Mercury and Venus both orbit the sun at less than 1 astronomical unit (AU). Mercury orbits the sun at an average distance of .387 AU (about 58 million km) and Venus orbits at an average distance of .723 AU (about 108 million km). Compare these distances to 1 AU which is about 150 million km, which happens to be the average sun to earth distance; which defines the astronomical unit.

∙ 12y agoThe astronomical unit (AU) is equal to the orbital distance of Earth. Mercury and Venus would be closer to the Sun.
Mercury - about 0.39 AU (46 to 70 million kilometers)
Venus - about 0.72 AU (107 to 109 million kilometers)

∙ 6y agoThat depends - for any planet its year is the TIME it takes to make one revolution of the Sun. Thus if you use this definition of a year, there are NO planets that take less than a year to orbit the Sun.
However, if by "year" you mean an Earth Year, then all planets closer to the Sun than Earth will orbit it in less than an Earth Year and all planets further out from the Sun than Earth will orbit it in more than an Earth Year.
Using the second case the two planets that take less time to orbit the Sun than does the Earth are Mercury and Venus.

∙ 7y agoMercury and Venus have shorter years than a year on Earth. This is because they are closer to the sun and the circumference of their orbits is smaller than that of Earth's. Mercury and Venus

Which planets have longer and shorter years than earth?
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.
Which planets have a year longer than the Earth?
All the planets further away from the sun than Earth is
Which planets have years longer than one earth year?
All planets with a greater orbit than the Earth.MarsJupiterSaturnUranusNeptune
What planet's year is shorter than its day?
Venus Not Uranus
Can a planets day be longer then its year?
Yes. In fact, Venus has a longer day than its year.
What planets have a shorter year than mercury?
None.
This planets year is shorter than its day?
Venus
How can a planets year could be shorter than its day?
hmmm i dont know
How does a year on earth differ with other planets?
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.
Why is a year on Mercury shorter than other planets?
Because it has less distance to travel around the Sun.
Which planets have longer and shorter years than earth?
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.
Would a year on the planets take longer or shorter then an earth year explain?
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.
Which planets year is one year longer than earths?
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
Are inner planets large or small?
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.
What causes earths years to be shorter than Jupiter's years?
Well, we are closer to the sun, closer then Jupiter, so it makes our revolution shorterbecause we have a shorter distance to travel, hence Jupiter having a longer year then Earth.
What is longer than a season but shorter than a year?
A half-year.
Would a year on the planets nepture be longer or shorter than an earth 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.
