Star

A body in outer space, made of hot gasses, that shine in the night sky. (our sun is one of these!)

Atmosphere

Vocab Assignment #1

In your notebook, write down the following definitions

A layer of gases surrounding a planet, star, or moon.

Asteroid

1. Asteroid = An irregulary shaped rock that orbits the Sun.

2. Asteroid belt = The area in space between Mars and Jupiter where most asteroids orbit together.

3. Atmosphere = A layer of gasses surrounding a planet, star, or moon.

4. Comet = A space object made of ice and dust that orbitsa star and develops a long, bright tail as it nears its star.

5. Core = The center of an object

6. Crater = A hole in the ground caused by the impact of an object from space.

7. Dwarf planet = A nearly round object that orbits a star, This is smaller than a planet, and is not a satellite of another object.

8. Earth = The third planet from the Sun; the planet we live on.

9. Gas giant = A large planet that is mainly made up of gasses.

10. Star = A body in outer space, made of hot gases, that shines in the night sky

An irregularly shaped rock that orbits the Sun.

Asteroid Belt

The area in space between Mars and Jupiter where most asteroids orbit together.

Comet

Uranus

Orbit

Gravity

This means to move around another object. Our Moon does this to the Earth.

The force that pulls all objects toward each other. Without it we would float away!

A large blue-green planet that is seventh from

the Sun, a gas giant.

Vocabulary #2

A space object made of ice and dust that orbits a star and develops

a long, bright tail as it nears its star. Haley's is a famous one!

Revolution

core

Jupiter

The largest planet in our solar system and

the fifth from the Sun, a gas giant.

A single journey around the Sun. It takes Earth 365 days to revolve around the sun.

The center of an object. (Think about an apple.)

Crater

rotation

Mars

A hole in the ground caused by the impact of an object from space. The moon looks like swiss cheese because it has so many.

A single turn of a planet around an axis

spinning. It takes Earth 24 hours!

A small reddish planet that is fourth from the Sun, a terrestrial planet.

Dwarf Planet

Saturn

1. Gravity = The force that pulls all objects toward each other.

2. Jupiter = The largest planet in our solar system and the fifth form the sun; a gas giant.

3. Mars = A small reddish planet that is fourth from the Sun; a terrestrial planet.

4. Mercury = The smallest planet in our solar system and the closest to the sun a terrestrial planet.

5. Moon = Earth's only natural satellite.

6. Neptune = A large blue planet that is eighth from the the sun; a gas giant

7. Orbit = This means to move around another object.

8. Revolution = One orbit around the sun

9. Rotation = A planet turning on its axis.

10. Saturn = A planet with large rings around it that is sixth from the sun; a gas giant.

11. Solar system = a group of objects in space that orbit a star. There are 8 planets in ours!

12. Terrestrial = This word means 'like earth". It describes planets that are rocky and earthlike in size.

13. Uranus = A large blue-green planet that is seventh from the Sun; a gas giant.

Mercury

A planet with large rings around it that is sixth from

the Sun; a gas giant.

The smallest planet in our solar system and the closest to the Sun, a terrestrial planet

a nearly round object that orbits a star,

This is smaller than a planet, and is not a satellite of another object. Think~Pluto!

Earth

Solar System

Moon

Earth's only natural satellite.

A group of objects in space that orbit a star.

There are 8 planets in our solar system!

The third planet from the Sun;

the planet we live on.

Gas Giant

terrestrial

Neptune

This word means "like Earth". It describes planets that are rocky and Earthlike.

A large blue planet that is eight from the Sun, a gas giant.

A large planet that is mainly made up of gases.
