We learn from the Quran that:
“By the sky full of paths and orbits.”
(The Quran, 51:7)
The entire universe is full of paths and orbits. The Quran also tells us that:
“(Allah is the) One who created the night , and the day, and the sun and the moon, swim along, each in its (own) orbit.” (21:33)
“It is not permitted to the sun to overtake the moon, nor can the night outsrip the day, each swims along in its (own) orbit.” (36:40)
While referring to the Sun and the Moon in the Quran, it is emphasized that each moves in a certain orbit. There are about 200 billion galaxies in the universe, consisting of nearly 200 billion stars in each. All celestial bodies including planets, satellites of these planets, stars and even galaxies swim along their own orbits.
It is mentioned in another verse, too, that the Sun is not static but moves in a definite orbit.
“The sun runs on its fixed course for a term (appointed); that is the decree of the All-Mighty, the All-Knowing.” (Yaseen 36:38)
According to the calculations of experts on astronomy, the Sun is travelling at an enormous speed of 150 miles per second. It means that the sun travels roughly 12,960,000 miles a day!
The fact that this information was present in the Quran long before it was discovered by the mankind is yet another testimony that Allah, the All-Knowing, and the All-Wise is the source of this knowledge.
