How many planets mentioned in various holy books?

Answer 1

I can only speak for one Holy book, the Holy Bible. As far as I know , no planets are mentioned in the Holy Bible, primarily because at that time the science had not been developed to have the planets named.

Answer 2

The Planets

The planets do not have their own light and revolve, like the earth, around the Sun. While one may presume that others exist elsewhere, the only ones known are those in the solar system. Five planets other than Earth were known to the ancient astrologers: Mercury, Venus, Mars, Jupiter and Saturn. Three have been discovered in recent times: Uranus, Neptune and Pluto.

The Qur'an seems to designate them by the word kaukab (plural kawakib) without stating their number. A good definition of the meaning of the word kaukab in the Qur'an seems to have been given in a very famous verse of Sura ‘Noor”:

"God is the light of the heavens and the earth. The similitude of His light is as if there were a niche and within it a luminary. The luminary is in a glass. The glass is as if it were a planet glittering like a pearl." (24:35)

Here the subject is the projection of light onto a body that reflects it (glass) and gives it the glitter of a pearl, like a planet that is lit by the sun. This is the only explanatory detail referring to this word to be found in the Qur'an. In the following verse:

We have indeed adorned the lowest heaven with an ornament, the planets (14:37)

We come to know about heavenly bodies, which are called as planets. The expression 'lowest heaven' is likely to mean the 'solar system'. It is known that among the celestial elements nearest to us, there are no other permanent elements apart from the planets, the Sun being the only star in the system that bears its name.

The Qur'an further states that Allah created the sun, the moon, and the planets, each with their own individual courses or orbits. "It is He Who created the night and the day, and the sun and the moon; all (the celestial bodies) swim along, each in its rounded course" (21:33).

Answer 3

Does it matter?

Going to a holy book to get your science, any science, is total folly.
