Venus is the sun, its distance from the solar system 's second planet .

 This terrestial planet is often referred to as the "sister planet" of the Earth, because there are great similarities in structural elements and behavior between Earth and Venus.

 This planet is also called Lusifer or Satan  when it rises in the sky of the earth in the morning . Bengal morning sky each morning star and the evening sky each evening to be called. It has no satellites .

The Bengali name for the planet Venus comes from Shukracharya, the guru and protector of the demons , and Friday comes as the day of Venus.

Venus in Latin named after the Roman goddess of love venous (Venus, Latin: uyenus , in English: bhinas ) name. In mythology, Venus (Greek: Aphrodite , Bengali Venus) is the wife of Valkan and the mother of Cupid and Danius.

The English adjective Venus bhenusiyana (Venusian) is used. But the Latin adjective is the uyenereyal (Venereal), English accent bheniriyyal modern English language and sexually transmitted diseases in the negative, as the word is used. 

Venereal for thisThe word is no longer used as an adjective. Many astronomers named the planet adjective sithariyana (Cytherean), which used the term in Greek mythology to the goddess Aphrodite surname sithariya came from. 

There are also a few more adjectives: Venerean (Venerean, Venarian), Veneran (Veneran), etc.

In Chinese , Japanese , Korean, and Vietnamese cultures, the planet is called the metallic star (金星), which is derived from the names of the five basic elements that make up the earth.


Orbit

Although the orbits of all the planets are elliptical, the orbits of Venus are almost round. Its eccentricity is less than one percent.

Since the distance of Venus from the Sun is less than that of the Earth, the Sun rises from the Earth's side (the largest elongation of the Sun is 48.6 degrees) and Venus also rises from almost the same direction.

This is why the planet can be seen only a few hours before sunrise and a few hours after sunset.

Of course, it can also be seen during the day when Venus is in its brightest state. In fact , Venus is the only celestial body without the moon that can be seen from the Earth's sky at both night and day.

However, in some cases, apart from the night and the day can be seen at both. E.g. , crab nebulaeCreative newcomers. However, in the dark sky, Venus shines like a star to show the visible planets.

The duration of the cycle between the two highest echoes is 564 days.

 After these 564 days, Venus is seen to be at an angle of 72 degrees with the position it used to be.

 Since 5 * 574 = 2920 = 8 * 365, it is seen that Venus returns to its previous position every 6 consecutive years (except for two days of leap year). 

This cycle was known in ancient Greek civilization as the Sotheby's cycle and was also well known to the Maya civilization . It also has a relationship with the moon, such as: 29.5 * 99 = 2920.5; This means that this period is equal to about 99 lunar months .

Venus comes closer to Earth than any other planet during the interconnection of the planets; Then the distance of the earth from this is about 100 times the average distance of the earth from the moon .

 Since 1600, Venus has been closest to Earth since December 16, 1850. When was the distance between them: 0.28413854 astronomical unit = 39,541,626 kilometers. This will be the shortest distance from Venus to Earth before December 16, 2101. On that date, the distance between the two planets will be 0.28431736 astronomical unit = 39,541,56 kilometers.


Rotation


Venus has a relatively slow motion , moving east to west where most other planets rotate from west to east.

Of course, Pluto and Uranus also have reciprocal motions.

This slow repulsion of Venus is thought to be caused by tidal forces , friction, and the intense atmosphere of Venus overheating by the Sun. If the sun could be seen from Venus, it would rise in the west of Venus and set in the east.

Its diurnal motion is equal to 117.75 days on Earth and the duration of a Venus year is 1.92 Venus days.

It takes Venus 225 days to complete its orbit around the Sun. Venus rotates on its own axis very slowly.

Venus has a diameter of 12,104 km and a density of 5.06. Its release speed is 7.5 miles per second. Venus has no significant magnetic field . Carbon dioxide is almost all of the planet's atmosphere .

It contains only 0.4 percent oxygen gas. Some nitrogen , hydrogen , ammonia and nominal water vapor have been found on Venus .

So far, many spacecraft have been sent into space to know the news of Venus.

Among them Pioneer , Venus-1 and Venus-2 and Venus 11 to 14 are very important.

Pioneer spacecraft have taken pictures of Venus from which scientists have discovered that Venus has huge mountains, plains and many volcanoes.

A rough map of Venus has been made possible as a result of a careful survey by Pioneer. This spacecraft has sent many pictures of Venus. Venus -14 and 15 landed on Venus and sent wonderful color pictures to Earth. However, before that in March 1967 Venus-3The surface of Venus is wrecked. Scientists think that there is no life on Venus.
