That follows from Keppler's Laws of Planetary motion.
Mercury is the fastest moving planet around the sun. It is second slowest to rotate about its axis, Venus being the slowest.

Neptune is the slowest and mercury is the fastest
Mercury has the slowest revolution around the sun, taking about 88 Earth days to complete one orbit.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.

The order of the planets' rotation speeds from fastest to slowest is Jupiter, Saturn, Mars, Earth, Venus, Uranus, Neptune, and Mercury. This ranking is based on the time it takes for each planet to complete one rotation on its axis.
snails are the slowest mollusk. But that has nothing to do with what the slowest insect is. The wheel bug is probably the slowest insect.
The superlative of slow is slowest. The comparative is slower.
Mercury has the slowest orbital velocity of all the planets relative to the Sun due to its proximity to the Sun and its relatively small mass. While it orbits the Sun at an average distance of about 57.91 million kilometers, its high density and gravitational pull result in a slower velocity compared to planets further out. Additionally, the effects of solar gravity on Mercury lead to a more pronounced elliptical orbit, which can influence its velocity at different points in its orbit. As a result, Mercury's average orbital speed is lower than that of the other planets.
Orbital speed is determined by the mass of the body and the distance from the sun. Given its extreme distance, Pluto has the slowest orbit. However, Pluto is no longer considered a planet, but instead a planetoid. Therefore Neptune now has the slowest orbit.
Sloths are the slowest mammals.
