30 apr 2018 · The moon and sun are both bright round objects in the sky. Indeed, viewed from the Earth's surface, both appear as similarly sized disks. That said, however, they are otherwise very different. The sun is a star, while the moon is a large mass of rock and dirt.

The diameter of the Sun is 1,390,000 kilometers (864,000 miles) and its average distance from the Earth is 1.496×108km (93 million miles). The diameter of the Moon is 3475 kilometers (2159 miles) and it averages 384,400 kilometers (238,900 miles) from Earth. So, the Sun is about 400x larger than the Moon and 400x further away.
But, the Sun and Moon don’t usually appear exactly the same size in the sky. Two factors cause this: First, the Moon does not have a constant distance to the Earth. At its furthest distance (apogee) it averages about 363,400 kilometers away from Earth. At its closest approach (perigee) it is 405,500 kilometers away. A full moon at perigee is a “sup...
When the two elliptical orbits place the Moon and the Sun at just the right distance and orientation relative to the Earth, the two bodies appear the same size and a total eclipse of the Sun occurs. During a total solar eclipse, the Moon completely obscures the disc of the Sun. If the Sun and Moon were always the same relative size, all solar eclip...
Moons form via multiple processes, but they aren’t typically the same apparent size as a planet’s star. For example, consider Mars and its moons. Phobos and Deimos both appear quite a lot smaller than the Sun in the Martian sky. While the Sun is farther from Mars than it is from Earth, the big difference is that the moons are tiny. None of the othe...

ISBN 978-0-19-953209-4.The main differences between the Sun and Moon is that the Sun is the central entity in our solar system that all objects in its local region orbit, has a diameter of 1.39 million km and is the brightest entity in our solar system that produces energy for life to exist via nuclear fusion whilst the Moon is a gray rocky spherical natural satellite...
Shedding Light on Lunar Science. Studying the Sun’s effects helps us to understand the Moon better. For example, when the Sun sets and night falls on the Moon, some spots cool down faster than others. These temperature variations hint at the rocks that lie on the lunar surface.
