The Earth revolves around the Sun
The Earth Revolves Around the Sun
One year is the time required for the Earth to travel around the Sun.
For most of history, however, people did not know that the Earth moved around the Sun.
Instead, people believed that the Sun moved around the Earth.
The old idea that the Sun moved around the Earth is known as the geocentric theory.
This idea was first made famous by an ancient Greek scientist, Ptolemy,
who lived in Egypt nearly 2,000 years ago.
Some other Greek philosophers had suggested instead that the earth might travel around the sun.
However, this idea, which is known as the heliocentric theory, was not widely accepted.
For centuries, people in Europe did not seriously question Ptolemy's geocentric theory.
During the early 15th century, however, a Polish astronomer named Nicholas Copernicus
began to think that the heliocentric idea was right and that the geocentric idea was wrong.
Shortly before his death, Copernicus wrote a book that described the mathematical details
of his theory that the Earth revolved or traveled around the Sun.
Later, astronomers came to agree with Copernicus' view.
One of the most famous of these was Galileo, an Italian scientist.
Galileo is famous for demonstrating that light and heavy objects fall at exactly the same speed
unless an object is so light that it is slowed by the air.
Galileo was also the first astronomer to use a powerful telescope to observe the sky.
He discovered many unknown features of the moon, the sun, and the planets.
When Galileo announced that he believed in Copernicus' theory that the earth revolved
around the sun, some officials of the Roman Catholic Church were angry. They argued that
this theory was against the beliefs of the Church. Some Church officials disagreed with his view,
but the authorities decided that Galileo should be punished by house arrest. In other words,
Galileo was not allowed to leave his house.
Also, Galileo was forced to make a public statement
that renounced his belief in the heliocentric theory.
At about the same time that Galileo supported the heliocentric idea,
another astronomer did some important work that supported Copernicus' view.
This astronomer was Johannes Kepler, who lived in Germany.
Kepler used the observations of previous scientists
to figure out the motion of the planets around the sun.
He realized that the planets did not travel in circular paths,
but instead in paths that were elliptical or oval in shape.
Kepler's discoveries showed mathematically
how the planets would revolve around the sun.
Today, everyone knows that the earth moves around the sun,
but for a long time it seemed more reasonable to believe
that the sun moved around the earth.
We can thank the great scientists of the past who discovered the surprising truth.
