Because there is a layer of clouds made of carbon dioxide covering Venus, which gather all the heat in, but then don't let any of it out, so Venus becomes super-hot.
Venus is hottest. Next is Mercury.
Jupiter, at the surface anyway. Venus has the hottest surface temperature of all the planets.
Venus is the hottest planet in our solar system. It's the second closest to the sun, and its atmosphere traps heat better than Mercury's. The average temperature on the surface of Venus is 867°F (464°C), which is hot enough to melt lead!
In order, they are Venus, Mercury, Earth, Mars.
Venus
Venus has a surface temperature that falls within the range of 90 K to 700 K. With an average surface temperature of about 735 K, Venus is the hottest planet in our solar system due to its thick atmosphere that traps heat.
There might be a misconception here. Uranus is not the hottest planet; on the contrary, it is the coldest, with the average temperature of -370 F (- 220 C). Venus is the hottest, with an average temperature of 870 F (480 C).
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.
With a temperature of 462 degrees, Venus is the hottest planet.
Venus in the hottest planet in our solar system. It has an average temperature of around 900 degrees Fahrenheit.
A planet called WASP-12b is the hottest planet ever discovered (about 4,000 degrees Fahrenheit, or 2,200 degrees Celsius), and orbits its star faster and closer in than any other known world. The hottest planet in our solar system is Venus, with a temperature of about 900 degrees Fahrenheit, or about 460 degrees Celsius.
