Such tidal interactions also have consequences for our planet's oceans, which are tugged by the moon's gravity to regularly rise and fall in sequences we call tides.

It gains its light from the sun, which reflects light off its surface toward Earth. 15 November 2019. Zoom Earth shows live weather satellite images updated in near real-time, and the best high-resolution aerial views of the Earth in a fast, zoomable map. As the space doughnut re-cooled, material at its outer edges coalesced into small "moonlets" and eventually the moon itself. The leading theory for the moon's formation suggests that it came into existence roughly 4.5 billion years ago, not long after the solar system was born, which occurred about 95 million years earlier. Moon dust is made from extremely sharp and tiny pieces of volcanic glass that have been smashed out of the lunar soil by micrometeorites. The moon shines bright in Earth's night sky, reflecting light from the sun. Future US, Inc. 11 West 42nd Street, 15th Floor, (25,000 kilograms) — about the same weight as a loaded dump truck. Scientists are still scratching their heads over how it formed. Some astronomers have proposed tweaks to this hypothesis, such as the possibility that proto-Earth was turned into a doughnut of molten rock called a synestia after Theia vaporized our planet. Please refresh the page and try again. The Latin word for our satellite is Luna — the English word "lunar" is derived from it. Today, researchers know these areas were carved from the moon's crust billions of years ago when lava flowed over the lunar surface. Online Planetarium Our Online Planetarium allows to compute the coordinates of planets, comets and asteroids and visualize them in the sky with respect to stars and constellations. Receive mail from us on behalf of our trusted partners or sponsors? In Greek, Selene is the name of a mythical moon goddess, giving us the word "selenology," or the study of the moon's geology.

The moon's atmosphere is known to contain argon-40, helium-4, oxygen, methane, nitrogen, carbon monoxide, carbon dioxide, sodium, potassium, radon, polonium and even tiny amounts of water. Explore recent images of storms, wildfires, property and more. The thin lunar atmosphere means these fragments hardly ever erode and so dust on the moon is caustic, clogging the equipment and zippers Apollo astronauts brought to the moon, as well as probably being rather toxic for human health.

The moon is our constant companion and Earth's only consistent natural satellite. Water molecules detach from the surface of the moon when it gets too hot and float to colder areas of its surface and thin atmosphere. The moon is one-fourth our planet's size but has a lower density, meaning that gravity is only 0.17 times as strong on the moon as it is on the surface of Earth. The moon looms large in the sky, the second brightest object after the sun. Apollo astronauts also brought back 842 lbs. Thank you for signing up to Live Science.

An even stranger theory suggests that Earth's gravitational pull allowed it to steal the moon from early Venus. The picture is rendered by computer and displays the Earth now with its current illumination and the bright and the dark sides of the Earth. On the lunar far side is the South Pole-Aitken Basin — an impact hole 1,550 miles (2,500 km) wide and 8 miles (13 km) deep that is among the oldest and deepest of the moon's many blemishes. In comparison, the Earth's atmosphere at sea level has around a billion billion times more molecules per cubic centimeter. Whatever its origin story, the moon has been with us throughout human history, gaining names in ancient languages. Some of these elements came from outgassing as the moon cooled. (Image credit: NASA's Goddard Space Flight Center/Scientific Visualization Studio). By Low tides occur at times between these two points. Its relatively small core makes up just 1% to 2% of its mass and is roughly 420 miles (680 km) wide.

The moon orbits an average of 238,855 miles (384,400 km) from our planet — a close enough distance that gravitational forces have tidally locked it to Earth, meaning the same side always faces us, according to NASA.
