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.
What else can I help you with?
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.
Why do planets closer to the sun have a shorter year?
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
Which two planets have the same length of day which is shorter than an earth day?
The two planets that have the same length of and Earth day but shorter than a Earth day are Neptune and Uranus because a Earth day on Neptune is 18 hours and 30 minuets Earth time, And Uranus is 17.24 hours. Thus Neptune and Uranus is closest to an Earth day being below 23 hours and 56 min (24 hours rounding).
Why is a day shorter than a year?
Because 365 days make a year, so therefore, days are smaller.
Eath has a longer year than mercury or Jupiter?
No, Earth actually has a shorter year than Jupiter. Earth takes about 365.25 days to complete one orbit around the sun, while Jupiter takes approximately 11.9 Earth years for a single orbit. Mercury has the shortest year of all the planets in our solar system, completing an orbit around the sun in about 88 Earth days.
This planets year is shorter than its day?
Venus
What planets have a shorter year than mercury?
None.
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.
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 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.
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.
Why do planets closer to the sun have a shorter year?
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
What is longer than a season but shorter than a year?
A half-year.
How many months are considered shorter than a year?
-- All of them are. -- Any number of months less than 12 is shorter than 1 year.
