Abstract
- New research on lunar chronology has led to a revised understanding of the ages of major lunar features. While radiometric analyses of lunar samples provide the most accurate ages, samples have only been collected from 11 sites. For the rest of the Moon, crater counts are used to estimate ages. However, there are uncertainties in these estimates due to various factors. A new study has proposed three corrective factors that affect cratering rates on the Moon, leading to corrections in the model ages of craters at different locations. This new model will be tested with samples from unexplored lunar regions, such as the upcoming Artemis landing near the Moon's South Pole. The document also provides information on various planets in our solar system, including details about their illumination by the Sun and their distances from Earth. It presents this information in a visually appealing format, with planet disks and orbits depicted. [Extracted from the article]
