The planet Venus comes physically closer to us than any other planet in the solar system. The mass of the Venus atmosphere is 96% carbon dioxide, not a human-friendly environment! Carbon dioxide makes up less than 1% of our terrestrial atmosphere. Venus rotates very slowly and seems to have only one tectonic plate. "Venusquakes" happen mush less frequently than Earthquakes. No moon-lit nights on the planet named for the goddess of love, Venus has no moon.
