What is the term used to describe the star at the center of our solar system?

The term used to describe the star at the center of our solar system is "Sun." The Sun is a massive ball of gas, primarily composed of hydrogen and helium, and it generates energy through nuclear fusion, which produces the light and heat that sustains life on Earth. It is classified as a G-type main-sequence star (G dwarf) in the Hertzsprung-Russell diagram, representing its temperature, luminosity, and evolutionary stage.

In contrast, a planet is a celestial body that orbits a star and does not produce its own light, a meteor refers specifically to the bright streak of light produced when a meteoroid enters the Earth’s atmosphere, and an asteroid is a small rocky body that orbits the Sun, primarily found in the asteroid belt between Mars and Jupiter. These other terms refer to different types of celestial objects that do not encompass the characteristics of the star at the center of our solar system.
