The Earth and the Moon form the Earth-Moon satellite system with a shared center of mass, or barycenter. This barycenter is 1,700 km (1,100 mi) (about a quarter of Earth's radius) beneath the Earth's surface. The Moon's orbit is slightly elliptical, with an orbital eccentricity of 0.055. [1]
The Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
2 days ago · The Moon was the first new world on which humans set foot; the information brought back from those expeditions, together with that collected by automated spacecraft and remote-sensing observations, has led to a knowledge of the Moon that surpasses that of any other cosmic body except Earth itself.
As the Moon orbits Earth, different parts are in sunlight or darkness at different times. The changing illumination is why, from our perspective, the Moon goes through phases. During a "full moon," the hemisphere of the Moon we can see from Earth is fully illuminated by the Sun.

Jul 16, 2024 · The move of the rocket stage for Artemis marks the first time since the Apollo Program that a fully assembled Moon rocket stage for a crewed mission rolled out from NASA Michoud. The SLS rocket’s core stage is the largest NASA has ever produced. At 212 feet tall, it consists of five major elements, including two huge propellant tanks that ...
The Moon was likely formed after a Mars-sized body collided with Earth several billion years ago. Earth's Moon is the only place beyond Earth where humans have set foot, so far. Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter ...
Sep 7, 2023 · Studying and understanding the Moon offers valuable insights into the cosmos and our place within it. So, the next time you look up at the Moon, remember that it’s more than just meets the eye.
Jul 9, 2024 · From Earth, it might look like the Moon is changing shape each night – from a tiny sliver to a half moon to a full moon and back again. What’s actually happening is that from our spot on Earth, we see different parts of the Moon lit up by the Sun as the Moon travels in its orbit.
Jul 16, 2004 · The new moon, when the moon is darkened, occurs when the moon is almost directly between Earth and the sun—the sun's light illuminates only the far side of the moon (the side we can't see...
