Jupiter also looks like a ‘4’ or ‘2l’.• Jupiter is the first gas planet and the biggest planet in the solar system.• It revolves around the Sun every 12 years. Jupiter• “The Great Red Spot” is a raging storm with winds of up to 200 miles an hour.• It rotates really fast. For one day on Earth, it is 10 hours on Jupiter.
• Saturn is 886 million miles from the Sun. • This planet is known for its rings made up of asteroids revolving round Saturn.Did you know?: Saturn was called“the evil planet” by roman gods. • Different parts of the planetSaturn rotate at different speeds. • Saturn is so light that it can float on water. The symbol for Saturn looks like an ‘h’.
• Uranus also has 13 rings but Did you know?: Uranus is named two are very far away from after the Greek god, “Sky God”. the planet.• The reason Uranus is blue is because of the methane from the Sun. Uranus• Uranus is 1.8 million miles from the Sun.• It is 4x bigger and 15x heavier than Earth.• The scientific hypothesis on why Uranus spins sideways Did you know?: Uranus` symbol also is because a space object looks like a Unknown from collided with it.

Other Space Objects• There are more than just planets in the galaxies.• There are moons also that orbit other planets.• Some are brakeage of planet.
Did you know?: There are no ‘did you knows’ for this one. • A asteroid is a piece of a planet that floats in space. • They have no real shape. • It is the biggest space object of the 5. • They can be caught in orbit around something. AsteroidAsteroidBelt
• Comets are the second biggest of the 5. • The are coated in ice and orbit around the Sun.Comets • The white part is the Ion tail. • The other one is the dust tail which is broken parts of it. • A comet`s orbit can vary. Did you know?: A comet also has a roman symbol.
• A meteoroid is smaller than an asteroid and comet.• They are usually the broken Meteoroid off parts of one.
Did you know?: Most people call meteors ‘shooting stars’ and wish for something on them.Meteor • A meteor is a meteoroid that passes through the atmosphere, Earth`s atmosphere. • It may burn up in the process but it might not.
• Meteorites are meteors that went past the Earth`s atmosphere and landed on the Earth. Did you know?: Most people• Meteorites are most commonly mistake meteors as commonly big in size. meteorites.• Some famous spots of where meteorites hit Earth include the following. Meteorite• - Wolf Creek in Western Australia• - Diablo Canyon in Arizona, United States
• The Sun is the center of our solar system.• The layers and parts include the following in order.• - The Core is the source of all the Sun`s energy. Temperature is about 15 million degrees Kelvin.• - The Radiation Zone contains energy from the core. Mostly hot at the top of the zone.• - The Convection Zone carries the magma/lava to the surface by letting them pass through thermal columns.The Sun• - The Photosphere is the part of the sun you can see. The energy from the Sun (sunlight) can then separate in space. Temperature is about 6,000 Kelvin.• - The Chromosphere is the outer thin layer of the Sun. This part can also be seen in eclipses.• - The Corona is the atmosphere of the Sun. It makes the solar wind.
Did you know?: Moon means Luna which is also the name of a pony in My Little Pony.• Earth`s moon was to Earth`s Moon believed to be formed by the Earth.• A long time, a piece of a planet collided with the (not completed yet) Earth.• The Earth`s gravitational pull made the moon revolve around Earth.

Types of Galaxies • There are different types of galaxies. • There are three types of galaxies.• The most common one is elliptical.
• Spiral galaxies have big arms made up of bright stars and dust.Did you know?: Our Milky Way is • The arms come out of thea spiral galaxy. bulging dust nucleus. Spiral Galaxies
Did you know?: Elliptical galaxies can be many different colors.Elliptical Galaxies• An elliptical galaxy is usually shaped like a football or a ball.
• Irregular galaxies don’t really has a shape.• Galaxies like this have no real Irregular Galaxies category.• The stars are spread out unevenly in this galaxy.
Light YearsLight years measures the distance light travels in one year.
Did you know?: The Hubble SpaceTelescope is a reflecting telescope.Telescopes • The two types of telescopes are refracting and reflecting. • Refracting uses convex glasses. • Reflecting uses curved mirrors.
Telescope(cont`d) Radio• These types of telescopes study radio waves in space and can freely move around in space.• When on Earth, it looks like a big satellite dish for TV.
• Any object that revolves around another. • A good example is aSatellite weather news satellite that revolves around Earth collecting data abound the weather.
Some examples: Mariner 2 • Space probes can travel far distances. • They travel to planets, collect information and send it back to Earth. Pioneer 10 Space Probes Voyager 1 Viking 1
• Spectroscopes measureSpectroscope how hot and composition of stars; planets, and galaxies.
