What is most widely accepted today is the giant-impact theory. It proposes that the
Moon formed during a collision between the Earth and another small planet
, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

How was the Moon formed according to NASA?
The moon was likely formed
after a Mars-sized body collided with Earth and the debris formed into the most prominent feature in our night sky
. It is the only celestial a body beyond Earth that has been visited by human beings. … “Year” (time to orbit the Earth): About 27 Earth days. Day: About 27 Earth days.
What evidence is used to support the age of the Moon?
Usually, scientists estimate our moon’s age by using
the radioactive decay of elements like uranium
, says John Chambers, a planetary scientist at the Carnegie Institution for Science in Washington, D.C.
What are 5 facts about the Moon?
- The Moon’s surface is actually dark. …
- The Sun and the Moon are not the same size. …
- The Moon is drifting away from the Earth. …
- The Moon was made when a rock smashed into Earth. …
- The Moon makes the Earth move as well as the tides. …

Can humans inhabit the Moon?
Colonization of the Moon is a concept employed by some proposals of establishing
permanent human
settlement or robotic presence on the Moon, the closest astronomical body to Earth, and the Earth’s only natural satellite.
Is the flag still on the Moon?
Current status. Since the nylon flag was purchased from a government catalog, it was not designed to handle the harsh conditions of space. … A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12,
16, and 17 missions were still standing as of 2012
.
What does NASA say about the Moon?
The Latest. The brightest and largest object in our night sky, 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.
Where is Theia now?
A new study led by Qian Yuan, a geodynamics researcher at Arizona State University (ASU), Tempe, suggests that
the remnants of Theia is still inside Earth
, probably located in two continent-size layers of rock beneath West Africa and the Pacific Ocean. Seismologists have been studying these two rock layers for decades.
Who is older the sun or the moon?
The moon
, researchers now say, likely formed about 50 million years after the solar system did, which is much earlier than the previous estimate of 150 million years after solar-system formation. A German-led group ferreted out the new estimate by studying three rare elements.
How old is our Earth?
Earth is estimated to be
4.54 billion years old
, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
Which is older Earth or Moon?
According to their modeling, it’s
85 million years younger than current
estimates suggest. Scientists have long estimated the moon formed some 4.51 billion years ago when a Mars-sized object (which we’ve since dubbed Theia) smashed into Earth.
How cold is the Moon?
How cold is the Moon? There is almost no atmosphere on the Moon, which means it cannot trap heat or insulate the surface. In full sunshine, temperatures on the Moon
reach 127°C
, way above boiling point.
What if we destroyed the Moon?
Destroying the Moon would
send debris to Earth
, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
Who named the Moon?
Galileo’s discovery. So, why do the moons around other planets have names, while ours is just the moon? When the moon was named, people only knew about our moon. That all changed in 1610 when an Italian astronomer called
Galileo Galilei
discovered what we now know are the four largest moons of Jupiter.
