What Size Was The Object That Collided With Earth When It Was Still Forming?
Many objects collided with Earth during its formation, ranging in size from dust grains to small planets. The one believed to be responsible for the formation of the moon was about the size of Mars.
Who did earth once collide with?
We believe that the proto-Earth, very early in the formation of our solar system, probably collided with another planet, one that might have been as large as Mars. The collision probably entirely re-formed the resultant Earth, and that the heavy metallic cores of both planets merged. Debris blasted into space by the collision probably coalesced to form the Moon.
What are two possibLe reason why the atmosphere on Mars is so thin?
It may have gradually lost its atmosphere to the solar winds or a body or bodies that collided with mars
What collided with earth in the mesozoic era?
A meteor hit the earth in the mesozic era
How many planets is Mars away from the earth?
earth is 1 planet away from mars
Did Mars hit Earth?
No. Mars and Earth never collided. Around 4.6 billion years ago another planet is believed to have collided with Earth, resulting in the formation of the moon. This planet, known as Theia, was probably about the same size as Mars.

What was the name of the Mars sized planet that collided with the Earth and formed the Moon?
Theia See related link for more information.

What is the giant impact theory?
The giant impact theory proposes that the Moon was formed from debris created when a Mars-sized body collided with Earth early in its history. This collision would have ejected material into space that eventually coalesced to form the Moon. This theory is supported by evidence from lunar samples and computer simulations.
How did terestrial planets get moons?
Earth's moon is believed to have formed when Earth collided with a Mars-sized planetoid soon after it formed. Debris from the collision formed a ring around Earth and coalesced into the moon. Scientists still disagree about the origins of Mars' moons Phobos and Deimos. The most prevalent hypothesis is that they are captured asteroids.
How did the moon get where it is?
Before life existed on Earth a Mars like object collided with our planet. A big chunk of the Earth floated away from our planet due to the pressure of the collision. And that big chunk is now what we call, the Moon.
How was the moon really formed?
The moon formed when a Mars-sized planet collided with Earth when the solar system was still forming, ejecting a portion of Earth into orbit. That rocky debris came together to form the moon.
will a neutron star collided with earth?
No
Explain the impact theory?
the impact theory states that the moon is formed billions of years ago from condensing gas and debris was thrown off when earth collided with a mars sized object
Is it true that the Moon was a chunk of Earth?
It is not true that the Moon was a chunk of Earth. The leading theory is that the Moon was formed from debris created when a Mars-sized object collided with Earth early in its history. This collision released material that eventually coalesced to form the Moon.
What theory states that the moon formed when a planet sized object collided with earth?
There are four main hypothesis for the formation of the moon. ; Fission hypothesis - The Moon broke off from the Earth ; Capture hypothesis - The Moon was captured ; Co-formation hypothesis - The Moon and Earth were created at the same time ; Giant Impact hypothesis - The Moon was created when a Mars sized object (Theia) crashed into the Earth.
