TOXIC TWIN OF EARTH, VENUS

 

 VENUS (evening star or morning star)

 Venus is the second planet from Sun. It is the brightest star in the evening sky. So, it is also called evening star or morning star. 

This planet has the hottest climate. It is burning like a furnace. Its temperature is 475 degrees Celsius, the temperature at which lead melts. This temperature is due to a high concentration of carbon dioxide in its atmosphere.

 The toxic twin of Earth Venus

Venus is called Earth's twin because it is similar in size and density to Earth. It is the closest planet to Earth.

 However, Venus is not Earth’s identical twin, because it cannot support life on it. 

It has an atmosphere but its atmosphere has poisonous gases in high concentration. Of these gases, one is Carbon dioxide and the other is Sulphuric acid.

 The atmospheric pressure on Venus is too high that it can Crush you. Its pressure has crushed its mountains.

 It can be called Earth's toxic twin because of its poisonous atmosphere in which sulfuric acid forms the cloud of this planet's atmosphere. A high concentration of carbon dioxide in its atmosphere holds heat similar to the greenhouse effect on earth, making it the hottest planet of the solar system. Its atmosphere has a stinky smell like rotten eggs due to the presence of sulfuric acid.

Its sulphuric acid and dust clouds reflect most of the solar radiation, making it the brightest object in the night sky second only to MOON. 

Carbon dioxide does not allow the heat from Venus to escape

 Fun facts about Venus

It has some similarities in size and density to that of earth.

 It rotates opposite to that of earth.  It rotates from east to west. So, the sun rises in the West on Venus.

 Its day is longer than its year.  As it rotates in 243 Earth days on its Axis, however, its Revolution around Sun is completed in 225 Earth Days. Venus’s day is longer than Venus's year.

It is the hottest planet in the solar system although it is far away from the sun in comparison to Mercury still its atmospheric temperature is 475 degrees Celsius, because the carbon dioxide concentration is high in its atmosphere.  The greenhouse effect is very evident on this planet which raises its temperature.

 Mercury on the other hand has no environment as being closer to Sun its environment is blown off by solar winds so, Mercury cannot hold the infrared rays that escaped from its surface.  Further, it does not have a mass strong enough that it can hold the atmosphere.

 Venus's surface is uneven due to the presence of volcanoes, mountains. It has a Rocky surface.

 There is no life on Venus but its cloud may have some microorganism, however, it is not still proven. Its rocky surface is quite new, only 1.5 million years old, that is it has resurfaced itself.
