The Distance of the Earth and the Moon Farther Each Year, Is That a Sign of the Moon Will Disappear?
Friends must know that Earth has a natural satellite that we know as the Moon.
Just like other celestial bodies, Earth and Moon also have a distance that separates the two celestial bodies.
Earth and other planets have orbits that are pathways for their rotation and revolution in the order of the solar system.
However, shocking news comes from observations that show that the Earth and the Moon are getting farther away each year.
According to Cornell University, every year the distance of the Earth and the Moon increases by 3.8 centimeters.
Indeed, this change in distance is very small, but many think this is a sign that the Moon will disappear and leave Earth.
Actually, why is the distance of the Earth and the Moon getting farther away every year? We refer to the following explanation, let's!
The first time it was known the distance between the Earth and the Moon increased each year was when Neil Armstrong and the team left a reflector when landing on the Moon in 1969.
The reflector is useful for observing the movement of the Moon.
Then a Professor from the University of Maryland named Carrol Alley shot a laser from the observatory to the reflector on the Moon.
A surprising thing revealed that the distance of the Earth and the Moon continues to increase every year.
This finding is reinforced by other findings from an observatory in Texas that reveal there is an increase in the distance of 3.8 centimeters every year in the Moon's orbit.
How did it happen?
The moon produces two forces, the centrifugal force and the centripetal force around the Earth.
Centrifugal force is a force that is formed when objects move in a circle and this force always away from the center of the object's circular motion itself.
Whereas this centripetal force is the opposite. The force always goes to the center of the object's circular motion.
The farther the distance of the object to the center of motion, the stronger the centrifugal force.
The center of the Earth is the center of the Moon's circular motion. The closer to the center of the Earth, the greater the centripetal force.
When the Moon moves, the gravity of the Earth will pull the Moon so that a circular motion appears.
Unfortunately the centrifugal and centripetal forces of the Moon are not balanced and cause the Moon to move faster than it should be.
Because of that the Moon cannot keep its circular motion around the Earth.
This is also caused by the centrifugal force of the Moon which is greater than the centripetal force which causes it to move further away.
However, this will not make the Moon disappear from Earth.
Reporting from infoastronomy.org, Space said 50 billion more know the motion of the Moon will be more stable and stop moving away.
When it reaches that phase, the Moon which originally only needed 27 days to circle the Earth will change to 47 days.
