The Sun is primarily made up of plasma, which is a superheated state of matter where electrons are stripped from atoms, creating a mixture of ions and electrons.

Here's a breakdown of the Sun's composition:

* Hydrogen (H): About 70.6% of the Sun's mass is hydrogen.

* Helium (He): About 27.4% of the Sun's mass is helium.

* Other Elements: The remaining 2% includes trace amounts of heavier elements like oxygen, carbon, neon, iron, and others.

While the Sun is not entirely plasma, it's the dominant form of matter within its core and throughout most of its volume.
