Size comparison of the Sun and the Earth |
Composite photo of the Sun and Earth, showing the difference in size between the two astronomical objects. Although the Sun is an average-sized star, it is so large that its volume is equivalent to 1.3 million Earths and it contains approximately 99% of the total mass of the Solar System.
