NASA Astronomy Picture of the Day 28 February 2023: Moon and the Temple of Poseidon
The Moon has long been a central focus of Earth-related studies, playing a significant role in a range of phenomena, such as tides. Whether for religious, cultural, or purely scientific reasons, the full Moon holds great importance for many people. Scientists believe that the Moon formed approximately 4.5 billion years ago, shortly after the solar system took shape. NASA suggests that a massive object called Theia, about the size of Mars, collided with Earth at this time, resulting in the formation of the Moon. To date, the Moon remains the only place beyond Earth that humans have visited to date.
