Mercury is getting smaller

The size of Glass, the smallest planet in the solar system, is getting smaller and smaller.

That is the conclusion of the Washington Carnegie Institute (USA) after analyzing the data collected by the Messenger spacecraft when flying near Glass with a distance of 200 km earlier in the year.

Scientists believe that the shrinkage is due to the effect of the Glass core cooling down and the contraction rate being faster than astronomers by one-thirds.

Besides, after 6 months of analyzing images transmitted from Messenger, experts discovered that despite the intense heat of the scorching sun, Glass still had water in some forms.

In addition, it has volcanoes and images that provide evidence that the planet has been very active in the early period.
