Space Term Glossary

Asteroid (also called planetoid) - A medium-sized rocky object that orbits the Sun. It's smaller than a planet but larger than a meteoroid. Also, any number of small bodies that revolve around the Sun.


Atmosphere - The air all around Earth.

Black Hole - An object with gravity strong enough to suck anything into it, even light.

Celestial Bodies - Natural objects visible in the sky - planets, stars, meteoroids, etc.

Comet - A giant snowball of ice and dust that revolves around the Sun. When it gets near the Sun, ice melts and looks like a tail. Haley's comet is probably the most famous comet.

Constellation - A group of stars that make a shape (they look like connect-the-dots) - usually named after mythological characters, people, animals and things.

Eclipse - This is when one celestial body cuts off the light of another - like when the moon covers the Sun for a brief moment.

Galaxy - A large group of stars. Our galaxy (called the Milky Way) includes the Sun.

Gravity - The natural force of attraction that pulls objects together - this is also what keeps our feet on the ground.

Great Red Spot - A huge colorful swirl of gases that spin counterclockwise on Jupiter.

Light Year - The distance light travels in a vacuum in one year (about 9.5 trillion km/6 trillion miles.)

Meteor (also a shooting star or a falling star) - A bright streak of light in the sky caused by a meteoroid or a small icy particle as it burns up entering Earth's atmosphere. Very large, bright ones are called fireballs and bolides.

Meteorite - A part of a meteoroid found on Earth.

Meteoroid - A small rock in space.

Orbit - The path that an object moves around a second object or point. For example, Earth orbits the Sun.

Planet - An object bigger than an asteroid orbiting a star. Our solar system has nine planets.

Satellite - A body that revolves around a larger body. The moon is a satellite of Earth. High-tech manmade satellites orbit Earth and the Sun, transmitting pictures, TV channels and phone signals.

Shooting Star - See meteor.

Solar System - The Sun, the nine planets and any other celestial bodies that orbit the Sun.

Solar Wind - A thin flow of energetic and gas charged particles that stream from the Sun. These blow throughout the solar system at speeds of hundreds of kilometers per second.

Speed of Light - 299,792,458 meters/second (186,000 miles/second.) Einstein's Theory of Relativity says that nothing can go faster than the speed of light. Of course, the crew on the Starship Enterprise knows better.

Star - Any celestial body that is visible at night (because it's brightly lit) from Earth at night.

Universe - All the matter and energy out there - this includes the Earth, galaxies, solar systems, you, your favorite pop star and everything else.

White Dwarf - The 'remains' of a star after it has collapsed. It is white looking (because it's so hot) and is extremely dense.

Angry because some turd threatened the Bomb outcast council saying that it's just the role player's council rip-off. I feel like I'm disrespected.

Music is subjective.  I don't think you can debate it.  If one likes repeated sentences played over catchy beats, that's okay.  If one likes deep lyrics with an underlying meaning, that's okay.  I listen to many different types of music, including classical anytime *and* that repeated sentence played over a catchy beat whenever I'm "partying".
