Venus is the 2nd closest planet to Sol in the Solar System. She is Earth and dead Theia's sister, and Earth's 'twin', as they're both the same size, but not similar at all in sorts of looks and personality. She has an unique feature, which is that she has a retrograde rotation. This means she rotates the other way around regarding Earth's rotation. This is due to a proto-planet smashing into her when she was a baby. She's also the brightest and hottest planet, at roughly 480º C. She was once hospitable to life, but a greenhouse effect erased Venus' life.
Personality
Venus is a self-centered planet, but she cares a lot of Earth, after all, they're sisters. She's sort of jealous of Earth having a moon, which is one of her dreams, but no one knows about her little jealousy yet. Earth suspects that Mercury was once Venus' moon, and got accidentally ejected later, but when Earth asked her about it, she answered "No". Still, Earth is quite sure she lied. Venus is very confident too, and she doesn't like too much to admit her mistakes.
Appearance
Venus is the prettiest planet in the system (as her name says). She is covered with a thick layer of tan clouds. Due to her high temperatures, her surface is boiling, showing an orange color.
