How Big Actually the SUN is.

The Sun is a massive, incredibly hot ball of gas and plasma at the center of our solar system. Its size is quite impressive:

Diameter: The Sun's diameter is about 1.39 million kilometers (about 864,000 miles). To put this into perspective, you could fit about 109 Earths side by side across the Sun's equator.

Volume: The Sun's volume is about 1.41 x 10^18 cubic kilometers. That's over a million times the volume of Earth.

Mass: The Sun's mass is approximately 1.989 x 10^30 kilograms. This is about 333,000 times the mass of Earth. The Sun's immense gravity holds the entire solar system together.

It's important to note that the Sun is considered an average-sized star. While it might seem huge to us, there are much larger stars in the universe, some of which are hundreds or even thousands of times larger than the Sun.
