The Earth’s rotation is gradually slowing
Due to a transfer of Earth's rotational momentum to the Moon's orbital momentum as tidal friction slows the Earth's rotation..
It is well known that for four and one half billion years, its entire lifetime, the Earth's rotation has been gradually slowing.The slowing rotation of the Earth results in a longer day as well as a longer month. Once the length of a day equals the length of a month, the tidal friction mechanism will cease.That's been projected to happen once the day and month both equal about 47 (current) days, billions of years in the future.
The Earth was once believed to be the centre of the universe
It is known as the Fixed Earth Theory or geocentric it model states that the Earth is, despite all evidence to the contrary, located at the very center of the universe, and the rest of the cosmos revolve around our very own planet. some people have still refused to let go of the idea that anything but humans could be at the center of the universe. It was most notably argued by Ptolemy.
Earth is the only planet not named after a god The Name
Earth is the only one in our solar system that does not come from Greco-Roman mythology. All of the other planets were named after Greek and Roman gods and goddesses. The word ‘Earth’ came from the Anglo-Saxon word ‘erda’ and it’s germanic equivalent ‘erde’ which means ground or soil. In Old English, the word became ‘eor(th)e’ or ‘ertha ‘.
The Earth is the most dense planet
Of all the planets in our solar system, the Earth has the greatest density. The density of the Earth is 5.513 g/cm3(around 12 grams per cubic centimeter). This is an average of all of the material on the planet. Water is of course, much less dense than iron, hence an average is needed for ease of use.Meanwhile Mercury comes second in the race of the most dense planet with 5.43 g/cm³. Close Enough!
Earth doesn't take whole 24hours to rotate around its axis
Yes. You read it right. Earth takes 23 hours, 56 minutes and 4 seconds to rotate on its axis and not 24 hours and there are 365 and a quarter day in a year (The extra quarter day is why we need a leap year every four years.)
Earth has more than one Moon
You’re aware that The Earth has 1 moon. But did you know there are 2 additional asteroids locked into a co-orbital orbits with Earth? They’re called 3753 Cruithne and 2002 AA29.
The 3753 Cruithne was Discovered by Duncan Waldron on October 10, 1986.Its approximately 5kilometres in diameter and its distance from earth is 12 million kilometres. Cruithne is in a normal elliptic orbit around the Sun. Its period of revolution around the Sun, approximately 364 days at present, is almost equal to that of the Earth. Because of this, Cruithne and Earth appear to "follow" each other in their paths around the Sun.
The 2002 AA29 was Discovered by LINEAR(Lincoln Near Earth Asteroid Research) on January 9, 2002. Its only about 20–100 metres in diameter and its distance from earth is 5.8 million kilometres. It has almost circular orbit very similar to that of the Earth around sun
The Earth is not actually round in shape.
Planet Earth is not, in fact, perfectly round it is geoid.. The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Isaac Newton first proposed that Earth was not perfectly round. Instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator. He was correct!
Each winter there are about 1 septillion snow crystals that drop from the sky.
Snow is precipitation in the form of flakes of crystalline water ice that falls from clouds. Snow crystals form when tiny supercooled cloud droplets (about 10 μm in diameter) freeze. And each winter there are about 1 septillion (1, 000, 000, 000, 000, 000, 000, 000, 000 or a trillion trillion) snow crystals that drop from the sky
1.3 million Earths could fit inside the sun, an average-sized star.
Sun has a diameter of 1.392 million km and earth’s diameter is hardly 12,742 kmThe ratio of the Sun's radius to the Earth's radius is
1,392,000/12756 = 109.1
This means the ratio of their volumes is 109.1 x 109.1 x 109.1, which is about 1,300,000,and that means that 1,300,000 Earths should fit inside the Sun.
There are more living organisms in a teaspoonful of soil than there are people on earth
The soil is actually an ecosystem in which millions of living creatures lives. There can be more creatures in a teaspoonful of soil than there are people in the entire planet earth, i.e. more than 7+ billion. The soil is the source of many different types of food for these creatures and is also the source of their nutrition and water.
