The temperature at the surface of Venus can reach a scorching 464°C (867°F). This makes it the hottest planet in our solar system, even hotter than Mercury, which is closer to the sun.

However, it's important to note that this temperature is measured at the surface. Venus has a very dense atmosphere, composed primarily of carbon dioxide, which creates a powerful greenhouse effect. This traps heat and causes temperatures to rise significantly higher in the upper atmosphere.

In fact, the temperature at the top of Venus's clouds can be as low as -40°C (-40°F), making it a much more manageable environment in terms of temperature.

So, while the surface of Venus is incredibly hot, the upper atmosphere has a much cooler temperature.
