The Earth is the only planet in the Solar System where Life exists. We live on Earth, but there are a lot of facts we don't know about the Earth, Today in this Blog you will be aware of some of them so keep reading and enjoy the Facts.

1. Age of the Earth:
Yes yes, you read it right the Age of the Earth did you ever think what is the age of the earth.
The age of the Earth is 4.543 Billion years, according to the scientists the Earth was created or made 4.543 Billion years ago means 454 Crore years ago. Now you have this question coming to your mind that how did scientists calculate the age of the earth so for your information, I want to tell you that the scientists had calculated the age of the Earth by Radiometric Dating. This is the technique via scientists calculates the age of the rock or any other kind of material so the oldest rock on earth is 4.543 Billion years old.

2. The temperature of the Earth:
The average temperature of the Earth is 16°C but on the Earth, there are a lot of places where the normal temperature differs. But on 10 July 1913 Deathvalley, United States, the highest temperature was recorded that was 56.7°C, and the lowest temperature on Earth was -89.2°C that was recorded on 21 July 1983 Vostok Station, Russia.

3. The Earth was once believed to be the center of the universe:
In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth.[1] The geocentric model was the predominant description of the cosmos in many ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt.

Two observations supported the idea that Earth was the center of the Universe:

First, from anywhere on Earth, the Sun appears to revolve around Earth once per day. While the Moon and the planets have their own motions, they also appear to revolve around Earth about once per day. The stars appeared to be fixed on a celestial sphere rotating once each day about an axis through the geographic poles of Earth.[2]
Second, Earth seems to be unmoving from the perspective of an earthbound observer; it feels solid, stable, and stationary.



Ancient Greek, ancient Roman, and medieval philosophers usually combined the geocentric model with a spherical Earth, in contrast to the older flat-Earth model implied in some mythology.[n 1][n 2][5] The ancient Jewish Babylonian uranography pictured a flat Earth with a dome-shaped, rigid canopy called the firmament placed over it (רקיע- rāqîa').[n 3][n 4][n 5][n 6][n 7][n 8] However, the Greek astronomer and mathematician Aristarchus of Samos (c. 310 – c. 230 BC) developed a heliocentric model placing all of the then-known planets in their correct order around the Sun.[12] The ancient Greeks believed that the motions of the planets were circular and not elliptical, a view that was not challenged in Western culture until the 17th century, when Johannes Kepler postulated that orbits were heliocentric and elliptical (Kepler's first law of planetary motion). In 1687 Newton showed that elliptical orbits could be derived from his laws of gravitation.

The astronomical predictions of Ptolemy's geocentric model, developed in the 2nd century CE, served as the basis for preparing astrological and astronomical charts for over 1500 years. The geocentric model held sway into the early modern age, but from the late 16th century onward, it was gradually superseded by the heliocentric model of Copernicus (1473-1543), Galileo (1564-1642), and Kepler (1571-1630). There was much resistance to the transition between these two theories. Some Christian theologians were reluctant to reject a traditional theory[citation needed] that agreed with Biblical passages.[13] Others felt that a new, unknown theory could not subvert an accepted consensus for geocentrism.

4. The rotation of the Earth is gradually slowing down:
Yes yes, you again read it right the rotation speed of Earth is slowing down.
Earth's rotation is slowing down at 17 milliseconds per hundred years, but why the earth's rotation speed is slowing down. The Moon is going far from Earth at 3.78 centimeters per year that is why the rotation speed of Earth slowing down.

5. Revolution speed of the Earth:
We all know that the Earth is revolving around the sun, but did you know what is the revolution speed of the Earth. Earth's revolution speed is 30 KM per second. The amazing thing is this that the Earth is not traveling alone rather it is traveling with you it means you're traveling 30 KM per second but you cant fell it.
