A new study has revealed that Mercury contracted up to 30% more than previously estimated estimates since its formation. The planet is naturally contracting as its interior loses heat over the years. Currently, the diameter of Mercury was reduced by about 23 kilometers, ...

Mercury Is Slowly Collapsing in on Itself, and It's Worse Than We Thought
Mercury is our solar system’s smallest planet, and it is determined to get smaller. It’s already about one-third the width of the Earth, and, according to a new study published in Geophysical Research Letters, it’s shriveling at a pace of 10 to 30 percent faster than anyone had previously realized. When Mercury formed 4.5 billion […]
A study has revealed that Mercury, the smallest planet in the solar system, has shrunk much more than previously known. The study suggests that the extent of Mercury's reduction has been underestimated because traces of tectonic activity on its surface have been found to be fewer than actually exist. Currently, Mercury's average diameter is 4,880 km, which is comparable to Earth's
New estimates based on measurements of the surface ripples of the planet show that Mercury is contracting up to 30% faster than expected: this is what is happening
