The Hottest Planet - Venus

Venus is the hottest planet in our solar system. It has a surface temperature of approximately 462 °C (864 °F), which is hotter than the surface temperature on Mercury, the closest planet to the sun.

Reasons why Venus is the hottest planet:

1. Greenhouse Effect: Venus has a thick atmosphere that is primarily composed of carbon dioxide. This carbon dioxide traps heat from the sun, causing the planet's surface temperature to rise.

2. Proximity to the Sun: Although Venus is not the closest planet to the sun, it is closer than Earth. The closer proximity to the sun means that Venus receives more solar radiation, which can contribute to the planet's high temperatures.

3. Slow Rotation: Venus rotates slowly, taking approximately 243 Earth days to complete one rotation. This means that one day on Venus is longer than one year on Venus. The slow rotation means that the planet's atmosphere is not evenly distributed, with the atmosphere on the dark side of the planet being cooler than the atmosphere on the sunlit side.

In conclusion, Venus is the hottest planet in our solar system due to its thick atmosphere, proximity to the sun, and slow rotation.
