The Sun is an average star on the Orion Arm of the Milky Way galaxy and the closest star to Earth. It is a main sequence star roughly half way through its lifetime. Its mass provides over 99% of the total mass of the solar system.
At the center of our solar system is a star, the Sun. The Sun is an average-sized star about halfway through its life cycle. It is a near-perfect sphere of plasma that emits radiation due to nuclear fusion reactions taking place. Nearly three-quarters of the Sun’s mass is its main nuclear fuel, hydrogen. When the fusion reactions take place, two hydrogen nuclei combine together to form a helium atom. This reaction produces a large amount of energy.
The Sun is essential for life on Earth as it provides heat and light energy for green plants to photosynthesize. The Sun accounts for over 99% of the mass in the solar system. Our Sun is a main sequence star that has remained stable for roughly four billion years and will remain stable for about another five billion years. After five billion years, the Sun’s supplied of hydrogen will run out and the Sun will expand. It could expand to swallow the orbits of Mercury and Venus, it could even encompass the Earth. Even if it doesn’t reach our home planet, the increase on surface temperatures would make life on Earth impossible.
It is not an especially large star, there are many more like it. The Sun is a part of a larger body of stars known as a galaxy. Our galaxy is called the Milky Way, it is a group of billions of stars orbiting a supermassive black hole. The Sun provides a gravitational force which binds our solar system together; every planet, rock and dust that orbits it does so because of the forces associated with the Sun’s mass.

Model the steps by showing students how to cut a large yellow circle and add rays around it. Encourage creativity in their designs!
Discuss key Sun facts as students work
Share interesting facts about the Sun’s size, temperature, and importance to Earth while students assemble their models. This reinforces learning through hands-on engagement.
Display finished Sun models and review what was learned
Showcase student creations on a bulletin board or classroom wall. Guide a discussion to recap Sun facts and what students enjoyed about the activity.
Frequently Asked Questions about The Sun: Fun Facts for Students
What is the Sun?
The Sun is a massive, glowing ball of hot gas at the center of our solar system. It provides light and heat to Earth, making life possible.
How does the Sun help life on Earth?
The Sun gives us energy in the form of sunlight, which plants use to grow through photosynthesis. It also keeps our planet warm enough for people, animals, and plants to survive.
Why is the Sun important for students to learn about?
Learning about the Sun helps students understand weather, seasons, energy, and how all living things depend on the Sun to survive.
What are some interesting facts about the Sun for kids?
Some fun facts: The Sun is about 93 million miles from Earth, it's over 100 times wider than our planet, and it takes about eight minutes for sunlight to reach us!
How can teachers use pictures to explain the Sun in class?
Teachers can use pictures to show the Sun's size, its position in the solar system, and how sunlight travels to Earth, making lessons more visual and easy to understand.
