text: One way we know exploring Venus is a good idea. Is the fact that Venus is a dead ringer for earth. Their apperance is uncanny just by looking at them. Venus and Earth are really similar plants, they are even nicknamed twins. Earth's size is extremely close to Venus's size. The fact that these planets share a similar size can help infer that they work and sustain themselves similiar. For example, if two people are the same size they probably have similar needs. Their caloric, water, nutrient, and other needs are probably the same. Knowing more about Venus can help the Earth be a healthier place.
