Mar 30, 2018

#### Explanation:

What is bigger? can bi interpreted as:

1. Which is more massive?
${M}_{E a r t h} \approx 6 \cdot {10}^{24} k g$
${M}_{S u n} \approx 2 \cdot {10}^{30} k g \approx 300 , 000 \cdot {M}_{E a r t h}$

2. Which have bigger volume or radius?
$V = \frac{4}{3} \pi {R}^{3}$
${R}_{E a r t h} \approx 6400 k m$
${R}_{S u n} \approx 7 \cdot {10}^{5} k m \approx 110 \cdot {R}_{E a r t h}$

The Sun is much bigger than the Earth.

The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth.

The Sun weighs about 333,000 times as much as Earth.

It is so large that about 1,300,000 planet Earths can fit inside of it.
