Thick clouds containing sulfuric acid hide the rocky surface of Earth’s “sister” planet. The atmosphere of Venus is mostly carbon dioxide, which traps heat—causing the surface temperatures to be about 450° C (840° F). Venus shows phases when viewed with a telescope because it is closer to the Sun than the Earth. When seeing part of its unlit side, it presents a crescent or gibbous shape, much like our Moon.

Our Solar System

Our solar system is located on the edge of a spiral arm called Orion’s Arm, and is one-half to two-thirds of the way (28,000 light-years) from the center of our Milky Way galaxy.
