Being the planet closest to the Sun, Mercury is the planet that travels fastest in its orbit,
and the planet that completes an orbital revolution in the shortest time. Mercury circles the
sun in only 88 earth days.
That really depends on what is traveling and at what speed.
Mercury has no twin planet, it is not really like any of the other planets.
Both the planet and the gas were named for the Roman god Mercury who was known for his speed and mobility. The planet was named for this because of its fast orbit.

Both the planet Mercury and the chemical mercury - also written as Hg - are named after the Roman god Mercury (latin: Mercurius), known for speed and mobility. The chemical is only named after the god. Humans mine mercury ore on Earth, not from the planet Mercury.

Not really. If Mercury suddenly disappeared, it would not significantly affect the rest of the Solar System.
