|
Solar prominence |
Large loop of hot gas that come from the earth's surface |
|
|
|
Solar flare |
Violent eruptions of gas 110,000 000 |
|
|
|
Sunspot |
Cooler blotches on the surface 11 year cycle 3,500 |
|
|
|
Photoshere |
"Surface " Blotchy appearence caused by rising a falling hot and cooler gasses 5800 |
|
|
|
Chromosphere |
Thick layer of low density gas 3000 km thick 6000-20 000 |
|
|
|
Corona |
Outer atmosphere 3,000,000 |
|
|
|
Solar wind |
When the Corona bursts high energy particles ejected from the corona. It doesn't kill earth because the earth's magnetic field deflects it They exist because we see them in the sky Auroas Northern lights Southern lights |
|
|
|
Revolution |
Orbiting |
|
|
|
Rotation |
An object spinning on its axis |
|
|
|
Nebula |
Stars form Cloud of dust and gas (hydrogen) in space Stellar nurseries |
|
|
|
Prostar |
Early phase of star Gravity pulls the nearby material in and the pressure causes the spherical ball of gas to glow |
|
|
|
Main sequence star |
Central bond of stars (nuclear fusion) Energy from converting hydrogen to helium begins in the core and the star is a main sequence star "adulthood" |
More than 10 000 000 |
|
|
White dwarf |
Burn through hydrogen and never get very hot or bright Small dim Can't burn any other fuel so they collapse on themselves and pressure builds so they get white hot |
Low mass star |
|
|
Black dwarf |
When it's cooled down Dense dark body Carbon and oxygen |
|
|
|
Brown dwarfs |
The temp. And pressure make the brown dwarf glow but it never becomes a star |
|
|
|
Red giant |
After the star runs out of hydrogen it will burn through heavier elements in layers until they reach a max, of iron. After that, iron collapses and the outer layers are pushed out and become red |
|
|
|
Supernova |
The core and very high mass stars collapse suddenly when they run out of fuel resulting in a supernova explosion (outer layers blow away ) |
|
|
|
Neutron star |
1 million km wide Collapse into 10 km and the matter itself is compressed into neutrons 100 000 000 hot A spinning neutron star emits pulses of energy Pulsar |
|
|
|
Black hole |
A large amount of gravitational pull Nothing can escape After the supernova the core collapses smaller (maybe to a single point ) and becomes a black hole |
|
|
|
Inner planets |
Warm Small Solid cores rocky crusts Slow rotation Fast revolution |
|
|
|
Outer planets |
Large clips of ice gas and dust Fast rotation Longer revolution |
|
|
|
Asteroid |
Chucks of ice rock dust Orbits between Mars and Jupiter |
|
|
|
Meteoroids |
Chucks up rock floating through space A interact with planets |
|
|
|
Meteors |
Shooting stars Chuck of rock enters the atmosphere of a planet and glow hot |
|
|
|
Meteorites |
A meteor that has made it to the planets surface |
|
|
|
Comets |
Ice rock and gas Long orbit of the sun Grows a tail when it's near the sun Come from the kuiper belt or the oort cloud |
|
|
|
Trans - Neptunian objects |
Objects that circle the sun beyond the orbit (pluto) |
|
|
|
The kuiper belt |
Fast disk of millions and bodies orbiting the sun beyond Neptune Made of remains of the solar system |
|
|
|
Oort cloud |
Spherical cloud Small icy fragments Source of comets Barely affected by the sun's gravity 50 000-100 000 times the distance of the earth to the sun |
|
