The planet, venus is a planet having almost same density and size with earth.
Venus is second planet from the sun, it presents a hostile environment with temperatures soaring to 880 degrees Fahrenheit (471 degrees Celsius) and oppressive surface pressures.
Billions of years ago, the venus had as much water as the earth has but today, venus is extremely hot and without water. Venus water has almost completely been lost.
The solar system has contributed to this loss because venus inhabits the too- hot side of the sun, this affects the amount of energy the planet radiates away.
On early Venus, sunlight broke up water in its atmosphere into hydrogen and oxygen, the hydrogen escapes in a flow out to space, a process called hydrodynamic escape.
This process removed one of the key ingredients for water from Venus.
