Negative means the planet spins in the direction opposite of Earth.
Earth has a rotational period of one day by definition.
Note that because the gas giants have no surface, different parts rotate and different speeds. The listed speed is the average.

Days on other planets depend on the speed of its revolution on its axis, this could take any amount of time, from a few seconds to many Earth years if the planet is massive. The length of a planets year, however, depends on its orbit around its parent star (Given that it has an orbit.) and as we know, one complete orbit is a year. Orbits can vary in range, some planets can be very close to its parent star like the planet Mercury. Others range from 1 AU (Earths distance from the sun) to over 1000+ AU which makes these distant planets years very long. Their orbits can take up to 3000+ Earth years.
Within the Solar Sytem:For all planets, a year is the time it takes for the planet to revolve around the Sun once. the further the planet from the Sun, the longer the year.
the year length of planet is 87.9 days
There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplers third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun.
Mercury.
Rotational time of the planets is random (the length of the planet's day), but the outer planets do spin faster than the inner planets.
distance from a source of light and how long it takes to orbit that source
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.

A planets year is the time it take to make one orbit of its star.
84 known moons and planets
Typically, this length of time is called a "year". Each planet's year is a different length than that of the other planets and increases as the planet is further from the Sun.
There is no constant year length for planets, dwarf type or otherwise. A planet's period (year length) depends entirely upon how long it take to orbit its star. Depending on the planet and its situation, that might take a matter of a few days, or a few years, or even centuries.
The length of a year for a planet is the amount of time it takes for the planet to make a complete revolution around the sun. For the Earth, this is about 365 1/4 days. The length of time for other planets in our solar system to revolve around the sun is can be longer or shorter.
Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.
No. Every planet has different length years. The farther a planet is from the sun, the longer year it has. Mercury's year is only 88 of our days. Earth's year is exactly 1 year long. Jupiter's year is about 12 of our years, and Pluto's year is 248 of them.

60. The length of the year and the length of the day on Jupiter will differ from that of Earth because a year is the length of time it takes to complete a circuit around the sun and a day is the length of time it takes to rotate on its axis. However, hours, minutes, and seconds are units of time that do not change on other planets.
The outer planets take longer to go round because (i) they are further away and (ii) they move more slowly because the Sun's gravity is weaker out there.
