Why doesn’t the Moon completely block the Sun during an annular eclipse?
A
The Moon is a little farther away, so it looks smaller
B
The Moon’s shadow doesn’t complete land on the Earth
C
The tilt of the Moon’s orbit is too high
D
The size of the Sun increases
Explanation: 

Detailed explanation-1: -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. During a total solar eclipse, the Moon passes between Earth and the Sun. This completely blocks out the Sun’s light.

Detailed explanation-2: -The reason is that the Moon’s orbit around the Earth is tilted relative to the Earth’s orbit around the Sun.

Detailed explanation-3: -The Moon does not completely disappear as it passes through the umbra because of the refraction of sunlight by the Earth’s atmosphere into the shadow cone. The amount of refracted light depends on the amount of clouds or dust in the atmosphere blocking the light.

Detailed explanation-4: -A solar eclipse occurs when the Moon passes between the Sun and Earth, casting the Moon’s shadow on Earth. A solar eclipse can only happen during a New Moon. The Moon’s orbit is titled 5 degrees to Earth’s orbit around the Sun.
