A year is how long it takes Earth to orbit the Sun, and for all practical purposes, you may regard that as 365 and 1/4 days. Other planets take different time periods to orbit the Sun.
It takes Earth 1 year to orbit the Sun. It takes Pluto 248 years to do the same. The time depends on the distance from the sun and, therefore, the length of the orbit.
Alpha Centauri does not orbit the sun.
