It's because Venus's atmosphere is mostly composed of carbon dioxide, and there are several layers of clouds many kilometers thick of sulfuric acid. The dense atmosphere traps in heat, producing a green house effect that raises the surface temp about 400 degrees; enough to melt lead.
Mercury, on the other hand, has almost no atmosphere, and therefore no way to hold in heat. While the side of Mercury that faces the sun is hot, the side facing away from the sun is actually quite cold, since heat is not held when the planet rotates.

Venus is hotter than Mercury despite being farther from the Sun because of its thick atmosphere made mostly of carbon dioxide, which traps heat from the Sun. This greenhouse effect causes Venus to have an average surface temperature of 462 degrees Celsius, making it the hottest planet in our solar system. Mercury, on the other hand, lacks a significant atmosphere to retain heat, resulting in much greater temperature variations between its day and night sides.

Which planet is closest to the sun why isin't it the hottest planet?
Mercury is the closest planet to the Sun. Despite being the closest, it's not the hottest due to its lack of a significant atmosphere to trap heat. Meanwhile, Venus, the second planet from the Sun, is the hottest because of its thick atmosphere that creates a greenhouse effect.
Is Mars the fourth hottest planet in your solar system?
Yes.Earth is 3rd hottest,Mercury is 2nd hottest, and Venus is the hottest.
What two planets are hottest and why?
The two hottest planets in our solar system are Venus and Mercury. Venus is the hottest due to its thick atmosphere that traps heat, creating a strong greenhouse effect. Mercury is the second hottest because of its proximity to the sun, although it has no atmosphere to retain the heat.
Mercury is hottest planet?
The direct answer to the question is: No.Mercury is the closest planet to the sun, but Venus is the one with thehighest surface temperature, and Neptune is the one with the lowest.
Why is mercury not the hottest?
While mercury is the closest planet to the sun, Venus is actually the hottest planet in our solar system due to its dense atmosphere that traps heat. The thick atmosphere on Venus creates a greenhouse effect, absorbing and retaining much of the sunlight that reaches the planet's surface, leading to extremely high temperatures.
IS Mercury the hottest planet in your solar system?

Is Mercury the hottest planet in space?
Surface temperatures place Venus above Mercury.
What makes Mercury the hottest planet?
Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
Is Mars the fourth hottest planet in your solar system?
Yes.Earth is 3rd hottest,Mercury is 2nd hottest, and Venus is the hottest.
Is the planet closet to the sun the hottest?
No. For example Venus is the second closest planet but is the hottest. This is because it has a thick atmosphere and therefore it holds the heat in more than mercury (the closest planet) does.
If you lived on Venus what can harm you?
Most likely the heat, it is the hottest planet. Not even Mercury is as hot as Venus.
What was the hottest planet of all?
In our solar system, the hottest planet is Venus. Even though the planet is second-closest to the sun, Venus' atmosphere holds in a lot of the heat, making it hotter than Mercury.
What is the hottest planet in milky way galaxy?
It is not known, since we don't know all the planets in the galaxy, but in our solar system Mercury is the hottest planet, since it's closest to the sun. The hottest planet in Milky Way would be some planet closest to the biggest and hottest star there is. that is wrong, venus, due to it's hot surface and acid gases and things like that, make it the hottest planet. Mercury has no atmosphere, and Venus has a large CO2 high pressure atmosphere, hence Venus is hotter than Mercury!
