What is the closest star to Earth?

Explanation:
The main idea is that the Sun is a star, and it is much closer to Earth than any other star. The Moon is not a star; it’s Earth’s natural satellite that reflects sunlight. Other stars, like Proxima Centauri and Sirius, are far away in space—measured in light-years—so they are much farther from us than the Sun. Because distance is what determines “closest,” the Sun is the nearest star to Earth.
