27. -Virtually the same size, mass and Density as Earth
2. Venus
-Virtually the same size, mass and Density as Earth
-Sun rises in the west and sets in the East because it rotates opposite to Earth
-One day on Venus is about as long as a year on Earth
-Hottest surface because the atmosphere is a thick cloud of CO2 (464° C).
-Rains sulfuric acid
-No oceans, Active volcanoes
-No Moons
-Typically the brightest object in the sky. 27
