INTRODUCTION

All through human historical past we now have sought to understand our dwelling planet. Nonetheless, the training curve has been steep, with many errors having been made alongside the best way. For instance, it was not till the time of the traditional Romans that the world was understood to be spherical relatively than flat. A second instance is the idea that the Sun revolved across the Earth. Solely within the sixteenth-century, by means of the work of Copernicus, did we settle for that, actually, the Earth was merely a planet orbiting the Sun.

Maybe most significantly, it's over the past two centuries that science has allowed us to see that the Earth is each an atypical and distinctive place in the Solar System. On one hand, lots of its characterisitcs are relatively unexceptional. Take, for instance, its measurement, inside, and geological processes— the fifth largest out of the eight planets, it's near the median by way of measurement; its inside construction is sort of similar to the three different terrestrial planets; and the identical geological processes that form its floor may be discovered not solely on different planets, but in addition on planetary moons. Nonetheless, the Earth is special in a particular regard— all of the solar system, the Earth is the only world known to foster life.

Individuals are proper to be fascinated by the Earth – it’s our dwelling and makes human existence potential! For that reason scientists dedicate loads time and vitality on exposing the wonders of Earth.  Right here’s a handful of fascinating data about Earth that’ve been discovered…

Eye-opening Earth data

• The Earth isn’t the perfect sphere you might assume it is. Our planet actually bulges on the equator whereas flattening on the poles.
• Most people know that Earth is rotating on its axis and assume that it takes 24 hours for the earth to complete its rotation. However it  actually takes 4 minutes less (23hrs, 56minutes, 4sec).
• If that wasn’t ample, the planet moreover takes 365.2564 days to rotate throughout the sun. That additional quarter adds up and eventually results in a leap year.
• The planet simply is not still .It is actually moving through space at 107,000 km per hour.But you can’t feel that motion on Earth.
• The Earth’s rotation is slowing. That's going down at a cost of 17 milliseconds every few centuries. So the deceleration is imperceptible.
• As compared with its measurement, the Earth has an important natural satellite (the Moon) inside the Milky Way.
• People thought that the Earth was the centre of the universe. This notion was informed by the easiest way, the heavenly  bodies appeared to move as seen from the Earth’s ground.
