Question

How does that affect how the sun and moon appear as seen from Earth? A. The sun appears to be four times the size of the moon. B. The sun and the moon appear to be nearly the same size. C. The full moon appears to be twice as large as the sun. D. The sun appears to be 400 times the size of the moon.

Answer 1

B. The sun and the moon appear to be nearly the same size.

The Sun and the Moon appear to be nearly the same size from the Earth's perspective because the Moon is about 400 times closer to the Earth than the Sun, and the Sun is about 400 times larger than the Moon. This means that the Sun and the Moon appear to have the same size in the sky, which makes possible the phenomenon of a solar eclipse, where the Moon completely covers the Sun. Even though the sun is much larger than the Moon, but its distant location makes it appear small in the sky while the Moon is much smaller but it is much closer to us, that's why they appear to be the same size.
