The Surface Temperature Of Venus Is 730K, Even Hotter Than Mercury
It’s no surprise that Venus is one of the hottest planets in the Solar System. The surface temperature of Venus is a scorching 730 Kelvin (457°C / 845°F). This is much higher than the surface temperature of Mercury, which is around 300K (27°C / 80°F).
That’s because Venus is much closer to the Sun than Mercury. It’s the second planet from the Sun, and it’s just 67 million kilometers away – compared to Mercury, which is 58 million kilometers away. This means that it receives more energy and heat from the Sun, and its atmosphere traps more of that heat than Mercury’s atmosphere can.
Venus’s thick atmosphere is made up of mainly carbon dioxide, which is a strong greenhouse gas. This traps most of the Sun’s energy and heat, raising the temperature of the planet’s surface. In fact, the surface temperature of Venus is around 427°C (800°F) during the day – and a whopping 869°C (1590°F) in its clouds!
Venus’s extreme heat makes it difficult for any kind of life to exist on its surface. There is no water vapor on Venus, and there is no liquid water either. The heat is too much for most organisms, so the planet is completely barren.
However, there may be signs of life underneath the planet’s surface. Scientists have detected sulfur compounds emanating from deep within the planet, which could be evidence of microbial lifeforms. If this is true, then Venus may not be as inhospitable as it seems.
In any case, the surface temperature of Venus is still incredibly high. It’s much hotter than Mercury, and it remains one of the most fascinating and mysterious planets in our Solar System.
