Vocabulary
Tool used by scientists to study far away planets that they can't see with just their own eyes.
Telescope
The Hottest Planet.
What is Venus?
The Moon is a satellite of Earth. The Moon's surface has large craters where meteors have crashed into it. Why does Earth NOT have similar craters?
This phase is when the moon is more than half full.
What is Gibbous Moon

What is the Milky Way Galaxy?
This unit is used to measure the size of a galaxy.
Light-year
Large planets in our solar system made of gas are called this.
Gas Giants
In space.
This phase is when the moon is less than half full.

Asteroids, Comets, Moons and Planets
This is a synonym for something that orbits earth.
Satellite
The gravity that holds the planets in an eclipse orbit comes from this.
What is the sun?
The bright streak of light that we call a shooting star is actually

The moon is getting bigger and light is growing from the right side so it is in this stage.
The evidence that supports the scientific theory the Bing Bang Theory.
The observation of galaxies getting further apart (or expanding).
The now most believed model where the sun is the center of the solar system.
Heliocentric Model
Smaller, Rocky Planets in our solar system are called this.
Terrestrial Planet

Read the Passage:
The idea that Earth was not the center of the solar system was not a popular one until the sixteenth century, when scientist Nicolaus Copernicus put out his book "On the Revolution of Heavenly Spheres." In his book, Copernicus explained that he thought the Sun was the center of the solar system, not Earth. It took time for other scientists to believe in his idea, but modern scientists have been able to prove it by taking satellites into space and taking many pictures of the solar system.
Since Copernicus did not have satellite pictures, what did he most likely use to make other scientists believe his explanation about the solar system?
A. the math that he used as evidence for his explanation
B. a map detailing the motion of nearby constellations
C. the drawing he made of Earth from his mind
D. a story about how he thought up his idea
the math that he used as evidence for his explanation
