Planet Venus
Venus - the second planet from the Sun, that rotates around its axis in 243 sublunary days. this can be the longest amount of rotation among all the planets within the system and rotates within the other way from most different planets (which implies that the Sun rises within the west and sets within the east).
Venus has no natural satellite. the earth is called when the Roman divinity of affection and wonder. when the moon it's the second presumably object within the night sky.
Venus could be a planet of sublunary kind, and it's referred to as the "sister of our planet" due to its mass and size. However, it primarily differs from the planet as it has the densest atmosphere of 4 planets of terrestrial cluster that contains quite ninety-six you look after CO2. The gas pressure on the planet's surface is ninety-two times beyond the Earth's, constant pressure is compared with the pressure at a depth of 900 meters underneath the water. Venus is that the hottest planet within the system with a median surface temperature of 462° C, whereas Mercury is that the nighest to the Sun. Venus is shrouded in dense clouds of vitriol.
Dimensions of Venus
With a radius of half-dozen,052 kilometers, Venus is nearly the image of the scale of the planet - solely slightly smaller. From a median distance of 108 million klicks, Venus is zero.7 astronomical units from the Sun. astronomy unit (abbreviated a.u.) - distance from the planet to the Sun. light-weight overcomes distance from the Sun to Venus for six minutes.

The orbit and rotation of Venus
Venus revolves around the Sun at a median distance of zero.72 a.u. (108 million km) and makes one revolution in 224.7 days. once Venus is between the planet and also the Sun, it approaches the planet at a median distance of forty-one million klicks.
Venus revolves around its axis in 243 days. this can be the slowest rotation of all the planets in our system. Since Venus rotates too slowly, Venus Day lasts longer than a year (243 vs. 224.7 sublunary days). Venus rotates around its axis at a speed of half-dozen.52 km/h, whereas the planet at a speed of one,669.8 km/h.
The atmosphere of Venus could be a layer of gases close to the earth. It consists primarily of CO2. The surface temperature is 467°C and also the pressure is nine.3 MPa (900 m deep ocean pressure). The atmosphere of Venus supports continuous clouds of oil of vitriol, that makes it not possible to watch the optical surface on the bottom and in orbit. geography data was obtained specifically mistreatment microwave radar representational process.
Separated from the surface layers, the atmosphere is during a state of monumental circulation. The winds within the higher layer reach a speed of quite a hundred m/s and move sixty times quicker than the rotation speed of the earth. The quickest winds on Earth are solely 100 percent to twenty of the rotation speed.
