Planets travel round the Sun, but all orbit in different speed and length.For example;Earth: Orbit round the Sun=364 1/4 daysNeptune: Orbit round the Sun= 164 years 288 daysSaturn: Orbit round the Sun= 29 years 167 days
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and the Dwarf Planets Pluto, Eris, MakeMake, Ceres and Haumea. With the possibility of a Super Giant Planet called Tyche out in the Oort cloud, that is possibly 4 times the size of Jupiter. (This has not been confirmed as of now, possible release date of confirmation will be this year 2011)
Yes, a year is the time it takes a planet to complete one orbit around the sun. This is also known as the orbital period. Different planets have different orbital periods based on their distance from the sun.
The 4 largest planets in order from biggest to smallest are:JupiterSaturnUranusNeptune
The inner planets
The rocky planets
The 4 smallest planets are also the 4 most inner planets: Mercury, Venus, Earth and Mars.

There are no planets in the asteroid belt. One of the new IAU definitions of "planet" is that a planet will have cleared its orbit of other objects. There are four planets that orbit closer to the Sun than the asteroid belt; these are Mercury, Venus, Earth and Mars.

It takes the Earth 365.25 days to orbit the sun once. This orbital period is governed by the planets distance from the sun, and the mass of the Sun and Earth. Kepler found that the square of the period, P, is proportional to the cube of the semi-major axis, a (P2 = ka3).
The inner planets
It takes about 365.25 days.
Mercury is both the smallest inner panet, and the smallest planet in our entire solar system.
Pluto is different from the inner planets in that it has not cleared it's orbit from asteroids.
