Our Local Star
Our Local Star is a Grade 5 science concept from Amplify Science (California) revealing the Sun as simply the nearest star to Earth — the center of our solar system and the only star located within it. All other stars are outside the solar system and appear as tiny points of light because of their enormous distances. Covered in Chapter 1, this concept shifts students from seeing the Sun as unique to understanding it as a typical star that only appears special because of its proximity, building the framework for comparing stellar distances and apparent brightness.
Key Concepts
It might be hard to believe, but the Sun is a star, just like the tiny points of light in the night sky. The Sun is the center of our solar system , a neighborhood in space that includes Earth and other planets.
The Sun is special to us because it is the one and only star inside our solar system. All other stars are located far outside this system. This makes the Sun our local star , while all others are distant neighbors.
Common Questions
Is the Sun a star?
Yes, the Sun is a star — specifically, it is our local star, the one located inside our solar system. It is the same type of object as the thousands of stars visible in the night sky. It appears much larger and brighter than other stars only because it is much closer to Earth.
What makes the Sun different from other stars?
The Sun is not physically unique — it is an average-sized, medium-temperature star. What makes it special to us is its location: it is inside our solar system, about 93 million miles away, while all other stars are trillions of miles away outside our solar system.
What is our solar system?
Our solar system is a collection of planets, moons, asteroids, and other objects that orbit the Sun. The Sun sits at the center and its gravity holds everything in the system together. All eight planets, including Earth, orbit within this system.
How far away is the Sun compared to other stars?
The Sun is about 93 million miles from Earth. The next nearest star, Proxima Centauri, is about 4.24 light-years away — roughly 25 trillion miles. The nearest other star is about 270,000 times farther away than our Sun.
When do 5th graders learn that the Sun is a star?
This concept is covered in 5th grade science. Amplify Science California Grade 5 Chapter 1 introduces the Sun as Earth's local star while investigating why we can't see other stars during the day.
Why do other stars look like tiny dots compared to the Sun?
Other stars look like tiny dots because they are incredibly far away. The same star that appears as a bright point of light from Earth would look as large and bright as our Sun if we were close to it. Distance makes all the visual difference in apparent size and brightness.
Which textbook introduces the Sun as our local star in 5th grade?
Amplify Science (California) Grade 5 Chapter 1 introduces the Sun as a star — specifically our local star inside the solar system — while exploring why daytime astronomy is limited by the Sun's overwhelming apparent brightness.
