Landing on Venus | COSMOS in a minute #45

If you land on the surface of Venus, you would notice something very strange. The Sun won’t be visible at all. That’s because the atmosphere of Venus is so thick and dense that it blocks out all visible light. Instead, sunlight gets scattered, creating a dim, diffused illumination at ground level. But that doesn't make Venus a cold world. Quite the opposite, it is the hottest planet in our solar system, with surface temperatures averaging around 475°C. Also, the thick atmosphere ensures that heat is evenly distributed. Hence, there's almost no temperature variation between the day and night sides. The planet’s slow rotation, with a day longer than a year, blends day and night into perpetual twilight, with no clear distinction between day and night in terms of sunlight. It's a world that defies comparison within our solar system. For more videos of Cosmos in a minute, follow The Secrets of the Universe.
