text: Venus is a identical twin to Earth because Venus in terms of density and size, and occasionally the closesy in distance too. I know this because in the article it says "Earth, Venus, and Mars, our other planetary neighbor, orbit the sun at different speeds." Another reason would be because "scientists disscus further visits to its surface." Final reason is because both Earth and Venus are very identical and scientist plan to expand human life and have people start studying Venus. This is why Earth is identical to Venus.
