.:the sun's orbit:.

Ancient people use to believe around the earth . Later, Nicolas Copernicus in1512, laid his Heliocentric Theory of Planetary motion, which placed the sun motionless in the center of the solar system with all the planets revolving around it .Modern science tell us now that the sun too is not still , but is in motion

The sun travelling at roughly 150 miles per second takes about 200 million years to complete one revolution around the center of our Milky Way Galaxy and 25� days to make one complete rotation around its own axis. See how beautifully and accurately God revealed this phenomenon in the Quran.

�It is He who created the night and the day, and the sun and the moon, all (celestial bodies) swim along , each in its orbit with its own motion. The Noble Quran, 21:33
