Planets for Astronomy
| Question | Answer |
|---|---|
| Asteroid/Asteroid Belt | Thin and not constant flying rocks. |
| Meteor | Burns up in the atmosphere |
| Meteoroid | An asteroid heading to the earth but as soon as it comes through the atmosphere it is called a meteor. |
| Meteorite | As soon as they hit the earth they go to the antarctic and are found with metal detectors |
| NEA's | Near Earth Asteroids. It is the impact when an Asteroid hits a planet |
| Valles Marineris | Grand canyon of Mars |
| Phobos | Fear |
| Deimos | Terror |
| Retrograde | Spinning the wrong way, aka clockwise. |
| Albedo | How well something reflects light. Water, snow, ice, atmosphere and clouds are great for bright albedo. |
| Galilean Moons/IO | Geologically active because of volcanoes |
| Europa | Giant iceball |
| Ganymede | The number one largest moon in the solar system |
| Vallhalla | Multi ring basin in callisto |
| IO plasma Torus | Ionized particals out of IO's volcanoes form this |
| Oblate | Out of round |
| Olympus Mons | Biggest Volcanoe in the solar system |
| Shooting star | Flaming Meteor |
| Miranda | Jagged Surface layers and chevrons |
| Titan | An atmosphere fifty percent thicker than the earths atmosphere |
| Jovian Planets | The outer planets |
| Tidal embrace | Made the assumption that the moon revolves around the earth |
| Evening star/Morning Star | Mercury |
| Terrestrial Planets | Planets made out of mostly rock |
| Great Dark Spot | Giant storm on Neptune |
| CLyde Tombar | American who discovered Pluto at the Lowell Observitory |
| Percival Lowell | Established the Lowell Observitory |
| Great Red Spot | Giant storm in Jupiter |
| Inner planets | Mercury Venus Earth Mars |
| Differential Rotation | When different parts of rotating objects move with different rates of rotation |
| Eccentricity | A very eliptical orbit |
| Crust | 30-40 miles thick |
| Outer core | 1400 mi thick made out of primarily iron and nickel |
| Inner Core | Solid because of lots of pressure, 800 miles |
| Magnetosphere | Deflects cosmic rays and solar wind |
| Trophosphere | Weather sphere where weather occurs |
| Statosphere | About 28 miles high |
| Ozone Layer | Absorbs UV light |
| Greenhouse Gasses | Gasses that prevent heat from getting out |
| Perturbing | To pull or hold back or mess up the orbit of another planet |
| Luminescence | General term applied to cool light made by a cool body |
| Chemoluminescence | A chemical reaction that produces cool light |
| Electro Luminescence | Static Light |
| Bioluminescence | Living things produce this |
| Flourescence | Absorbtion of high energy UV |
| Phosphor | Material that luminesces |
| Phosphorescence | Drops halfway and gives off physical light |
| Aurora Borealis | Northern lights caused by solar wind |
| Aurora Australius | Southern lights caused by solar wind |
| Solar wind | High energy electrons and protons coming from the sun. Enter the north and south after being deflected by the Magnetosphere. Hits oxygen and Nitrogen and causes reaction. |
| CME-Coronal Mass Ejections | Reinforces solar wind |
