The twin planets...

The Earth and Venus are not twins.

⏺One of them wrapped herself in a thin quilt. The other was a thick quilt, and that separated them.

⏺ An hour of time in which a person is free, contemplating what God has done with Venus, the brightest object in the sky, an hour in which there is as much worship as a thousand rak’ahs of what those who kneel count.

There is no one who does not know that the solar family has the sun in its middle, and around the sun the nine planets revolve, the closest to the sun being Mercury, followed by Venus, then Earth, followed by Mars, then Jupiter, then Saturn. Saturn was the last of the planets discovered by the ancients, and they had seven of them. Therefore, Al-Ma'arri said:

Saturn is the most honorable of the planets
From meeting the response to the appointment

Then more recent people revealed Uranius and Pluto. Thus, the number of planets was nine.

- The twins:

Scientists called the planet Venus and the planet Earth, our planet on which we live, the twins.

This is because their distances from the sun are similar: Venus is about 67 million miles away from it, and Earth is about 93 million miles away.

The diameter of Venus is 7,700 miles, while the diameter of the Earth is about 7,927 miles.
The mass of Venus is close to the mass of Earth, equal to about 80 percent of it.

The average density of Venus is 4.86, while the average density of Earth is 54.

Venus revolves around the sun and takes its course
224,701 days, while the Earth revolves around the sun, so it takes 365,256 days to complete the revolution.

The Earth has gravity, and this gravity retained an atmosphere for the Earth, holding on to it, and it held on to it. Likewise, Venus has gravity, which preserved an atmosphere for it, just as the Earth did.

From all these facts came the meaning of the twinship that brought together Venus and Earth.
This famous ancient French writer, Bernard Fontenelle, was even tempted to say:
(I can say from here... Who are the inhabitants of Venus? I see them as a people with small bodies, black faces, burned by the heat of the sun, in them is intelligence, and in them is the fire of love that ignites them. They write poetry, and sing to music, in constant celebration, dancing and endless debates. ).

The proximity of Venus to the sun was not the only thing preventing life:

It's all a lover's imagination.
All this similarity tempts this imagination. Or at least he is tempted to have people on Venus like people on Earth.

Even Venus' proximity to the sun would not have prevented this. That is, as long as the intensity of the heat prevents it. We know that the intensity of light and heat, and other similar radiations, decreases with distance from the source of heat and light. If one body was one hundred miles away from the sun, and another body was two hundred miles away from it, the square of one hundred would be 10,000, and the square of two hundred would be 40,000. Therefore, the intensity of heat on the farthest body would be a quarter of its intensity on the nearest body, 10,000/40,000. This is the well-known law, and we have known the distance of Venus from The sun, and what is beyond the Earth. In application of this law, the intensity of the sun’s heat on Venus must be about twice its intensity on the Earth.
This is not an obstacle to life on Venus.

(Venus, the brightest object in the sky, is seen by the eye in the sky, in the evening, as it sets after sunset, or seen by the eye, in the sky, in the morning, and it has preceded the sun in rising, and the eye sees it only as a dot of light. As for a telescope, it sometimes sees it as a crescent, and sometimes Full moons, and everything in between, depending on their position in relation to the sun and the Earth, just as the moon appears to an observer from the Earth, or as the Earth is seen by an observer looking at it while he is in one of the planets, or as the astronaut finally saw it while he was in a spacecraft.)

(Venus disappoints those who look at it with a telescope, because the sunlight that reaches it, which is twice as much as it reaches the Earth, is absorbed by its atmosphere and this prevents seeing what is underneath it. Thus, Venus appears as if there is fog over it. And the attached pictures, the two of which are on the right, are photographs of Venus taken in X-rays without The red ones, and the two on the left, were taken with ultraviolet light.)
