In Greek mythology Theia was a titan
And the mother of the Goddess of the moon
And in astronomy Theia was a planet
That is said to have collided with the Earth
Long ago
According to the giant impact hypothesis Theia orbited the Sun
Nearly along the orbit of the Proto-Earth
Where it would tend to remain
But by the gravitational influence of Jupiter and Venus
From that relationship it was perturbed away
It was traveling no faster than 9 thousand miles an hour
When it collided with our planet on its way
Theia, Mother of the Moon, colliding with the earth
Billion years ago
Theia Theia
Theia may have formed in the outer solar system
About the size of Mars
It is suggested that much water of the Earth
Could have originated there
Theia would have grown potentially until it left its course
4.5 billion years in our past
When it collided with the Earth many pieces were ejected
And those pieces merged to form the moon to last
Theia, Mother of the Moon, colliding with the earth
Billion years ago
Theia Theia
The lunar rock samples, retrieved by Apollo astronauts
Were found to be similar in composition to the Earth's crust
And so they were likely
Removed from Earth in some violent event
Theia, Mother of the Moon, colliding with the earth
Billion years ago
Theia, creating fall and spring by causing axial tilt
Billion years ago
