Planets of our Solar System: Venus

here it comes here it goes, post about planet just little smaller than Earth with atmosphereVenus in approximately true colour, a nearly uniform pale cream, although the image has been processed to bring out details.[1] The planet's disc is about three-quarters illuminated. Almost no variation or detail can be seen in the clouds. so dense that… well it is very very dense.

But first things first: Venus is second planet from Sun. It is sometimes called “The Evil Twin of Earth”. It is rotating around its axis in the opposite direction from other planets which means that Sun rises there on the west and sets on the east. It is rotating extremely slowly so its day is longer than its year (224:243).
Because of this Venus is also most round planet of all planets in solar system, because no strong centrifugal force is expanding planet at the equator.

Venus is third brightest object on the sky after Sun and Moon. She is easy to see right after sunset and before sunrise.

Even that Venus is 110 000 000 km away from the sun she is hotter then Mercury because of its extremely dense atmosphere which is creating tremendous greenhouse effect (and also pressure which is over 60x greater than our). It is possible that in the past there was water on the surface but positive feedback of greenhouse effect did fast process with it. Now over 95% of Venus´s atmosphere is made up by carbon dioxide. Surface temperatures can rise to over 450°C.

Because of so thick atmosphere it was not possible for long time to observe her surface but now thanks to radars we know that there are over 100 000 volcanoes and 167 of them have diameter greater than 100 kilometers. Structures here are named after women or goddesses from different cultures.

Scientists are not really sure why but sometimes there are holes in the atmosphere through which we can see “down”. Every 100 years or so happens the transit of Venus over Sun. It happens in pairs which are 8 years apart and those who missed it as me are very unlucky since next one will be in the year of 2117 (it is so rare because Venus´s orbit is
moved by 3° so it is usually “above” or “below” us.)

  1. I recommend to look at Venera mission (by Soviets in eighties) which brought first pictures of the Venus surface. Also interesting thing about Venus is that there are speculations that its clouds could host extraterrestrial life…

    • I will definitely look up Venera, thank you very much! Well yes there are some speculations maybe but on the other we know that clouds there are too acidic, they are made up of sulfuric acid which is probably not really good for any kind of live. But i will check it too, not really sure so lets hear their arguments!
