Coincidence that sun and moon – same size?


Is it a coincidence that the sun and the moon are seen to be 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.

So the sun and moon appear nearly the same size as seen from Earth. And that’s why we on Earth can sometimes witness that most amazing of spectacles, a total eclipse of the sun.

No one knows the odds, because no one knows how many planets and moons there are in space. Astronomers have discovered 893 planets in distant solar systems so far (as of June 21, 2013), and we don’t know much about their moons.


A coincidence? Seen nowhere else in our Solar System.

EarthSky asked Myles Standish about the similarity in the size of Earth’s moon and sun, as seen from Earth. He is a mathematical astronomer and a former professor at Yale University. He worked for CalTech’s Jet Propulsion Laboratory. He has published over 300 articles, mostly in the field of solar system dynamics and celestial mechanics. He said this similarity is unique among the planets and moons that make up our local family in space, our solar system. In other words, it doesn’t occur with any other planets and moons in our immediate neighborhood of space.

But there may be millions or billions of undiscovered solar systems.

So what are the odds of the moon and sun appearing nearly the same size from Earth? No one knows.

Bottom line: The sun’s diameter is about 400 times larger than that of the moon – and the sun is also about 400 times farther from Earth. So the sun and moon appear nearly the same size as seen from Earth. What are the odds?

I for one don’t think its a coincidence – it’s a sign from the signs of Allah.

“Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed signs for people of understanding.” [Quran 2:164]

“And He who made the night for rest and sun and moon for reckoning of time. This is the decree of the Exalted, the All-knowing.” (Quran 6:96)

“Among His Signs are the Night and the Day and the sun and moon. Prostrate not to the Sun and the Moon but Prostrate to Allah Who created them if it is Him ye wish to serve.” (Quran 41:37)
