VENUS

• A day on Venus lasts longer than a year
• Venus is often called the Earth’s sister planet
• Venus rotates in the opposite direction to most other planets
• Venus is the second brightest object in the sky
• Venus is the hottest planets in our solar system

EARTH

• The Earth’s rotation is gradually slowing
• The only planet with living things.
• Not named after a Greek, or Raman god
• There is only one natural satellite of the planet Earth
• Of all the planets in our solar system, the Earth has the greatest density

MARS

• On Mars the Sun appears about half the size as it does on Earth
• Has the biggest storm in our solar system
• Only 18 missions to Mars have been successful and there been 40
• Mars is home to the tallest mountain in the solar system
• Mars and Earth have approximately the same landmas

JUPITER

• Jupiter orbits the Sun once every 11.8 Earth years
• It the biggest planet in our solar system
• Jupiter is a gaint gas planet
• The Great Red Spot is a huge storm on Jupiter
• Jupiter has the shortest day of all of the planets

STAURN

• Saturn can be seen with the naked eye:
• Saturn is the fattest planet
• Saturn orbit the sun once ever 29.4 Earth years
• Saturn is made mostly of hydrogen
• Saturn has the most extensive ring in our solar system

URANUS

• Uranus was officially discovered by Sir William Herschel in 1781
• Uranus turns on its axis once every 17 hours, 14 minutes
• Uranus makes one trip around the Sun every 84 Earth years
• Uranus has two sets of rings of very thin set of dark coloured rings
• Only one spacecraft has flown by Uranus

NEPTUNE

• The atmosphere of Neptune is made of hydrogen and helium, with some methane
• Neptune was not known to the ancients:
• Neptune is the smallest of the ice giants
• Neptune has a very active Cilmate

MODEL

• Define: A physical representation of an object

COMET

• Define:an icy body that's in our solar system

HELIOSPHERE

• A bubble in space that's blown into interstellar medium by the solar wind

GALILEAN MOON

• The 4 moon discovered by Galileo in January 1609-1610

ASTEROID

• Are the class of small solar system bodies in our solar system. They have also been called planetoids especially the large one

METERIODS

• A sand to Boulder side piece of debris in the solar system.

METEOR

• The visible path of a meteoroid that has enters the Earth's atmosphere. They usually burn up to 40 to 70 miles above the Earth.

METERIOD

• An object originating in outer space that survives impact with Earth

SOLAR SYSTEM

• Consists of the sun and astronomical object gravitationally bound in orbit around it.

KUIPER BELT

• Is a region of the solar system beyond the planets extending from the orbit of Neptune to approximately 50AU from the sun. It is similar to the asteroid belt but much larger 20 time as a wide and 20 to 200 time as massive.

OORT CLOUD

• A hypothesized cloud of comet which may lie roughly 50,000 AU from the sun.

ASTRONOMICAL UNIT

• A unit of length equal to about 149,597,870.7 kl or 92,955,807.3 mi or approximately the earth/sun distance apart.

NASA launched Juno in 2011 as part of its New Frontiers program. Its mission: to fly to Jupiter and figure out how the planet was formed, what it’s made of, and how its formation affected that of the Solar System. (Actually, any information about Jupiter would be nice. The whole planet is a great big mystery.)
