Sun's Orbit in the Qur'an

idbc wrote: "Why does the Quran say that the sun has an orbit, when we know it doesn't?"

I suspect idbc is referring to either of the following verses:

"And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit." (21:33)

"It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit." (36:40)

We all know that the moon has its own orbit, revolving around the earth; however, the sun has its own orbit as well...around the galactic center, which is estimated to take about 225-250 million years for one "cosmic year."

The Qur'an is correct, yet again.
