It’s a simple but effective way to represent the smallest planet in our solar system. Mercury is the closest planet to the Sun, which means it experiences extreme temperatures. Despite its proximity to the Sun, Mercury has virtually no atmosphere to trap heat, resulting in freezing temperatures at night and scorching heat during the day.

The planet is also known for its heavily cratered surface, similar to our Moon, caused by billions of years of asteroid impacts. One of the fascinating things about Mercury is its slow rotation—it takes about 59 Earth days to complete a single rotation. However, it moves quickly around the Sun, completing an orbit in just 88 Earth days, which makes its years much shorter than ours.
