What is the deepest crater on the Moon?
the South Pole-Aitken basin Stretching 1,550 miles (2,500 kilometers) wide and 8 miles (13 km) deep, the South Pole-Aitken basin, as the tremendous hole is known to Earthlings, is the oldest and deepest crater on the moon, and one of the largest craters in the entire solar system.
Why does moon have many craters?
One reason the moon has craters because it gets hit by objects, small pieces of rocks that come from outer space. These are pieces of asteroids, comets that are flying around in the solar system. When they hit the surface, there's an impact. The moon has no atmosphere, and so even a tiny rock will create a crater.
What are 5 facts about the moon?

How many craters are on Mars?
While only about 120 impact craters have been identified on Earth, scientists estimate that on the surface of Mars, there are more than 43,000 impact craters with diameters greater than 5 kilometers (3 miles), and probably over a quarter of a million impact craters that are similar in size to Meteor Crater.
What’s the largest crater on Earth?
the Vredefort crater The largest impact crater on Earth, the Vredefort crater in South Africa, is 99 miles (160 km) wide and was likely created about 2 billion years ago, according to NASA's Earth Observatory (opens in new tab).
How hot is the Moon?
Taking the Moon's Temperature Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.
Is there a dark side of the Moon?
In reality it is no darker than any other part of the Moon's surface as sunlight does in fact fall equally on all sides of the Moon. It is only 'dark' to us, as that hemisphere can never be viewed from Earth due to a phenomenon known as 'Tidal Locking'.
What are the GREY spots on the moon?
Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they're actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth.
How old is the moon?
4.53 billion yearsMoon / Age The moon is a very old soul, it turns out. A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
How cold is the moon?
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
How hot is the moon?
Taking the Moon's Temperature Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.
What crashed into Mars?
When NASA Lost a Spacecraft Due to a Metric Math Mistake. In September of 1999, after almost 10 months of travel to Mars, the Mars Climate Orbiter burned and broke into pieces.
How many craters are on Jupiter?
On the giant gas planets, Jupiter, Saturn, Uranus, and Neptune, we do not see any craters because there is no visible solid surface for the meteors to hit.
What crater killed the dinosaurs?
Chicxulub crater UPDATE: Today, scientists published their first results from a drilling expedition into Chicxulub crater, the buried remnants of an asteroid impact off the Yucatán Peninsula in Mexico that killed off the dinosaurs 66 million years ago.
How big was the crater that killed the dinosaurs?
It was formed slightly over 66 million years ago when a large asteroid, about 10 kilometers (6.2 miles) in diameter, struck Earth. The crater is estimated to be 180 kilometers (110 miles) in diameter and 20 kilometers (12 miles) in depth.
Does it rain on moon?
The moon has a very thin atmosphere so it cannot trap heat or insulate the surface. There is no wind there, no clouds, no rain, no snow and no storms, but there is “day and night” and there are extreme differences in temperatures depending on where the sun is shining.
How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
Are there human remains on the Moon?
To date, the late scientist Eugene Shoemaker is still the only person whose remains have been sent to the Moon. Even casual stargazers are likely to recognize Shoemaker's name from the famed Comet Shoemaker-Levy 9 (which had broken into fragments) that impacted Jupiter in 1994.
Can we hear any sound on Moon?
There is no atmosphere on the surface of the Moon. Sound cannot travel without a medium. Hence, there is no sound on the Moon.
Why are footprints on the Moon still there?
Unlike on Earth, there is no erosion by wind or water on the moon because it has no atmosphere and all the water on the surface is frozen as ice. Also, there is no volcanic activity on the moon to change the lunar surface features. Nothing gets washed away, and nothing gets folded back inside.
Does moon have a dark side?
In reality it is no darker than any other part of the Moon's surface as sunlight does in fact fall equally on all sides of the Moon. It is only 'dark' to us, as that hemisphere can never be viewed from Earth due to a phenomenon known as 'Tidal Locking'.
Will the moon hit Earth?
Short answer: Technically it's possible that the Earth and Moon could collide in the very distant future, but it's very unlikely. It's certainly not going to happen while any of us are alive. Long answer: The Moon is in a stable orbit around Earth.
How long is 1 year on the Moon?
27 daysMoon / Orbital period
What planets have humans landed on?
Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars.
Who bought land on Mars?
Well, a man in West Bengal claims to have bought one-acre land on the red planet and he also has a 'deed' showing the purchase. Shaunak Das states that he has purchased land on Mars from an American website. He also claims that he has purchased a one-acre area of land on Mars.
Does it rain diamonds on Jupiter?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. In fact the planets have the capability to create 1000 tonnes of diamonds a year.
Does Mars have craters?
The Martian surface contains thousands of impact craters because, unlike Earth, Mars has a stable crust, low erosion rate, and no active sources of lava. So, impact craters on Mars are not obliterated as they are on Earth.
Did any dinosaurs survive the meteor?
Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago.
