Solar System

Definitions

•Solar system- Is a sun and everything within reach of it’s gravity.

•Sun- A star. Giant ball of hot gas. Produces heat, light, and other kinds of energy.

•Asteroid- Is a mini planet (the largest would stretch from Washington to Kentucky)

•Asteroid belt- A ring of asteroids, most asteroids are in a belt.

As you know

planets moons and the

sun rotate on an axis some like

Jupiter spin much

faster than

others.

Definitions

•Comets- Balls of ice, dust, and gas just a few miles across.

•Meteor- Is a asteroid plunged into the earth’s atmosphere.

• Solar flares- Sudden blasts of burning gas. Going millions of miles into space releasing a powerful burst of energy.

• Photosphere- Surface of sun glows bright white because of heat underneath it.

•Chromosphere-Is like the sun’s atmosphere.

The sun’s yellow right, not really. The colors of stars are red, white, and blue, hey

stars are patriotic, cooler stars are red, hotter stars, counting the sun, are white

and the hottest stars are blue.

Last of the Definitions

• Corona- (Or crown) is the sun’s upper atmosphere. Only visible during an eclipse.

• Sunspots- Dark blotches on the sun’s surface.

• Radiative Zone- Gamma rays bouncing of each other like pinballs making the radiation less dangerous.

25 miles under!

We are standing on Earth’s outer crust and only 25 miles below you is molten hot rock.

If you picture a basketball as the Earth the earth’s crust would be as thin as a hair. And mighty Mount Everest would be to small to see.

Is it at the Center?

The sun is at the center of the solar system.

Although scientists debated that for years. At first a second century Egyptian claimed the sun moon and planets evolved around the Earth. Not until the 16th century they proved him wrong.

Only 12!!!

Twelve humans have set foot on the moon. They were all Apollo astronauts.

They all walked between 1969 and 1972. No one has landed since.

Mars Venus and Mercury are most

likeEarth

Mars•After Earth most likely to support life

•Sunny Day 72F. (on the equator)

•At night goes down to -95F (the poles are even colder.

It’s icecaps are why Mars is most like Earth.

Last slide Continued

Venus•Venus is very hot.

•Lead, tin, and zinc would easily melt.

•Mercury the metal would boil.

•The rocky crust is mushy like a chocolate bar.

How like Earth: About the same size of Earth, spinning ball of rock.

Continued

Mercury• Closest to the sun (not the hottest)

•Screaming hot 800F

•Dark side a fright 300F

•Makes it one of the colder planets

•Little atmosphere letting heat escape.

Like Earth because a spinning ball of rock.

Jupiter• Cloudy atmosphere.

•Raging storms and lightning.

•Hydrogen (88%) Helium (11%) both invisible.

•Very colorful.

•Colors may be chemicals in the gases.

Uranus• Is tilted on it’s side.

• Sometimes the poles face the sun.

• Each pole get’s 42 years of sun and 42 years of darkness.

•

Neptune, Pluto

Neptune

• Like the great red spot Neptune’s dark spot is a storm that doesn’t die out.

• s around the storm are fastest in the solar system. (1200 mph)

Pluto

• Smallest planet.

• Twice as big as it’s moon (Charon)

Asteroids and Comets

Many asteroids cross the orbits of planets. If it crosses while the planet is there. Well you can guess what happens. The asteroid and the planet collide.

•With small asteroid nothing extraordinary happens.

•With big asteroid damage may be caused.

Halley’s CometIs only seen

every 76 years as it

travels past Earth

in orbit.

Comets only

form tails when

they are close to the sun.

When a comet goes through space it leaves a trail of dust and debris that stays in space

for a very long time.

Does The Name Fit?

In roman mythology Mercury is the messenger of the gods. Mercury is the speediest planet.Jupiter is bigger than all other gods and goddesses he is ruler of the heavens and the Earth.Pluto rules the underworld the most wicked place that you could ever imagine.Venus, is the goddess of love, beauty and laughter, she loves Mars.Neptune is the god of the sea which is often blue.

Symbols commonly used for planets along with the sun.

Society What??

The Earth is supposedly flat says the Flat Earth Research Society members. They gather proof that it is not round.
