Here are the key points:
* Solar radiation at the top of Venus's atmosphere: About twice as much as Earth's.
* Surface sunlight: Very little reaches the surface due to the thick clouds.
* Surface temperature: Despite the high solar radiation, Venus's surface is incredibly hot due to the greenhouse effect, reaching around 464°C (867°F).
So, while Venus receives a lot of sunlight, very little actually makes it to the surface, making it an incredibly hot and inhospitable place.
