What is the size of Venus?
|Venus is 12,104 kilometres/7,521 miles across. It is slightly smaller than Earth which is 12,756 kilometres/9,926 miles across.|
|Is Venus bigger than Mercury?||Yes, Venus is bigger than Mercury. Mercury has a diameter of 4,878 km, Venus has a diameter of 12,104 km.|
|What is the number of rings around Venus?||There are no rings (or even moons) around Venus.|
|How far is Venus away from the sun compared to Earth?||Venus orbits the Sun at an average distance of 108,160,000 kilometres (67,000,000 miles). Earth orbits the Sun at an average distance of 149,600,000 kilometres (92,960,000 miles). Although this means there is a distance of over 4 million kilometres between the two planets, they are the two closest planets in the Solar System.|
I am studying Venus in school (2nd grade) and used your website for some research. I liked learning about the Magellan Mission. One thing I have learned from school is that the pressure on Venus is so strong that it could crack a ship. When the Magellan ship orbited Venus for 4 years, why didn't it break apart as other ships would have? I am really looking forward to finding out more!
|Thanks for visiting my website and using it for your research. In answer to your question, the pressure on Venus is so strong that it would crush any object on its surface. However, when the Magellan space craft visited Venus, it stayed in orbit around the planet at a safe distance and took radar images of Venus to allow us to map the surface of the planet. Although Venus' surface pressure is great, the planet's pull of gravity is similar to Earth's so a satellite can be put into orbit around the planet and remain there just like a satellite around Earth. At the end of its mission on 11th October 1994, the space craft was purposely dropped out of orbit around Venus so it fell into the planet's atmosphere. It either burnt up during its descent through the atmosphere or was crushed by the planet's pressure when it reached the surface.|
