Venus
The planetarium has over 2,500 images! >> GO!
Venus is similar to Earth in mass and size. But likeness ends here! This is the hottest world in the solar system where temperature is hot enough to melt lead at 800 degrees Farenheit. The surface pressure is the same as being 3000 feet under Earth's oceans. Venus is the only planet to rotate backwards so you the sun would rise on the western horizon. Like Mercury, a day on Venus is longer than a year. One day is 243 Earth days while one year is 225 days. The surface of Venus is about 500 million years old with low lying plains and large mountains. The interior of the planet is quite similar to Earth.
