The Sun has a mean radius of about 432,450 miles (696,000 kilometers), giving it a diameter of approximately 864,938 miles (1.392 million kilometers)
. This means the Sun is about 109 times wider than Earth, and roughly 1.3 million Earths could fit inside it by volume
. Its circumference is about 2.7 million miles (4.37 million kilometers)
. The Sun's mass is about 333,000 times that of Earth, containing 99.86% of the total mass of the Solar System
. Although the Sun is the largest object in our Solar System, it is considered an average-sized star compared to other stars in the galaxy, with some stars being hundreds of times larger
. In summary:
- Diameter: ~1.39 million km (864,938 miles)
- Radius: ~696,000 km (432,450 miles)
- Circumference: ~4.37 million km (2.7 million miles)
- Size relative to Earth: 109 times wider, 1.3 million Earth volumes fit inside
- Mass: 333,000 times Earth's mass, 99.86% of Solar System mass
This makes the Sun an enormous and dominant presence in our Solar System
