The sun's trajectory

It is stressed in the Qur'an that the Sun and Moon follow specific trajectories:

It is He Who created night and day and the sun and moon, each one swimming in a sphere. (Qur'an, 21:33)

The word "swim" in the above verse is expressed in Arabic by the word "sabaha" and is used to describe the movement of the Sun in space. The word means that the Sun does not move randomly through space but that it rotates around its axis and follows a course as it does so. The fact that the Sun is not fixed in position but rather follows a specific trajectory is also stated in another verse:

And the sun runs to its resting place. That is the decree of the Almighty, the All-Knowing. (Qur'an, 36:38)

These facts set out in the Qur'an were only discovered by means of astronomical advances in our own time. According to astronomers' calculations, the Sun moves along a path known as the Solar Apex in the path of the star Vega at an incredible speed of 720,000 kmph. In rough terms, this shows that the Sun traverses some 17.28 million km a day. As well as the Sun itself, all the planets and satellites within its gravitational field also travel the same distance.
