|---|---|
| The four innermost planets in the Solar System | Mercury, Venus, Earth, and Mars) |
| often called "Gas Giants. | Jupiter, Saturn, Uranus, and Neptune |
| medium sized star; located near edge of our galaxy; many thousands of times closer to Earth than any other star; provides energy that creates convection currents in atmosphere and ocean | Sun |
| nearly round objects that revolve around a star; in our solar system | Planets |
| small object made of ice with some gas, dust, and rock; a "tail" can appear as the comet revolves around the sun and is heated | Comet |
| a large, irregularly shaped object in space that orbits our Sun. Mostly made of rock | asteroid |
| small body moving in the solar system | Meteoroids |
| if it entered the earth's atmosphere | meteor |
| a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground it is called a | meteorite |
| compact solid bodies with rocky surfaces | Inner Planets |
| comprised mostly of an outer layer of molecular hydrogen and helium and a much thicker layer of metallic hydrogen. However, each may have a small solid core as large as three to 20 Earth masses at their center | Outer Planets |
| the closest planet to the Sun, very cold on one side and very hot on the other, smallest planet, and no moons. | Mercury |
| the 2nd planet from Sun, covered with volcanoes, no moon, hottest planet, and rotates very slowly and backwards. | Venus |
| the 3rd planet from Sun. Has one moon, orbits the sun in 365 days and one rotation in 24 hours, and life exists on this planet | Earth |
| the 4th planet from Sun. Called Red planet because red color caused by iron in the crust that has rusted, has polar ice caps and 1/2 the size of Earth. | Mars |
| the 5th planet from Sun. Has the most moons, largest planet, gas giant and has a large red spot. | Jupiter |
| the 6th planet from Sun. Spectacular rings made mostly of ice and frosted rock and gas giant made mostly of hydrogen gas | Saturn |
| 7th planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System | Uranus |
| the 8th planet from Sun. Another gas giant and blue color due to Methane gas, has the highest winds in solar system, and rotates counterclockwise. | Neptune |
| Since 2006, no longer termed planet, but now called "Dwarf Planet" | Pluto |
| Huge group of single stars, star systems, star clusters, dust, & gas bound together by gravity | Galaxy |
| an object that revolves around a planet | Moon |
