The atmosphere of Venus is mostly carbon dioxide, which traps heat -- causing the surface temperatures to be about 460°C (860°F)
A Venusian year (orbital period) is about 225 Earth days long, while the planet's rotation period is 243 Earth days, making a Venus day about 117 Earth days long.
Study of climate change on Venus might answer important questions about important issues such as global warming and climate change here on Earth.
