hmmm i dont know
Venus
None.
A year on Earth is longer than it is on two other planets, and shorter than it is on the remaining five. The farther a planet is from the sun, the longer its year is.
Because it has less distance to travel around the Sun.
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.
Planets closer to the sun than Earth orbit the sun in less than one year (Mercury and Venus), while planets further out from the sun than Earth take longer than a year (Mars, Jupiter, Saturn, Uranus and Neptune). The further out you go, the longer it takes to orbit the sun.
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.
Their orbit is a smaller circle than the ones further out, and as long as they are moving at relatively the same speed they will complete each orbit faster. Check out the planetary orbits link, it gives a really cool description and moving diagram
A half-year.
if you mean neptune, then yes. the year would be a lot longer because neptune is alot further from the sun than the earth. so therefore, neptune will take longer to orbit the sun than the earth.
-- All of them are. -- Any number of months less than 12 is shorter than 1 year.
177 days shorter on mercury than the earth
