What is the following is true about our Sun?

The Sun is a nearly perfect sphere of hot plasma, primarily composed of hydrogen (about 74%) and helium (about 24%). It generates energy through nuclear fusion in its core, where hydrogen atoms fuse to form helium, releasing immense amounts of energy in the process. This energy is what provides light and heat to our solar system, making life on Earth possible. Additionally, the Sun is classified as a G-type main-sequence star (G dwarf star) and is approximately 4.6 billion years old.
