Planets
List the planets in order from closest to the sun to furthest.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Kant or Laplace
When looking up into the sky this disk shaped collection of stars and planets can be seen.
What is the Milky Way Galaxy
List all three laws of motion
Unless acted on by an unbalanced force an object in motion tends to stay in motion and an object in rest tends to stay in rest.
When an unbalanced force acts on an object the object accelerates. The net force is equal to the mass multiplied by the acceleration.
When one object exerts a force on another object the second object excerpts an equal force on the second object in the opposite direction.
When humans first began to study the stars what did they used to do so?
Their eyes.
Mercury, Venus, Earth and Mars are all categorized as what type of planet?
Terrestrial Planets
Solar System model where the sun is in the middle of the Solar System.
Heliocentric Model of the Solar System
When measuring the distance between galaxies this unit of measurement is used.
Light Year

What is people use to discover that Earth was inside the Milky Way?
Telescopes
Gas Giants
Solar System Model where the Earth is in the middle of the Solar System.
The Geocentric Model of the Solar System.
List these items from smallest to largest; Milky Way, Earth, Solar System
Earth, Solar System, Milky Way
Give an example of Newtons Second Law of Motion.
Teachers Choice.
How did we figure out that we are not the center of our Galaxy?
Distance between us and stars.
Instead of a planet, this collection of space rocks orbits the sun between Mars and Jupiter.
The Asteroid Belt
What way can we gather evidence to support the formation of the Solar System
By watching other Star Systems form and move.
How is mass and gravitational pull related?
The bigger the planet the greater the gravitational pull, the smaller the planet the lower the gravitational pull.
Give an example of Newtons Third Law of Motion.
Teachers Choice.
Who created the telescope used to find other galaxies apart from our own?
Edwin Powell Hubble
What causes the outer planets to be made of gas and ice while the inner planets are made of metal and rock?
The distance the planets are from the sun.
What are the Steps of the Formation of the Solar System!
1 - a rotating cloud of dust and gas
2- spins faster and forms the sun
3 - flattens into a disk
4 - materials collide and clump together
5 - forms planets and the solar system
How is orbital velocity and the disturbance a planet is from the sun correlated?
The further away a planet is the slower it will orbit. The closer a planet is the faster it will orbit.
What is the Role of Gravity in the motion of a Star System.

What space craft has traveled the furthest away from the Earth?
The Voyager 1 - 165.9 AU (24.8 billion km; 15.4 billion mi)
