Mercury takes 87.969 days to orbit the sun.
It is approx 88 days.
Mercury because it is the planet closest to the sun.
After Mercury, the planet that takes the least amount of time to orbit the sun is Venus, which orbits the sun in about 225 Earth days.
Mercury, the closest planet to the Sun, completes an orbit in just 88 Earth days.
Mercury is the closest planet to the sun and it is the fastest to orbit the sun. It takes 88 days for the Mercury to completely orbit the sun.
The question needs to be more specific. It it the time to travel to Mercury, the time that Mercury takes to orbit around the sun?
Mercury takes the most least time to orbit the sun. It takes 88 days.

The two reasons why Mars takes longer to orbit the Sun than Mercury are its greater distance from the Sun and its slower orbital speed due to its larger orbit. Mercury is much closer to the Sun and has a shorter orbit around it compared to Mars.
The orbits of planets have a point called the "perihelion", which is the point where the planet is closest to the sun. Over time, the perihelion of Mercury's orbit changes position, orbit around the sun itself. General relatively correctly predicted that the shift in the perihelion of Mercury's orbit is much faster than is predicted using Newton's laws.
