Planets & Their Order
This planet is the closest one to the Sun.
What is Mercury
This is the name for a natural satellite that orbits a planet.
What is a moon?
This object is at the center of our solar system.
What is the Sun?
This is the shape of a planet’s orbit around the Sun.
What is elliptical?
This is the nickname for Newton’s First Law.
What is the law of inertia?
These are the four rocky, inner planets.
What are Mercury, Venus, Earth, and Mars?
This is the current classification of Pluto.
What is a dwarf planet?
This force keeps planets moving in orbit around the Sun.
What is gravity?
This is the direction all planets orbit when viewed from above the North Pole.
What is counterclockwise?
This formula represents Newton’s Second Law.
What is F = ma (Force = mass × acceleration)?
This is the largest planet in our solar system
What is Jupiter?
This region lies between Mars and Jupiter.
What is the asteroid belt?
This source provides light and heat to the entire solar system.
What is the Sun?
These planets orbit the Sun faster.
What are the inner planets?
This is an example of Newton’s Third Law.

What is “asteroids are rocky and comets are icy with tails”?
This percentage of the solar system’s mass is held by the Sun.
What is over 99%?
This is the name of the flat disk in which most planets orbit.
What is the ecliptic plane?
This is what happens if no force acts on a moving object.

What is Ceres?
This is the classification of the Sun based on its size and colour.
What is a medium-sized yellow star?
This is why planets don’t fall into the Sun or fly away.
What is the balance between gravity and orbital speed?
These laws explain how planets stay in orbit.
