1. • • When the Moon is about 400 times closer to Earth than the Sun, the Moon's and the Sun's apparent sizes roughly match. Because of this, total eclipses of the Sun can only occur when the Moon is near perigee—it is the only time when the disk of the Moon looks big enough to cover the entire disk of the Sun.

   Is the Moon bigger than the Sun?

   • In reality, many of those stars are larger than our Sun—they are just much farther away from Earth! Even though the Moon is 400 times smaller than the Sun, it's also about 400 times closer to Earth than the Sun is. This means that from Earth, the Moon and the Sun appear to be roughly the same size in the sky.

   Why is the Sun 400 times wider than the Moon?

   • It is a coincidence that the sun is 400 times wider but also 400 times farther than the moon. Both of them fluctuate in apparent size due to the elliptical orbits of the Earth and moon (hence the "supermoon" phenomenon), and sometimes the moon won't appear big enough to block the entire sun and you get an annular eclipse.

   Why do the Sun and Moon appear the same size?

   • The sun and moon appear the same size in Earth's sky because the sun's diameter is about 400 times greater - but the sun is also about 400 times farther away. Learn more on EarthSky.

   Does the moon cover the Sun?

   • In this case, the Moon obscures most of the Sun, but a thin ring of the Sun remains visible around the Moon. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

   May 3, 2020 · The reason why the ISS keeps its relative size against both the Sun and the Moon is due to a remarkable coincidence: the diameter of the Moon is 400x smaller than the diameter of the Sun, but it is also 400x closer to us!

   Mar 29, 2024 · The Short Answer: The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective.

    Total eclipse begins (2nd contact): The Moon covers the entire disk of the Sun, and observers are now within the Moon's umbra, the darkest part of the Moon's shadow. A diamond ring effect and Baily's beads are visible just before totality.
