Some 4.5 Billion years ago, a planet named "Thea" crashed into earth. This planet was about the size or Mars. Before Thea crashed into Earth, Earth was nothing more than a toxic wasteland.
No No No this did not happen this was just a myth on the news but for a matter if fact thy have found a skeleton of some sort that was 5 billion years old ans that's the answer if u dnt believe me then don't but that's a fact
Don't listen to the FTard in the paragraph above...it most certainly did happen; scientists have the evidence. There is no 5 billion year old skeleton, either.
If they do we have not found them.
We are called Earth. "Blue Planet" is a nickname for Earth, since our planet comprises primarily of water.
Mars is The Earth's brother planet
The planet that most resembles Earth in many factors is Mars. However, no planet most resembles the Earth in all factors.
planet earth is known for being the only planet to support life
No planet has crashed into earth, there was romers that, that was going to happen in 2012. but it didn't. the planet was called planet x or Nibiru
Scientists do not believe that any planet ever crashed into Venus.
Many times
There are theories that claim the Earth was formed by many disdinct, huge rocks or "planets' crashed into each other. The crashes' fragments bonded by gravity, thus making a survivable planet. It is also said that the moon was formed when a premature planet crashed into Earth. The debris joined together into a body, and thus, led to the moon.
They actually had a planet called Orpheus. I know that because we watched a video in my science class about it and how it crashed into Earth and became part of Earth.
billion years ago some planet at size of mars crash into earth then the dust and the rocks left over from the from the crashed planet crates the moon
If a dwarf star crashed into a planet,the planet would likely explode.
The biggest disaster that happened in history was when earth crashed with another planet millions of years ago. before any life existed on earth. the impact was so crustal that earth almost broke apart. but its rotation was 6 times faster than what it is now after the impact. and then a piece of the planet we crashed on was made in to what we know now, the moon! BTW this was written by a 11 year old. i saw it on discovery channel!
No, Earth is a planet orbiting the Sun.
Actually you are on the planet Poptropica, and to get into space you will need the crashed saucer Excalibur, in the mud field past the old mill.
The moon was born when earth smashed into another planet, but the leftover parts formed the moon when the two volcanic planets earth and the other crashed.
No. Mars has a similar rotational period but not revolution. For a planet to have the same revolution period as Earth would mean it would have to be in the same Orbit as Earth, with catastrophic results. One was in the same orbit as Earth during it's formation, it crashed into the Earth creating the Moon. It's possible that some extrasolar planet (that is, a planet of a star other than the Sun) might by coincidence have nearly the same rotational and/or revolution period, but we don't know of any yet (and it's not very likely that we ever will).
