text: So Earth and Venus are called the "twin planets" but there not that similar because one can substain life and one cant for right now. Venus is rotating around the sun alot faster then Earth and so that is why a year on Venus would be short compared to one on Earth. We have sent many spacecraft/spaceships to venus and successfully made it but its been more than 30 years since that has happen. So the reason for that is Venus has a 97% carbon dioxide "blanket" thats covering the atmosphere and thats why its so much hotter then Earth and is unfit for a human. Specially because of all the nature causes this heat brings like volcanoes and powerful earthquakes along with alot of lightning strikes that go all the way to the surface on venus.
