Look for the one that is furthest away. The revolution period goes up with the size of the orbit to the 3/2 power, e.g. a planet at 4 AU distance from the Sun would take 8 years to go round because 8 = 4^(1.5)
Saturn has an orbital radius of just under 10 AU and takes about 30 years to go round.
Saturn
Out of Mercury, Earth, Mars, and Jupiter, Jupiter has the longest year.
Mercury is the shortest and Neptune is the longest

If you mean revolution on it axis (spin/day length) rather than orbital period, then the answer is the planet Mercury, where time between sunrises is roughly 176 Earth days.
Jupiter takes 10 hours to complete one rotation.
The order of the planets by longest year is the normal order (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The farther away a planet's orbit is from the Sun, the longer the year.
Mercury has the slowest revolution around the sun, taking about 88 Earth days to complete one orbit.
um well who knows
The naked eye visible planets. Mercury, Venus, Earth, Mars, Jupiter and Saturn.
Mercury has the longest year in revolution among the inner planets, taking about 88 Earth days to complete one orbit around the Sun.
No. The main belt is between Mars and Jupiter.
