The Sun is significantly larger than Earth in every physical dimension:

  • Radius: The Sun’s radius is 109 times greater than that of Earth.12
  • Mass: The Sun is 330,000 times more massive than Earth. Its mass is so immense that it accounts for more than 99 percent of the total mass of the entire solar system.12
  • Volume: In terms of volume, the Sun is more than a million times larger than Earth.1
  • Surface Area: The Sun’s surface area is approximately 12,000 times that of Earth.1

Despite these vast differences, the Sun appears to have a similar angular size in the sky to the Moon because of the immense distance separating it from Earth.2
