100

Earth spinning on its axis once every 24 hours is called this, which causes our day and night cycle.

What is rotation?

100

A massive system containing billions of stars, gas, and dust all held together in space.

What is a galaxy?

100

The inner planets are primarily made of this solid material, which is why they are called terrestrial planets.

What is rock?

100

The outer planets are mostly made of these substances, which gives them their famous nickname.

What are gases? (Accept: Gas Giants).

100

This massive, glowing ball of gas sits at the center of our solar system and is actually a medium-sized star.

What is the Sun?

200

Earth traveling all the way around the Sun once every 365 days is called this.

What is a revolution?

200

The name of the specific cosmic home galaxy that our solar system belongs to.

What is the Milky Way?

200

This is the hottest planet in the solar system because its thick atmosphere traps heat like a greenhouse.

What is Venus?

200

This is the absolute largest planet in our entire solar system, famous for its giant storm called the Great Red Spot.

What is Jupiter?

200

Large rocky objects, mostly found in a "belt" between Mars and Jupiter, that are too small to be considered planets.

What are asteroids?

300

If the Moon is a New Moon tonight, this is the phase it will be in exactly two weeks (half a cycle) from now.

What is a Full Moon?

300

This is the invisible pulling force that keeps all the stars, planets, gas, and dust inside a galaxy from drifting away.

What is gravity?

300

Name all four inner planets in order, starting closest to the Sun.

What are Mercury, Venus, Earth, and Mars?

300

Every single outer planet shares this distinct physical feature made of ice, dust, and rock orbiting around them

What are rings?

300

A cosmic ball of ice, dust, and rock that develops a glowing tail of gas as it gets close to the heat of the Sun.

What is a comet?

400

This is the lunar phase where the Moon is positioned between the Earth and the Sun.

What is a New Moon?

400

True or False: The Milky Way galaxy contains only our one Sun and its eight planets.

What is False? (It contains billions of other stars and solar systems).

400

Unlike the gas giants, the inner planets have very few of these natural satellites orbiting them.

What are moons?

400

This icy blue outer planet is unique because it rotates completely on its side like a bowling ball.

What is Uranus?

400

This is the primary orbital difference between a planet and a moon.

What is a planet orbits the Sun, while a moon orbits a planet?

500

If the Moon is a Waxing Crescent tonight, this is the phase it will be in exactly two weeks (half a cycle) from now.

What is a Waning Gibbous?

500

Based on its shape, the Milky Way is classified as this specific type of galaxy.

What is a spiral galaxy? (Accept: Barred spiral).

500

This inner planet is nicknamed the "Red Planet" because its surface is covered in iron oxide (rust).

What is Mars?

500

Because they are so far away from the Sun, the outer planets take a much longer time to complete this orbital motion compared to inner planets.

What is a revolution? (Accept: A year).

500

The Sun appears much bigger and brighter to us than other stars in the galaxy for this specific reason.

What is because it is the closest star to Earth?
