I’m so pretty, but: You can look, but you better not touch! Named after the Roman Goddess of Love and Beauty, I am the brightest object in the night sky (except the Moon). Earth is my twin in terms of size and it is closer to me than to any other Planet. But there our similarities end: I am the only planet to rotate backwards, and very slowly, so a day lasts longer than my year! Carbon dioxide makes me the hottest planet in the Solar System. I’m hot enough to melt lead!
