67 Interesting Facts About Earth – Our Mother Planet

Last updated on November 26th, 2017

The Earth is a beautiful place to live and explore. It has a plenty of life supporting features and is constantly changing/evolving. Several scientists and geologist have explored Earth and other planets. Here we have compiled a list of some interesting facts about Earth that will help you learn more about our mother planet. Let’s get started!

About Earth’s formation, location, speed, composition, existence of life

#1. Earth is the third planet from the Sun and is the largest of the four terrestrial planets namely Mercury, Venus, Earth, and Mars. These planets are also closest to the Sun.

#2. The existence of water in the liquid phase on Earth is due to the temperature span that exists on the Earth: 0 – 100 degree Celsius. Water boils at 100 degree Celsius, thus converting it into gas and making it unusable for consumption by living beings including humans, animals, and birds etc…

#3. Earth is also the only place in the solar system where water can be present in all the three states – solid, liquid and gas.

#4. We are all traveling around the Sun at an average velocity of 107,182 kilometers per hour. And at the same time, we are also spinning with an enormous speed – that could be 1000 miles per hour depending on your position on Earth.

#5. Earth receives between 100 and 300 metric ton of cosmic dust (the dust which exists in outer space, as well as all over planet Earth) every day (data collected from satellite observations.) However, some other estimates suggest that the incoming dust could be as low as 5 metric ton per day.

#6. Despite the fact that the earth is made up of more than 70% of water, do not be surprised to learn that water accounts for less than 1% of Earth’s mass.

#7. In size, Earth is slightly larger than Venus.

#8. Earth formed some 4.54 billion years ago.

#9. The force of gravity in the Hudson Bay region of Canada is less than that on the rest of the planet. There are various theories that scientists associate with this effect but no one is sure as to why this is the case.

#10. It is estimated that life came to existence on Earth some 4.1 billion years ago.

#11. It is also interesting to note that more than 95% of Earth’s ocean are still unexplored.

Facts about Earth and the Moon

#12. Tides in oceans on Earth happen due to the force of gravitation between the Earth and the moon. Moon pulls up water in oceans and even in lakes, due to its gravitational force.

#13. Earth has just one moon whereas Jupiter has 67 moons.

#14. The moon (radius – 1,738 kilometer) is the fifth largest moon in the Solar System after Ganymede (orbits: Jupiter), Titan (orbits: Saturn), Callisto (orbits: Jupiter), and Io (orbits: Jupiter).

#15. The Moon reflects Sun’s light on the Earth when the Sun is on the other side of the Earth meaning when there is the night on one side of the planet.

#16. The same side of the moon is always facing the Earth, meaning the moon is in synchronous rotation with the Earth.

#17. Moon is Earth’s only permanent natural satellite. (FYI – there are 181 known natural moons that are orbiting the full-size and dwarf planets in our solar system)

#18. Moon, earth’s natural satellite, is thought to have been formed from Earth after the impact of a Mars-sized object, named Theia.
