Space Vocabulary  

These words are all found in the AstroPuppies in Space DVD. Use the following definitions to help you understand and learn more about space exploration.

– A –

air
— Air is a mixture of gases that surrounds the Earth. All people and many animals breathe air.

asteroids — Asteroids are large rocky objects or very small planets. Most asteroids orbit the Sun in an area called the asteroid belt between Mars and Jupiter.

asteroid belt — The asteroid belt is a doughnut-shaped area of asteroids that orbit the Sun between Mars and Jupiter.

astronaut — An astronaut is a person that travels and works in space.

astronomers — Astronomers are people who study objects in outer space, such as stars, planets, galaxies, comets, and nebulae.

atmosphere — Atmosphere is the gas that surrounds a planet, moon or star. The layer of air that surrounds the Earth is called the atmosphere. There is no exact place where the atmosphere ends; it just gets thinner and thinner the closer it gets to outer space.

– B –

– C –

cloud — A cloud is a large group of tiny water drops or ice crystals that float in the air above the Earth.

– M –

mankind — Mankind means all the people in the world.

Mars — Mars, the fourth planet from the Sun, is called the Red Planet because its dirt is a rusty red color. There’s never any rain on Mars, so the planet is always dry and very dusty.

Mercury — Mercury is the closest planet to the Sun. It’s so close it’s really hot there during the day. But, it’s also terribly cold at night. Mercury has very little air and no water.

meteor — A meteor is a meteoroid that has entered the Earth's atmosphere, usually making a bright streak of light in the sky. It is sometimes called a shooting star. Most meteors burn up before hitting the Earth.

meteorite — A meteorite is a meteor that has fallen to Earth.

meteoroid — A meteoroid is a small piece of rock and dust that travels through space.

Milky Way — The Milky Way is a bright group of stars stretching across the night sky. Our solar system is in the Milky Way galaxy.

Pluto — Pluto used to be called a planet. But in 2006, astronomers decided that Pluto is too small to be called a planet. It’s now called a “dwarf” planet, which means it is a very small planet.
