text: Venus is our "twin" when it comes to different types of features he planet has. Venus is occasionally the closest planet to Earth. Since Earth, Venus, and Mars have different sizes and mass they orbit the sun and different speeds. This means that sometimes Mars is closer to us than Venus at the right time of year. Scientist examine and still want to study our neighboring planet Venus because they belive life couldve been supported on the planet at one point in time and want to know if the planet has had such capabilties.
