Every planet's year is longer than 365 days except for Mercury and Venus. Earth's year is aproximately 365.25 days, people just combined them for an extra day every 4 years.
Neptune
Mars
A planet with a day longer than its year is called a "retrograde" or "tidally-locked" planet. This means that its rotational period is longer than its orbital period around its star. This phenomenon occurs when gravitational interactions with a nearby celestial body, such as a moon or a star, slow down the planet's rotation, causing it to have a longer day than year.
Mars, with a revolution period of 24 hours and 38 minutes.
All planet's years are longer than their days except for Venus.You probably meant to ask which planet's day is longer than its year, and the answer is Venus.
None, unless you are talking about the dwarf planet Pluto in which the planet's day is longer than it's year.
No planet in our solar system has days longer than one Earth year. Venus has the longest day -- it's 243 Earth days.
Venus!
Venus
Mars has a longer year than Earth (about twice as long) and its day is 24 hours and 38 minutes long.
On the planet Venus - it takes longer for Venus to make one rotation than it does for it to go around the sun once, so Venus' day is LONGER than it's year. Imagine that?
Venus "sidereal day" is longer than its year. Mercury's "solar day" is longer than its year. However, there is no planet in our solar system with a day longer than our year on Earth.
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).
