Let's review what we've learned about our solar system

Our Solar System

• We live on the planet Earth, 3rd planet from the Sun

• Our Solar System is a system of celestial bodies (planets, asteroids, stars, etc.) that orbit around the star (rarely can be 2 stars at the center).

Analogy

• The Earth is like our house

• Our solar system is like our neighborhood

• Our galaxy is like our country

• The Universe is like the entire world

Multiple Choice

Which of the following keeps planets in our solar system in orbit around the Sun?

• frictional force

• gravitational force

• atmospheric force

• kepler force

Multiple Choice

What does the word "revolve" or "revolution" mean?

• same thing as "orbit"; to spin

• same thing as "orbit"; one object traveling around another object

• same thing as "orbit"; to move unpredictably

• same thing as "orbit"; to move due to gravity

Multiple Choice

A major feature of the solar system is that as planets get farther away from the Sun, they:

• are warmer

• are smaller in diameter

• have a longer revolution time

• reduce in mass

Multiple Choice

A lightyear is a measurement of

• time

• distance

Multiple Choice

Which planets have a greater distance between them; the inner planets (Mercury, Venus, Earth, Mars) or the outer planets (Jupiter, Saturn, Uranus, Neptune)?

• inner planets

• outer planets

Multiple Choice

Which of the following CORRECTLY lists the planets in order from closest to the Sun to the farthest away from the Sun?

• Mars, Venus, Mercury, earth, Saturn, Uranus, Jupiter, Neptune

• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

• Neptune, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Mercury
