Discover how impact craters can provide insight into the history of the solar system in this video from NASA's Goddard Space Flight Center. Scientists compare impact craters that have changed over time with fresh craters to determine how landforms have evolved. The Linne crater on the Moon is a pristine crater ideal for comparison with other craters. The Lunar Reconnaissance Orbiter gathered data about the shape and structure of the Linne crater that provides scientists with the tools to better understand how weather, climate change, and other factors affect the development of landforms.

Explore how astronomers and scientists use astronomical units to measure distances in the solar system in this video adapted from NASA. The astronomical unit (au) -- equal to the average distance from Earth to the Sun -- is a convenient unit of measure when talking about distances in the solar syste
