Mercury…is on the fast track!
Mercury is the smallest and also the fastest planet in the Solar System.
I am the closest planet to the Sun and named after the messenger to the Roman Gods, whose speed was enhanced by his winged sandals. I am the fastest planet in the Solar System, flying around the Sun in a mere 88 days. I race through space at 30 miles per second, outpacing the Earth, who clocks in at 19 miles a second. Although I am the smallest planet in the Solar System, my large iron core makes me the second heaviest, only slightly lighter than Earth. My appearance is similar to the Earth’s Moon, for I am heavily cratered, lack an atmosphere and have no natural satellites.
