Venus' atmosphere is similar to Earth's as it has one predominant gas. Venus' is comprised of mainly Carbon Dioxide, around 96%. Whereas Earth's atmosphere is mainly Nitrogen, around 78%. Both atmospheres contain levels of other gases but the main difference is the presence of Oxygen on Earth, around 21%.

Gravity on both planet's is very similar. Measured at the equator, Earth's gravity is 1g or 9.81NKg-1 , the SI unit for gravitational field strength. Venus' gravity is around 0.9g or 8.87NKg-1
