That's not quite right! The Sun is much larger than the Moon. Here's why:

* Diameter: The Sun's diameter is about 1.4 million kilometers, while the Moon's diameter is about 3,474 kilometers. This means the Sun is about 400 times wider than the Moon.

* Volume: The Sun's volume is about 1.3 million times greater than the Moon's volume.

So, the Sun is significantly larger than the Moon, not just 40 times larger.
