The huge area outside Earth’s atmosphere where the stars, planets, and moons are found.

A large, round object in space that orbits (goes around) a star.

How big the Sun is compared to other objects. The Sun is much larger than Earth.

The Sun and all the planets, moons, rocks, and dust that travel around it.

A natural object that orbits a planet. Earth has one moon.

How the Sun and stars give off light and heat through burning gases.

How much light a star gives off and how bright it looks from Earth.

A group of stars that make a pattern or picture in the sky.

A huge group of billions of stars, gas, and dust held together by gravity.

Something related to space, stars, planets, or the universe.

When one space object blocks light from another, like the Moon covering the Sun.

Anything that exists in space, like stars, planets, or moons.

A small icy object that orbits the Sun and glows as it gets close.

The distance light travels in one year. It measures very large distances in space.

A unit of distance equal to the space between Earth and the Sun.

stellar circular motion

The movement of stars in a curved or circular path across the sky.

Everything that exists—space, time, stars, planets, and galaxies.

An imaginary line a planet spins around.

The galaxy that contains our solar system.

The different shapes of the Moon we see from Earth as it orbits us.

The path an object takes as it moves around another object.

A slanted position. Earth is tilted as it spins, which causes seasons.

The star at the center of our solar system that gives Earth heat and light.

A force that pulls objects toward each other.

The huge area beyond Earth’s air where the stars, planets, and moons are found. It is mostly empty and has no air or gravity like we feel on Earth.

How something moves from one place to another, like energy or electricity.

An object that can pull certain metals toward it.

A length of time between repeating events.

A property of matter that causes electric forces—positive or negative.

Earth spinning on its axis once every 24 hours.

To apply a force or push on something.

To move something from one place to another, like energy or heat.

The amount of matter in an object.

Related to an orbit or path an object follows around something else.

The amount of space something takes up.

When a planet spins on its axis.

When one object travels all the way around another object.
