Venusis a smoldering hottie! Venus has the highest surface temperature of any planet in our Solar System due to thick clouds that trap in heat. Im so pretty! But while you can look, you had 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 that is where our similarities end: I am the only planet to rotate backwards, and very slowly, so a Venusian day lasts longer than my year! An atmosphere made mostly of carbon dioxide traps heat and makes me the hottest planet in the Solar System. more than 800 degrees F. Im hot enough to melt lead!
