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.

We women are strong but we are not interested in showing it. Instead, we waste our time on outfits and makeup. We shouldn't do this because the world is a dangerous place and we may make the wrong people look at us. We will be happy at first, but soon we will realize our mistake and grow more unfriendly. We should fight, fight till the end. There are a few things that we need to change and I think we should totally change them. We should show how brave we are. We should prove to the world that we can handle everything. We can fight. And if you don't want to, forget it because you're just a coward. Leav it to the people who want to make things better for you. I will  fight. I WILL NOT GIVE UP. I WILL DO WHATEVER I CAN. I may not be good at everything, but that doesn't mean that I can't fight.

Duh. Nine year olds can be on this site, but Dear Dish It has frequently covered stories on some very graphic content. This site has always tried to service different age groups, but it's just impossible to do so.  What they really need to do is have a regular site for people who have aged out. Maybe a "Kidzworld Alumni" section.
