Question

What makes our sun a star?

Answer 1

Sun as a star

1. Our Sun is a medium-sized star.
2. The gases like hydrogen and helium make up the Sun. Nuclear fusion keep on going at multimillion-degree temperatures in its massive core, and it also provides energy to the sun.
3. On the Sun, dark splotches are common. Sunspots are places on the surface of the sun where magnetic fields are concentrated. The sun is often referred to as a "common" star.
4. The Sun's outer layers rotate at varying rates: at the equator, the surface rotates once every $25.4$ days, while at the poles, it rotates once every $36$ days.
5. About $4.5$ billion years have passed since the birth of the Sun. It has depleted around half of the hydrogen in its core since its inception. The Sun is orbited by eight planets and a slew of minor bodies.
