It’s amazing that people now know more about space than the facts about the Earth we live on.
For example, we call Earth the blue planet, even though scientists believe it is not always green, or that the moon is not the only satellite of the Earth.
Here are strange facts about our Earth.
1. Mysterious Gold Warehouse

According to experts, about 80% of the gold on Earth has yet to be found and they may be located very deep underground.
It is estimated that if all the gold in the world were found, it could cover the entire land surface of the Earth with a depth of about 50cm.
2. The Moon may have once been part of the Earth

Scientists think that our Moon appeared due to the collision of the Earth colliding with another large object. Accordingly, the collision led to the formation of the Moon and then this planet became a satellite of the Earth.
3. Earth’s magnetic field is changing

The Magnetic Field is the Earth’s protective shield that protects the planet from the solar wind and cosmic radiation, but in fact it is constantly changing. According to scientific research, the magnetic field has moved about 965km since the 19th century.
Going out from the southern hemisphere and into the northern hemisphere, after a while, the speed of the magnetic field will peak and then slow down. The Earth’s magnetic field is weakening at such a rapid rate that the magnetic poles are in danger of reversing, scientists say.
4. Earth can “survive” a second Moon

Some scientists believe that our Earth has a second satellite. According to research, in addition to the Moon, there is another object in the universe that revolves around the Earth. However, this may just be a temporary satellite.
It is believed that the Earth’s gravity sometimes attracts quite large asteroids, and they are attracted to our planet for a period of time (about 3 revolutions) before wandering through space great.
5. Earthquakes on the Moon

This phenomenon is also known as moon motion. Perhaps many people think that the moon cave is just a scientific fantasy.
However, in reality, although they do not occur as often as on Earth, earthquakes occur deeper and closer to the core of the Moon. Scientists believe this is due to the gravitational pull of the Sun and Earth.
6. Earth used to be purple

A scientist at the University of Maryland (USA) believes that, 4 billion years ago, the primitive Earth used to be purple. This is because in ancient times, plants may have used molecules instead of chlorophyll (chlorophyll) to absorb sunlight.
These molecules were able to make ancient plants purple, so that the Earth at that time could have taken this color.
7. Scientists find “twin” planet with Earth

HD 904790 b is the name of a planet that could be inhabited in the future. This planet is located in the Milky Way, and possesses some of the same outstanding features as Earth, such as having a special atmosphere, climate, natural resources and even fresh water.
According to astronomers’ calculations, it will take humans about 300,000 years to set foot on this planet.
8. Different gravity

Since the Earth is not a perfect sphere, the mass of this blue planet is not uniform. The difference in mass causes fluctuations in gravity in different places on Earth.
One of the examples of this anomalous feature is Hudson Bay (Canada), which has a much lower gravity than other areas.
