🌍 Sun, Moon & Planets: Exploring Our Amazing Space Neighborhood
Blast off into space to learn about the Sun, the Moon, and the planets that make up our solar system! Discover how they move and why they matter to us on Earth.
Learning Goals
By the end of this lesson, you will be able to:
✓
Describe the Sun, the Moon, and the planets in our solar system
✓
Explain how the Earth and Moon move in space
✓
Identify why the Sun is so important to life on Earth
Before You Start
Before this lesson, you should know:
→
You should know that Earth is the planet we live on
→
You should know that the Sun gives us light during the day
→
You should be able to count and compare sizes, like big and small
Key Space Words
Important words to know for this lesson:
Sun
A giant star made of hot, glowing gas that gives Earth light and warmth. ☀️
Moon
A large rocky ball that circles around the Earth and glows at night. 🌙
Planet
A large round object that moves in a circle around the Sun, like Earth.
Orbit
The curved path one space object takes as it travels around another, like a racetrack in space.
Solar System
The Sun and everything that moves around it, including all 8 planets and their moons.
Our Space Neighborhood
Our solar system is made up of the Sun in the center, with 8 planets and their moons traveling around it in paths called orbits.
The Sun is a star: The Sun is not a planet — it is a huge, hot star. It is so big that about 1 million Earths could fit inside it! It gives us light and heat.
Planets orbit the Sun: There are 8 planets. In order from the Sun they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each one travels in its own orbit.
The Moon orbits Earth: The Moon is Earth's closest space neighbor. It does not make its own light — it shines because it reflects sunlight, like a mirror.
Day and night: Earth spins like a top. When your side faces the Sun it is daytime, and when it faces away it is nighttime. One full spin takes 24 hours.
Example
Think of the Sun as a coach standing in the middle of a field, and the planets as players running around the coach in big circles. Earth is one player, and the Moon is a smaller friend running circles around Earth!
100%
The Sun sits in the center while the planets orbit around it, with Earth's Moon nearby.
Let's Try It Together!
Basic
The Moon takes about 28 days to go all the way around Earth. How many days is that from the start to the halfway point?
Let's Try a Harder One!
Intermediate
Earth takes about 365 days to travel around the Sun one time. About how many days would 2 full trips around the Sun take?
Your Turn to Practice
Try this one yourself — use the hint if you get stuck:
Our Solar System has 8 planets. If you count Earth and all the planets closer to the Sun than Earth, how many planets is that? (Hint: Mercury, Venus, Earth)
In the Real World
🌞
The Sun gives us daylight and warmth, helping plants grow the food we eat.
🌙
The Moon's pull causes ocean tides to rise and fall at the beach.
🗓️
Earth takes about 365 days to go around the Sun — that's why we have one year!
Quick Check

Q1.What is the Sun?
Q2.What moves around the Earth?
Q3.How many planets orbit our Sun?
Challenge Question
Optional
Stretch your brain — this one's a bit harder!
Earth takes 24 hours to spin around once, making day and night. If it is daytime where you live, what is happening on the opposite side of Earth?
Key Takeaways
1.The Sun is a star that gives us light and heat.
2.The Moon orbits the Earth and does not make its own light — it reflects the Sun's light.
3.Eight planets orbit the Sun, and Earth is one of them.
4.Earth spinning gives us day and night, and orbiting the Sun gives us one year.
