2 de dez. de 2022 · An enduring myth about the Moon is that it doesn't rotate. While it's true that the Moon keeps the same face to us, this only happens because the Moon rotates at the same rate as its orbital motion, a special case of tidal locking called synchronous rotation.
Há 1 dia · Check today’s Moon phase with our 2024 Moon Phase Calculator. You can see what the Moon looks like tonight and every day of the month! We highlight the four main lunar phases: New Moon, First Quarter, Full Moon, and Last Quarter Moon, along with when they occur.
Several theories about our Moon’s formation vie for dominance, but almost all share that point in common: near the time of the solar system’s formation, about 4.5 billion years ago, something ― perhaps a single object the size of Mars, perhaps a series of objects ― crashed into the young Earth and flung enough molten and vaporized debris into space to create the Moon.
Half of the Moon’s surface is always illuminated by sunlight. However, just how much of that light we can see from our point of view on Earth varies every day and this is what we refer to as a Moon phase.
Visualize, explore, and analyze the lunar surface using real data returned from a growing fleet of spacecraft. View the Moon through the eyes of many different instruments, pilot real-time 3D flyovers above mountains and into craters, and conduct measurements of surface features.
How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth’s Moon. Since it was named before we learned about other planetary satellites, it is called simply “Moon.” According to the NASA/JPL Solar System Dynamics team, the current tally […]
