Why is Venus hotter than mercury

Why is Venus hotter than mercury


The planets in our solar system are different in many ways. Some planets are gas giants, while others are small and rocky. Some planets are close to the sun, while others are far away. And some planets are hotter than others.

Venus is the hottest planet in our solar system. Mercury is the second-hottest planet in the solar system. Let's look at why Venus is hotter than Mercury, despite the fact that Mercury is closest to the sun.

The surface temperature of Venus is about 475 degrees Celsius. The surface temperature of Mercury is about 430 degrees Celsius.

There are several reasons why Venus is hotter than Mercury. 

Venus is near to the sun

The first reason is that Venus is near to the sun; not as close as Mercury, but close enough for Venus to be hotter than Mercury. Venus is around 0.7 AU away from the sun, whereas Mercury is about 0.6 AU away.

Venus's atmosphere is thicker than Mercury

The second reason is that Venus's atmosphere is thicker than Mercury's. Venus's atmosphere contains 96 percent carbon dioxide, but Mercury's atmosphere is so thin that it is non-existent, and since Venus has a thicker atmosphere, it captures more heat from the sun than Mercury, which has a very thin atmosphere.

Venus has a greater albedo

Venus has a greater albedo than Mercury, which is the third reason. The amount of light reflected back into space by a planet is measured by its albedo. Venus has an albedo of 0.75, but Mercury has an albedo of only 0.12. Venus is brilliant because it is surrounded by highly reflecting clouds. The clouds in Venus's atmosphere contain sulfuric acid droplets as well as acidic crystals floating in a gas mixture. The flat surfaces of these spheres and crystals allow light to bounce readily off them.

Conclusion

In conclusion, there are several reasons why Venus is hotter than Mercury. Venus is closer to the sun, has a thicker atmosphere, has a higher albedo. These factors all contribute to the high surface temperature and average surface temperature of Venus.
