OUR PLANET:THE EARTH
The Earth emerged from a swirling Nebulae of Interstellar gas and also dust along with the sun and and other bodies in our solar system. Countless mineral grains and other particles collided with each other under the force of inherent gravity and condensed into largest planet which we all know today is our planet The Earth 🌎.

The Earth is the third planet from the sun and the only known planet to have a living environment and supports all life forms. The earth looks like a spheroid but it is flatter at its poles, with an equatorial diameter of 12,756 km and a polar diameter of 12,714 km. It rotates once on its own axis in 23 hours 55 minutes and 56 seconds and tilted at an angle of 23.5 degrees, and orbit around the sun in an ellipse in 365 days, 6 hours and 8 minutes.
