a thick, rapidly spinning atmosphere
• Venus can be seen periodically passing across the face of the sun.
• Venus' atmosphere consists mainly of carbon dioxide,

EARTH

• •It is the only planet in the solar system that has life.
• •It is the only planet that has liquid water on its surface.
• •The Earth is larger than Mercury, Venus and Mars, the planets closest to it
• •The Earth’s diameter, the distance round its middle at the Equator, is 7928 miles, or 12760 kilometres.
• •The Earth is 93 million miles, or 150 million kilometres from the Sun.

MARS

• •Mars is not much farther from the Sun than Earth.
• •Mars has seasons like Earth too
• As a result, the temperature on Mars regularly drops to -125 degrees F (-82 degrees C) in the winter and only rises to 23 degrees F (-5 degrees C) in the summer
• •The dust storms on Mars are larger than on any other planet in the solar system
• •With mountains, craters and caverns like Earth and a rich history, we will be learning more about the Red Planet for centuries to come.

JUPITER

• •Jupiter has a diameter of 88,700 miles, or 142,750 kilometres.
• •Jupiter is the fifth planet in order from the Sun and is about 483 million miles, or 777 million kilometres from the Sun
• •Jupiter is the stormiest planet in the Solar System.
• • Jupiter is the first of the “gas giants”, Jupiter, Saturn, Uranus and Neptune.
• •The gas giants are entirely composed of dense layers of gas

SATURN

• •Saturn is the sixth planet in the Solar system and, when seen through a telescope, by far the most beautiful.
• •The rings were first seen by Galileo in 1610 through a telescope.
• •Saturn has at least 18 moons, satellites which orbit round the planet attracted to it by the planet’s gravity.
• •Saturn is 886 million miles, or 1426 million kilometres, from the Sun
• •Saturn takes 29½ years to make one complete orbit of the Sun. The Earth takes one year.

URANUS

• •Uranus cannot be seen from the Earth without a telescope.
• •Uranus was first seen by William Herschel in 1781 during a survey of the sky using a telescope. In 1782 George III appointed Herschel as Astronomer Royal.
• •Herschel also discovered 2 of Uranus’ moons with a larger telescope.
• •Uranus has a total of 27 moons, most of whom are named after characters in Shakespeare’s Midsummer Night’s Dream
• •Uranus orbits the Sun lying on its side and takes 84 years to complete one orbit.

NEPTUNE

• •The discovery of the planet Neptune was one of the most exciting discoveries in astronomy.
• •BUT, the existence of Neptune had actually been “discovered” a year earlier, in 1845.
• •Neptune is the 8th planet from the Sun
• •Neptune has a diameter of 29,297 miles, or 47,150 kilometres
• •Neptune is one of the four “gas giants
