How big is the sun compared to other stars?

The sun is considered a medium-sized star, much smaller than some of the massive stars in the universe. When compared to those massive celestial bodies, the sun might seem small, but it's still among the largest objects in our solar system. The size of the sun is an exciting topic for astronomers, and many have been fascinated by the colossal entity that has been nurturing life on earth for billions of years.

The size of the sun can be determined by its mass, volume, and density. With a mass of 1.99 x 10^30 kg, it's the most massive object, while its volume of about 1.41 x 10^18 km3 makes it possible for about 1.3 million earth to fit inside it. The sun's density is about 1.4 g/cm³, which is relatively low, and it's considered a middle-range star in terms of density. When compared to other stars, such as Betelgeuse or UY Scuti, the sun might appear tiny, but it's still a beautiful and essential part of our universe.
