Mercury has gradually been shrinking
March 18 , 2014
The smallest planet in our solar system has been getting more small but the good news is that Mercury is less likely to disappear completely.
Reports suggest that it took the planet 4 billion years to lose about 8.6 miles of diameter and recent images have let scientists to map as to how much its surface has changed. "We have the big picture now," the study's lead author said.
Another scientist mentioned that the landscape is crumpling up and "massive slabs of rock are sliding over one another."
This new finding will allow experts to investigate other questions related to the shrinking.
