Explain why the sun and moon appear to be the same size even though the sun is much larger.
 A The sun appears smaller next to the larger moon. B The moon is closer to the Earth than the sun. C The moon revolves faster than the earth. D The sun and the moon are the same distance from Earth.
Explanation:

Detailed explanation-1: -The sun and the moon are about the same size when you look at them in the sky, though that’s just thanks to the coincidence that the sun is about 400 times farther away than the moon and also about 400 times bigger. Another fun coincidence is that the radius of the sun is about twice the distance to the moon.

Detailed explanation-2: -If the Sun and Moon were always the same relative size, all solar eclipses would be total solar eclipses. Instead, sometimes the Moon is a bit smaller than the Sun and annular eclipses occur. In an annular eclipse, the Moon doesn’t fill the whole disc of the Sun, resulting in a bright ring.

Detailed explanation-3: -That means the Sun’s at least five times further than the Moon, and at least five times larger, too… which makes it bigger than the Earth, and at least a million miles (1.6 million km) away.
