![]() ![]() ![]() The Moon and Space Exploration: The Moon plays a crucial role in human space exploration.The Moon, in conjunction with the Sun, causes high and low tides, an effect that has significant implications for marine life and human activities. Additionally, the Moon's gravitational pull affects Earth's oceans, causing tides. The Moon orbits Earth about once every 27.3 days, and as it does, the angle at which sunlight hits it changes, causing the visible portion from Earth to cycle through phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Moon Phases and Tides: Understanding the phases of the Moon is a crucial aspect of astronomy. ![]() In terms of structure, the Moon has a thin crust, a mantle, and a small, partly molten core, similar to Earth but much less geologically active. A popular theory is the Giant Impact Hypothesis, which suggests that a Mars-sized body, referred to as Theia, collided with Earth, and the debris from this collision eventually coalesced to form the Moon. It's believed that the Moon was formed about 4.5 billion years ago, shortly after the formation of the Solar System.
