No, the Earth and the Sun are not the same size. The Sun is much larger than the Earth.

Here's a comparison:

* Sun: Diameter of about 1.39 million kilometers (865,000 miles)

* Earth: Diameter of about 12,742 kilometers (7,926 miles)

That means the Sun is about 109 times wider than the Earth.

To put it in perspective, you could fit about 1.3 million Earths inside the Sun!
