Mars. The further out from the sun, the longer a planet takes to revolve round the sun.
For example, Pluto's orbit takes over 200 (Earth) years.
One year on Mars is about 687 earth days compared to the the 365 days in a year on Earth.
One Mars year is about 687 Earth days or 1,89 Earth year.
99 days on earth is one year on mars
If you mean unit of time, then yes. A second on Earth is the same as a second on Mars, as is a minute, or an hour. Mars' length of day, however is slightly longer than an average Earth day because it rotates slightly slower than the Earth. A Martian year is also longer than a year on Earth because its orbit around the Sun is longer. One orbit around the Sun for Mars takes a little less than two Earth years.
Mars orbits farther from the sun,tthan Earth does, meand its orbital circumference is longer. Additionally, the farther out an orbiting object is, the slower it travels. So, to complete one orbit, Mars has to travel farther than Earth does and at a slower speed.
A day on Mars (the time it takes to rotate on its axis) is 24.62 hours, just slightly longer than a day on Earth.A year on Mars (the time it takes to go around the Sun) is 686.97 days, almost 2 of our Earth years.for more information, See other related questions, e.g. how long is a day on mars?=]
The length of year on Mars is 686.98 Earth days or 1.88 Earth years.
If you are speaking of one orbit around the sun, about 2 earth years. If you are using Earth's calendar, one year is one year. (note it's rotation on it's axis is a little more than one Earth day - 24.6 hours) on mars there is only a little time difference if compared to the earth if on earth 7:00AM than on mars it will be 7:10AM!!
A 'year' is the time it takes for a planet to orbit the sun. In the case of earth, this is 365 and 1 quarter days. That is why a year lasts for 365 days and every fourth year ( a leap year) we add up all the odd quarter-days to make an extra day which we put into February - as February 29th. Mars, however, takes 687 (to the nearest day) earth days to go round the sun, so a Martian year is 687 days long - or 1.88 earth years.
Jupiter has a longer year (about 4300 Earth days) than Mars (687 Earth days) because it is much further away from the Sun, and so has a longer distance to travel to complete one orbit (and it also goes more slowly as a result of the distance)
It orbits the sun about 1.88 times. Therefore, a Martian year is about 10½ months longer than an Earth year.
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
