Detailed explanation-1: -Our Sun is a medium-sized star with a radius of about 435, 000 miles (700, 000 kilometers). Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330, 000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume.

Detailed explanation-2: -The Sun appears so large compared to the other stars because it is so much closer to us than any other star. The Sun is just an average sized star. For example, below is a list of some of the largest stars in our galaxy and how they compare to our Sun: Mu Cephi-about 1500 times the size of our sun.

Detailed explanation-3: -The Sun is considered a star because it emits heat throughout the universe. Its temperature can reach 5500 °C on the surface. Despite being such a large star in size, the Sun is a medium-sized star, as there are stars larger than it.

Detailed explanation-4: -The mean radius of the sun is 432, 450 miles (696, 000 kilometers), which makes its diameter about 864, 938 miles (1.392 million km). You could line up 109 Earths across the face of the sun, according to NASA (opens in new tab). The sun’s circumference is about 2, 715, 396 miles (4, 370, 006 km).

Detailed explanation-5: -Our Sun is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of our solar system. The Sun is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet.
