Saturn. It takes around 29.5 years to orbit our sun.
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
Pluto takes 248.09 Earth years to orbit the Sun once. However, please note that Pluto is no longer classified as a planet (like Earth, Mars, Jupiter etc.), it is now a 'dwarf planet'.
Yes. A year is how long it takes for Earth to orbit (go the whole way around) the sun. So if it's further out, then it takes longer to orbit, thus a longer year.
No planet orbits Earth.
Neptune takes longer to orbit the sun than Mars. Neptune's orbital period is about 165 Earth years, while Mars' orbital period is about 1.88 Earth years.
Venus has a rotation (spin) time of 243 Earth days, and a revolution (orbit) time of 224.7 Earth days, making it the planet with longer days than years.
Mars. The further out from the sun, the longer a planet takes to revolve round the sun. For example, Pluto's orbit takes over 200 (Earth) years.
A year for a planet is the time it takes for that planet to orbit the sun. Some planets take longer to orbit the sun because they are farther away from the sun than Earth, so those planets have a farther distance to cover to orbit the sun once than the Earth does.
Pluto
Neptune.
Jupiter has 4332 days in a year because its orbit around the Sun is much larger compared to Earth's orbit. Jupiter's greater distance from the Sun means it takes longer for the planet to complete one orbit, resulting in a longer year on Jupiter compared to Earth.
Well, basically different planets take longer to orbit the Sun. For example, Jupiter takes longer to orbit than earth, so Jupiter has a longer year. On Venus, a day lasts longer than a year as it takes longer to spin on its axis that to orbit the sun.
