Venus

Venus is the second planet from the sun, and the hottest of them all. It's also really bright from Earth, the third-brightest object in the sky. Venus also doesn't have any moons. Here's a fun fact: A Venus day is longer than a Venus YEAR! Um, you probably already know that. Anyway, another cool thing is that the air is 92 times heavier than on Earth, enough to crush you into a human pancake. Some people say that Venus was once habitable, but then got that runaway greenhouse effect from the Sun warming up and it turned into a lava planet.
