VENUS - created from Mind Map

Seite 1

Venus is the second nearest planet from the Sun.

Venus is a rocky planet. This means that most of its surface is made up of rocks.

Venus completes an orbit every 224.7 earth days, even though it completes a rotation every 243 Earth days, so a day in Venus is longer than a year.

Its atmospheric pressure at the planet's surface is 92 times the Earth's

It was the first planet beyond the Earth visited by a spacecraft

Venus has several times as many volcanoes as the Earth, and it has 167 volcanoes that are over 100KM across

Its surface is estimated to be about 300-600 million years old

Because of this, even though it's colder than Mercury, which is the closest planet to the sun, Venus has got a temperature of about 462ºC.

Unlike other rocky planets, Venus hasn't got a natural sattelite

Venus rotates in the opposite direction to most planets.

Roughly the Earth's pressure found 900M below sea level

Also the first to be successfully landed on

Studies have suggested that billions of years ago, Venus's atmosphere was like the Earth's

Now, its atmosphere is 96.5% carbon dioxide and the remaining 3.5% is nitrogen

Above the CO2 layer there are thick clouds made of sulfuric acid droplets

Venus Express also discovered in 2011 that an ozone layer somehow exists in the atmosphere of Venus.

These clouds also contain sulfur aerosol, 1% of ferric chloride and some water

Other possible materials of this clouds are ferric sulfate, aluminium chloride and phosphoric anhydryde
