Scientists think this probably happened and that the "planet" was about the size of Mars. However, it was several billions of years ago and the object that hit Earth is not usually given a name.
The moon that revolves around the earth is not a star, it is part of the earth that was thrown off into space when the earth was hit by a large asteroid early in its development, about 30 million years after the earth first was formed. The closest star to the Earth is our Sun, it is a star and it is called Sol.
The reason Pluto is not a planet is because it is very small, smaller than Earth's moon!
There is a theory that suggests a comet hit the earth and possible broke off a chunk creating the moon.
Yes scientist think that years ago ,before dinosouars were on earth,the planet hit the edge of earth and then started going around the earth as it got smaller
The name of the (proto)planet that hit (proto)Earth in the Giant Impactor hypothesis is Theia.
The moon's surface is covered in rocks because of the impacts of asteroids and cosmic debris over billions of years. These impacts have caused rocks from the moon's interior to be brought to the surface, creating a layer of moon rocks across its surface.
Yes, that is how Earth's formed, it hit a large protoplanet called Theia.
The moon is a satellite, although people propose now and then that the earth-moon system could be considered a double or binary planetary system. Since the barycenter (the center of gravity of the earth-moon) is within the body of the earth, considering the moon as a satellite makes more sense.
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.
An asteroid had hit Earth and knocked of a chunk that is now called the moon.
the Earth has a moon because while the earth was just a new planet, still forming, a big meteor hit earth and made a big dent somewhere... debris dust, and big chunks of earth flew into space. the pieces wandered around earth, the gravitational pull of earth kept it in an orbit. as the chunks and pieces flew around, they clumped together getting bigger and bigger. within weeks, our moon was formed. that's why the moon changes the tide level
if a meteor hit earth and a piece of earth (the moon) chipped off. earths gravitational pull could be sufficient to make the moon orbit around the earth.
