science cannot really express the earth as a percentage because the universe is ever expanding, while the earth is constant. Even as you finish reading this sentence, the universe has grown bigger than what it was when you started reading

I very much regret that the exact percentage is not known since no one has managed to find a way to find the exact mass of the earth's crust, which would probably form the denominator of such a percentage.
pi is a universal constant. It is a transcendental number which is a special kind of irrational number. It cannot be expressed as a terminating or repeating decimal, nor as a ratio of integers or surds. There are various ways in which pi can be calculated and expressed. Commonly used approximations are 22/7, 3.14, 3.14159. Last year pi was calculated to 5 trillion digits although 40 digits are thought to be sufficient to calculate the angle subtended on earth by a hydrogen atom at the far end of the known universe!
A number that cannot be expressed as the ratio of two integers is known as an irrational number.
One of the largest is called Graham's Number, which has so many digits that it can only be expressed as "powers of powers of powers". The last ten digits of Graham's number are ...2464195387. But the observable universe is too small to contain a written representation of the whole number, even if the digits were of subatomic size. It is many orders of magnitude greater than the number of elementary particles in the known universe.
That is un known.

Aristarchus of Samoa showed the first known model that placed the Sun at the centre of the known Universe.
earth
The very center. he belived everything revolved around the earth.
The critical realization that Earth is not at the center of the universe is now known as the Copernican Revolution. The idea that neither Earth nor Sun occupy a special place in the universe is known as the "Copernican Principle". This hypothesis is scientifically classified as a "Principle of Mediocrity".
The Earth-centered model of the universe
It contains the only known life in the universe.
There exists only one known universe and the Earth is in it. Even if the theory of multiple dimensions was proven, the Earth would actually still exist in all of those separate dimensions at once.
He presented the first known model that placed the sun at the center of the known universe with the earth revolving around it. This was in the 3rd century.
It is the only place in the known universe that has been verified to contain intelligent life.

Earth is the name we have given to our planet. [It may not be its real name, and may be known as something else. To paraphrase Lewis Carroll]
