Things get weird when we talk about a Venusian day though. How long is a year there? What about a day?Ī year on Venus takes around 225 Earth days. Seeing as we don’t currently have zeppelin-style habitats here on Earth, the technology would have to be developed. That means we would have to set up habitations in the atmosphere. While we do have underwater vehicles capable of maintaining pressure 1,600 meters below the surface, they don’t do it for long, certainly not long enough to set up a permanent habitat. For even more perspective, free divers stick to about 20 meters below the surface while nuclear submarines go as deep as 300 meters. That’s equivalent to the pressure a mile, or 1,600 meters, underwater. The pressure on Venus’ surface is extraordinary, 90 times that on Earth’s surface. Running from west to east across the center of the image is part of a wide lava channel in the Lada Terra region of Venus. This NASA Magellan radar image mosaic is of part of Venus, centered at 51 degrees south latitude, 21 degrees east longitude. Venus’ atmosphere consists mainly of carbon dioxide, with clouds of sulfuric acid droplets. A deep canyon is named for Diana, Roman goddess of the hunt. A volcanic crater is named for Sacajawea, the Native American woman who guided Lewis and Clark’s exploration.
At the surface, the rocks are different shades of grey, like rocks on Earth, but the thick atmosphere filters the sunlight so that everything would look orange if you were standing on Venus.Īlmost all the surface features of Venus are named for noteworthy Earth women - both mythological and real.
The surface is a thin crust of rock that bulges and moves as Venus’ mantle shifts and creates volcanoes.įrom space, Venus is bright white because it is covered with clouds that reflect and scatter sunlight. Above that is a mantle made of hot rock slowly churning due to the planet’s interior heat. It has an iron core that is approximately 2,000 miles (3,200 kilometers) in radius.
