Mars is the planet that takes about 6-9 months to travel to with current rocket technology. The closest planet to Earth, Venus, takes about 5-7 months to reach at its closest approach, but can be much longer depending on their orbital positions.
It takes Jupiter approximately 12 years to orbit the sun.
The planet you are referring to is the dwarf planet Pluto, which takes just over 248 years to orbit the Sun.
The planet Mars, which is the fourth planet from the sun, takes 1.88 Earth years to make one full orbit around the sun.

Neptune does and it takes 164.8 years to do so.
Neptune
The dwarf planet Pluto
That would be Saturn.
The planet that takes 248.5 Earth years to orbit the Sun is Neptune. It is the eighth planet in our solar system and has a very long orbital period due to its distance from the Sun.

This would depend on the planet, earth takes a year to go round the sun but that is because we named the time it takes for us to go round the sun a "year". The closer to the sun a planet is the less time it takes to circle it.
