The moon is Earth's only natural satellite, and is the fifth largest moon in the solar system.
And the Moon is the brightest celestial body after the Sun. Even though the Moon looks very white and bright, the Moon's surface is actually dark with a brightness slightly higher than liquid asphalt.
But what happens if the moon shrinks and shrinks, it is as revealed by NASA space station recently. The following explanation ...

NASA station's LRO (Lunar Reconnaissance Orbiter), issued the latest imaging analysis of the moon.
NASA said, if the moon experiences shrinkage that makes the lunar surface wrinkle, it is due to earthquake shocks. The analysis was based on a survey of more than 12,000 images.
All the images show that the moon basin of Mare Frigoris near the north pole of the Moon was cracked, and shifted. The lunar basin Mare Frigoris is one of many broad basins which are assumed to have died from a geological point of view.
Unlike the Earth, the Moon does not have a tectonic plate. On the contrary, tectonic activity on the moon occurs because slowly the Earth satellite is losing heat, since it was formed 4.5 billion years ago. The intended thing in turn makes the lunar surface wrinkled, like wine that shrinks into raisins.
AFP, Tuesday (05/14/2019) published, that the moon has a fragile crust. When an earthquake occurs and the inside shrinks, the surface breaks easily and produces what is called a thrust fault, where one part of the crust is pushed up to the adjacent part.
And that ultimately made the moon "shrink" by about 50 meters over the past several hundred million years. Apollo astronauts first began measuring seismic activity on the Moon in the 1960 and 1970 years.
They found seismic activity mostly occurred in the abdomen of the moon, and only a small amount occurred on its surface.
According to an analysis published in Nature Geoscience, experts examined shallow moon earthquakes recorded during the Apollo mission and then linked them to the surface features of the new moon.
"Chances are, earthquakes still occur todaymaybe all this time we've only seen tectonic earthquakes shake the Earth, so knowing that the Moon was also rocked by an earthquake I think is very interesting". Said the assistant professor of geology at the University of Maryland, Nicholas Schmerr
Related to shrinking and shrinking the moon as revealed by NASA, is it possible that it will have a negative impact on the earth, or is it possible that it also has an impact on human health or all living things on earth ...?. To answer this question, please write it in the comments column below...
