The planet Theia is a planet that was theorized to explain the formation of the Moon. The theory is that Theia was formed along with Earth at one of the Lagrangian points and then became unstable when its mass reached about 10% of Earth's mass and was attracted to and collided with Earth, thus forming the Moon.

How big was the planet theia?
Theia is believed to have been about the size of Mars, or about 6,800 kilometers across.
When did earth and theia collide?
There is a theory that Theia (Thea) was an additional planet that formed in a similar orbit to earth, and that Earth and Theia collided approximately 4.533 billion years ago (4,533,000,000 years ago). The belief is that the resulting collision caused debris from earth to be blasted into orbit causing the formation of the moon.A good summary is found here:http://www.dailygalaxy.com/my_weblog/2007/07/the-theia-hypot.html
How many years ago did the world explode?
The Earth did not explode but it had a fairly heavy collision with a planet called Theia about 4.6 billion years ago.
What was the name of the planet that collied with earth that ultimately crated the Moon?
Bearing in mind that this is a theory, that there is no certain proof that a planet the size of Mars or so collided with the infant Earth to create the Moon, the proposed name for this hypothetical planet is Theia.Based on very limited information - moon rocks collected by six Apollo missions, and not much else - the currently accepted theory of the origin of the Moon is that a planet (perhaps the size of Mars) which had perhaps formed near the Earth or at least near its orbit, finally collided with it. The impact reshaped the Earth, may have caused its spin, and possibly caused Earth's 23.5 degree axial tilt. The planet, named "Theia", may have merged with the Earth (or parts may have ricocheted away) and substantial portions of the Earth's crust were blasted back into space. Over millions of years, the debris and rocks left over from the remains of Theia and the matter blasted away from Earth into space coalesced to form the Moon.Did this really happen? Good question! The math seems to work out, and the lunar samples seem to indicate that moon rocks were at one time Earth rocks; or at least, they came from the same source. Of course, it was about 4 BILLION years ago, and both the Earth and the Moon have been steadily bombarded by other meteors all the years since.
What bodies in the solar system collided and combined to form earth?

How big was the planet theia?
Theia is believed to have been about the size of Mars, or about 6,800 kilometers across.
What was the name of the planet that hit earth?
The name of the (proto)planet that hit (proto)Earth in the Giant Impactor hypothesis is Theia.
Can a planet get a large moon from an enormous collision?
Yes, that is how Earth's formed, it hit a large protoplanet called Theia.

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.
Where did Earth's moon come from?
It is believed to have formed around 4.5 billion years ago, following a collision between Earth and another planet (tentatively called Theia). This is thought to have thrown around half of Theia's mass into orbit around the Earth, which then coalesced into the Moon.
How many years ago did the world explode?
The Earth did not explode but it had a fairly heavy collision with a planet called Theia about 4.6 billion years ago.
What is the latin name for the greek goddess Theia?
Theia had no Roman/Latin equivalent.
What is the duration of I theia ap' to Chicago?
The duration of I theia ap' to Chicago is 1.2 hours.
When was I theia ap' to Chicago created?
I theia ap' to Chicago was created on 1957-12-16.
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.
Is the planet Thea still there?
Theia is a hypothetical planet, used to explain the creation of the Moon. If it ever existed, it is unknown whether it still exists. For example, it may have merged with other pieces, to form one of the other planets.
