Mars, the smallest and closest planet to the Sun in the solar System, is getting smaller over time.
Astronomers have long recognized that the Union of Galaxy has been going through a shrinkage that has lasted for billions of years.
Although located near the Sun, the temperature inside Thuy has cooled, leading to contraction and creating many new features on the surface of this small planet.
One of the first evidences of Thuy's shrinkage was recorded in 1974, when the Mariner 10 explorer took the first images of cracks and cracks on Thuy's surface.
The Messenger space rover continued to explore the planet from 2011 to 2015, and discovered many new terrain features, highlighting the shrinkage taking place here.
The contraction of Thuy comes from the fact that the inside of the planet has gradually cooled, leading to a reduction in its mass.
This leads to damage to the surface structure, creating gaps and cracks, known as "push-ups". Similar to how an apple shrinks when it is dry, Sao Thuy shrinks due to the cooling inside it.
One of the most obvious signs of this contraction is the appearance of small cracks on the surface of Thuy.
This phenomenon often occurs when the planetary crust is stretched and bent. This contraction makes the surface tighter and cause cracks.
Although there is a lot of evidence that Thuy is shrinking, determining the extent and speed of the shrinkage is still a mystery.
Scientists are trying to measure the age of Thuy by measuring the density of craters on the surface. However, this method is complicated because the collision speed that creates volcanic canyons can be much larger.
The new study offers some interesting clues. Scientists have found that some cracks that appear to be moving on the surface of Thuy even though they have existed for billions of years.
These traces appear as cracks on the surface, showing that Thuy's contraction is still taking place and blurring geological characteristics.
This contraction is not only a narrowing of the mass of Thuy but also creates interesting changes on the surface of this planet. But there is still much to learn about this phenomenon, and more research will be needed to answer the questions still being raised about Thuy and its contraction.
