The degree of hotness of a planet does not depend on as much on closeness to the sun as on its atmosphere.Carbon dioxide has the tendency to absorb heat which in turn increases the temperature. Mercury's atmosphere does not contain carbon dioxide, because of which all the heat is returned to space....

Love teaching and sharing my knowledge with others

The atmosphere of venus is made of co2 which is a green house gas which means the heat from the sun enters but gets trapped in and so an oven like situation is created with raised temperature. ...

We can understand this with reference to glass house effect. Suppose there is a room which is not closed and is near fire and there is another glass room which is little farther from the fire compared to the open room. Now, heat is entering the open room more but also its getting escaped. However,...

We can understand this with reference to glass house effect. Suppose there is a room which is not closed and is near fire and there is another glass room which is little farther from the fire compared to the open room. Now, heat is entering the open room more but also its getting escaped. However, what ever heat entering the glass room, its trapped. hence, the temperature of the glass room is much more than the open room even though the open room is closer. same is the story with Mercury and Venus. Even though Mercury is closer to Sun, it is not trapping the heat as it lacks Carbon di oxide in its atmosphere. On the other hand, Venus has higher percentage of Carbon di Oxide, therefore is trapping more heat and hence it is the hottest planet. Hope this answers your query. Regards Smita read less

Venus is a different story. Its atmosphere is primarily composed of carbon dioxide - the primary green house gas -, which acts like a one-way door. The solar heat enters, but it cannot leave. Thus, an oven is created. This is why Venus has no water. Pictures suggest that Venus once had an aqueous environment,...

Mercury's atmosphere does not have carbon dioxide (CO2) whereas Venus's atmosphere does. CO2 has a high tendency to absorb heat. So for Mercury, the heat is reutrned to space while for Venus the heat is absorbed, which raises its temperature, making it the hottest planet.

It is because venus has the thickest atmosphere in our solar system. The atmosphere consists of green house gases like carbon dioxide, nitrogen which traps more heat.

Venus contains large % of CO2 so it is hottest planet.
