Jan 25, 2016

The sun is approximately 109 times the diameter of the earth.

#### Explanation:

The Earth's diameter is 12,742 km
The Sun's diameter is 1391,000 km,
so the sun is 109.17 times the Earth's diameter,
or put another way, the Earth is 0.00916 sun diameters.

In terms of volume, the sun would fit 1.3 million Earths, and in terms of mass, the Sun is $1.99 \times {10}^{30}$kg and Earth is $5.97 \times {10}^{24}$kg, so the sun is approximately 333,000 times as massive as the Earth.
