Chapter 1
Our Solar System Overview
Key Concepts
The solar system is a family of objects held together by the Sun’s gravity. Knowing where these objects fit helps you explain space clearly on Florida science tests.
• The Sun is a star at the center of our solar system. - The eight planets travel in paths called orbits around the Sun. - Gravity is a pulling force. The Sun’s gravity helps keep planets in orbit. - Planets do not make their own light. They reflect light from the Sun. - Moons orbit planets. Earth has one moon. - Asteroids are rocky objects. Comets are icy objects that can form bright tails near the Sun. - Stars are huge, hot balls of gas. They are much farther away than planets.
Before you continue: How are a planet, a moon, and a star different?
Key Terms
Solar system - The Sun and all the objects that orbit it.
Star - A huge, hot ball of gas that makes its own light.
Planet - A large, round object that orbits a star.
Moon - A natural object that orbits a planet.
Orbit - The path an object follows around another object.
Gravity - A force that pulls objects toward each other.
Asteroid - A rocky object that travels through space.
Comet - An icy object that may grow a bright tail near the Sun.

Worked Examples
1. Which object is at the center of our solar system?
1. Planets orbit the Sun. 2. The Sun is a star. 3. Therefore, the Sun is at the center.
Now you try: Which object gives Earth most of its light and heat? ________________________________________________ ______________________________________________ ________________________________________________
2. Earth and its moon
1. Earth is a planet. 2. The Moon travels around Earth. 3. Therefore, the Moon is Earth’s natural satellite, or moon.
Now you try: What does our Moon orbit? ________________________________________________ ______________________________________________ ________________________________________________
3. Sort the objects
1. The Sun makes its own light, so it is a star. 2. Mars travels around the Sun, so it is a planet. 3. An asteroid is a rocky space object. 4. A comet is mostly ice and dust.
Now you try: Sort these: Jupiter, a comet, the Sun, and an asteroid. ________________________________________________ ______________________________________________ ________________________________________________
Practice Questions
1. (Easy) Circle the star: Earth, Moon, Sun. ________________________________________________ ______________________________________________ ________________________________________________
2. (Easy) What force helps keep planets in orbit? ________________________________________________ ______________________________________________ ________________________________________________
3. (Medium) Draw an arrow to show the Moon’s orbit around Earth. ________________________________________________ ______________________________________________ ________________________________________________
4. (Medium) Explain why Earth is a planet, not a star. ________________________________________________ ______________________________________________ ________________________________________________
5. (Hard) Name two objects in the solar system and explain how they move. ________________________________________________ ______________________________________________ ________________________________________________
Answer Key
1. Sun. 2. Gravity. 3. The arrow should circle Earth and show the Moon moving around it. 4. Earth orbits the Sun and reflects light; it does not make its own light. 5. Example: Earth orbits the Sun, and the Moon orbits Earth.
Exam Tips & Common Mistakes
• Do not call the Sun a planet. The Sun is a star because it makes its own light. - Do not say planets make light. Planets reflect light from the Sun. - Remember that a moon orbits a planet, while a planet orbits a star. - Draw arrows in the correct direction when showing an orbit. - Use science words such as “orbits,” “gravity,” and “reflects light” in your answers. - Read every choice carefully. Look for whether the question asks about a star, planet, moon, or smaller object. - If you are unsure, cross out choices that mix up the Sun, planets, and moons.
Quick Reference
Rules to remember
• Sun = star at the center. - Planet = orbits a star. - Moon = orbits a planet. - Gravity = pulling force. - Planets reflect sunlight.
Memory clue: S-P-M: Sun, Planets, Moons. The Sun is central, planets orbit the Sun, and moons orbit planets.
The essentials
• Our solar system has the Sun, eight planets, moons, asteroids, comets, and other objects. - The Sun’s gravity holds the system together. - Planets travel in orbits. - Stars make light; planets reflect light. - Moons orbit planets.

For a fun finish, draw the Sun, Earth, and Moon. Add arrows to show how Earth moves around the Sun and how the Moon moves around Earth. Then color each object a different color.
