Figuring out actual size of Planet Earth in comparison to the Sun is quite simple.
First we need to figure out the ratio of both Earth and the Sun and multiply the ratio of their volumes 3× times the answer.
For example, just so we are clear on this we take the Sun’s diameter 1,392,000 and divide it by Earth’s 12,756 diameter, equalling 109.1.
We then multiply 109.1×109.1×109.1, resulting in a ball park number of approximately 1,300,000.km
Approximately 1.3 million Earth’s able to fit inside the G2 Star.
