Venus

 Venus is the second planet of the solar system. It is also known as earth twin, morning star and evening star and it’s also known as the jewel of the sky. It is only planet which rotates clockwise. The properties of venues are far while the density is similar to the earth as in the presence of atmosphere. The atmosphere of Venus is very poisonous and the surface of Venus has only been photographed by the venire probes. It is very different from the earth because it has no oceans and its surrounded has heavy atmosphere composed by carbon dioxide with virtually no water vapor and its cloud are composed of sulfuric acid droplets. The thick clouds lock the heat while the surface rages with active volcanoes. The surface of Venus is often described as a stormy desert full of many craters and very active volcanoes.

History

Venus is believed to be discovered by Galileo Galilee in 1610 and his crude telescope realized that the Venus goes through the moon. Venus is one of the five classical plants that visible to the naked sky and the second brightest celestial object in the night sky but only the moon outshine. Solar system formed 4.568 billion years ago from the gravitational collapse of a region with a large molecular cloud.  For thousands of years she had fascinated curious views from the scholars of antiquity and modernity to mere mortal poets. Edmond Halley realized in 1705 that repeated sightings of a comet were recording the same object returning regularly once every 75-76 year. This was the first evidence that anything other than the planets orbited the sun. In roman mythology Venus is the god of love, beauty and fertility but she was the roman counterpart to the Greek Aphrodite. In Greek mythology Venus is the god of victory, fertility and even prostitution. But the Maya civilization given high regards to the Venus and they should be printing the figure of Venus in her own calendars. Ancient Egyptians were thinking that Venus is actually two separate objects a morning star and evening star. The early mathematician Pythagoras was one of the first recognizer which recognizes that morning star and evening star is a same object.

Composition

Venus is a terrestrial planet in the solar system and it has no moon. The composition of Venus is similar to the earth with a core of metal, a mantle of liquid rock and its outer crust is made of solid rock but Venus is often referred to earth because it’s have same size, mass, gravity and overall composition. The surface temperature of Venus is 462^.c and its average orbital period is 126,074 km/h. The interior of Venus is losing as much heat as the earth and they could be the reason of Venus doesn’t have magnetic field. The equatorial circumference is 38,025 km and its radius is 6,052 km. The surface of Venus is hot enough to melt lead and no spacecraft have survived on the surface for longer than a few hours. The one big difference between our Venus and earth are the lack of plate tectonic in Venus but some another reason plate tectonics on Venus shut down billions of year ago. The solar day length is 117 earth days   and its year length is 225 year days. Venus has an iron core as same size around the earth at approximately 3,000 km. The most earth like atmosphere in the solar system occurs 30 to 40 miles above the surface of Venus. Both oxygen and hydrogen rise above the heavier gas layer covering the ground and the pressures are similar to our planet. Roughly two third of the Venusians surface is covered by flat or smooth plains that are marred by thousands of volcanoes and six mountainous region make up about one-third of the Venusians surface.

Relation With Solar System

The distance between Venus to sun is 108.2 million km and the radius of the sun is 6051.8 km. But the distance between earths to Venus is 101.44 million km. Although Venus is not the closest planet to the sun, its dense atmosphere traps heat in runway version of the greenhouse effect that warms the earth. The sun occupies 10% volume of sphere with radius but earth volume is roughly one millionth that of the sun. Venus is very unusual planet because it spins the opposite direction of earth and most other planet. And its rotation is very slow because it takes about 243 earth days to spin around just once. The Jupiter is the largest planet of which 5.2 AU from the sun and it has a radius of 0.00047 AU. The atmosphere is heavier than the other planet leading to a surface pressure that over 90 times that of the earth and similar to the pressure that exists 3,300 feet deep in the ocean.

Some Amazing Facts

1. Venus completes its one revolution in about 226 days and one rotation in about 243 days. Thus its one day is longer than its one year.

2. It is known as the most erect planet as it has a tilt of just 3 degrees on its axis.

3. It is the only planet which rotates clockwise.

4. It is the second brightest object in the night sky after moon.

5. The atmospheric pressure of Venus is about 90 times than that of the Earth.

6. The air of Venus is so acidic that a single blow of air of Venus can turn a living man into a skeleton.
