The planet Venus is called the sister planet of Earth because it resembles the Earth in many ways but also different in many properties. The structure and size of the planet Venus are similar to the planet Earth. The difference lies in the temperature and composition of the atmosphere. The temperature of Venus is much larger than planet Earth and sufficient to melt lead. The atmosphere of Venus is so dense that the atmospheric pressure is 90 times the atmospheric pressure on Earth. The equivalent pressure on Earth exists in the oceans at the depth of 1 km. Continue reading “Reasons for excessive amount of Carbon Dioxide in the atmosphere of Venus”

How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?

The solar wind is composed of high energy charged particle which when interact with planetary atmosphere causes degradation to the atmosphere. The Magnetosphere of planet protects the atmosphere of the planet from these solar winds by deflecting charged particles. For example, the planet Mars has no planetary magnetic field to protect its atmosphere from the solar wind which results in continuous loss of atmosphere to space. The planet Venus is much closer to the Sun Continue reading “How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?”

Can you imagine a temperature at which lead melts? Venus is the planet where such a high temperature exists. Although Venus is not the nearest planet to the sun but still it is the hottest planet in our solar system, hot enough to destroy any space probes in very little time. The temperature of Venus is around 471 degree Celsius whereas the temperature of Mercury is 466 degree Celsius in the day, in spite of being the nearest planet to the sun.

How do Venus and Mercury act as Morning and Evening star?

Most of the people whenever to look towards night sky; they try to find out the brightest star in the sky. If you also had tried the same then you must have observed that the brightest star in the sky can be viewed only during evening or morning.
