The term year refers to the amount of time it takes a planet to complete a full orbit around a star. The units of time for planetary orbits are specified relative to Earth time, typically Earth days or Earth years.
The wider an orbit is of a planet, the less is the gravitational force exerted on it by a star, and thus the planet travels slower. This is affected further by the size of the planet: larger planets have greater attraction to the sun, since the gravitational force between two objects requires the masses of both objects, so they would have to travel faster to escape the gravity of their parent star(s). This is complicated further by the gravitational influences of other solar objects.
Logic aside, however, the comparison of the orbital years of planets is easily confirmed through observation. In the related NASA link below, the table shows that each planet in our solar system has a longer year the further from the sun it is. Hence, Jupiter has a longer year than Earth, Saturn has a longer year than Jupiter, and so forth.
Also, for sake of precision, keep in mind that terrestrial refers to Earth, while jovian refers to Jupiter (jovial means having good humor).
What else can I help you with?
Do Jovian planets rotate faster than Terrestrial planets?
Yes, Jovian planets rotate faster than terrestrial planets. For example, Jupiter completes a rotation in about 10 hours, while Earth takes roughly 24 hours. This difference is mainly due to the Jovian planets having a greater amount of mass and their composition, which affects their rotation speeds.
How do the terrestrial planets differ from the Jovian planets?
The jovian planets have no solid ground just compressed gases the terrestrial planets have solid ground. The Jovian planets are named gas giants because they are farther then the sun and are not solid and the terrestrial planets are closer to the sun and do not have as much gases.
Which terrestrial planet has the oldest surface?
Mercury is believed to have the oldest surface among terrestrial planets in our solar system. Its surface is heavily cratered, indicating that it has not undergone significant geological changes for billions of years.
Which planets have a year longer than the Earth?
All the planets further away from the sun than Earth is
Which planets have years longer than one earth year?
Jupiter, Saturn, Uranus, and Neptune have years longer than one Earth year. Jupiter's year is about 12 Earth years, Saturn's is about 29 Earth years, Uranus's is about 84 Earth years, and Neptune's is about 165 Earth years.
Do Jovian planets rotate faster than Terrestrial planets?
Yes, Jovian planets rotate faster than terrestrial planets. For example, Jupiter completes a rotation in about 10 hours, while Earth takes roughly 24 hours. This difference is mainly due to the Jovian planets having a greater amount of mass and their composition, which affects their rotation speeds.

Why do the further planets have longer years and lower temperatures?
The further planets have longer years because their orbits are farther away from the sun, so it takes them longer to complete one orbit. The lower temperatures are a result of receiving less heat and light from the sun due to their distance, making them colder compared to the planets closer to the sun.
Which planets have a year longer than the Earth?
All the planets further away from the sun than Earth is
Why does it takes some planets only days to revolve around the sun and other planets more than one hundred years?
It takes longer because the planets are differant distances away from the sun, the greater the difference the longer it take
Do any planets have longer days or years?
No two planets in our solar system have the same length of day or length of year. Compared with Earth, these planets have longer years: Mars, Jupiter, Saturn, Uranus, Neptune. These have much longer days than Earth: Mercury and Venus. Mars has a day that's slightly longer than Earth's day. Depending on the particular definition of "day" that is used, two planets have a day that's longer than than that planet's year. They are Mercury (solar day) and Venus (sidereal day).
Are inner planets large or small?
The inner, or Terrestrial planets are very small in comparison to the outer, or Jovian planets. The smallest Jovian planet, Uranus, is 14.5 times larger than the largest Terrestrial planet, Earth.
Which planets have years longer than one earth year?
Jupiter, Saturn, Uranus, and Neptune have years longer than one Earth year. Jupiter's year is about 12 Earth years, Saturn's is about 29 Earth years, Uranus's is about 84 Earth years, and Neptune's is about 165 Earth years.
Why is the Earth's atmosphere so different from that of the other terrestrial planets?
The Earth's atmosphere is different from other terrestrial planets because it has a unique balance of gases, including oxygen and nitrogen, that support life. This is due to factors like the presence of liquid water, active geological processes, and the presence of living organisms that have shaped the composition of the atmosphere over billions of years.
Would a year on the planets take longer or shorter then an earth year explain?
It depends on the planet. The planets orbiting closer to the sun than earth (Mercury and Venus) have shorter years, because they have smaller orbits, and travel faster. The planets further from the sun (Mars, Jupier, Saturn, Uranus, and Neptune) have longer years because they have larger orbits and travel slower.
Why does it take the outer planets so long to orbit the Sun?
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
