How many martian days are in a Martian year?
541650
Very good question.  I went searching and came up with this:\n\nBTW, the person that answered 687 is correct for EARTH days, not MARS days.  It appears to be closer to 668.6 Martian days.

That depends on a lot of factors, including random supergiant meteors or human stupidity. But at the least, when the sun becomes a red giant (when the hydrogen in the inner core has all been converted to helium) in about 6 billion years, it will encompass the entire orbit of Mars. That pretty much suggests no hope for Earth beyond that point.

Dave_Stark\n23 seconds ago\n\n\n \n The average distance from Mars to the Sun is 1.52369 astronomical units. One astronomical unit (AU, the average distance from the Sun to the Earth) is 1.49597870E11 meters.\n\nConverting those numbers, then, means that Mars is:\n\n1.52369 * 1.4959787E11 meters = 2.27941E11 meters, or, converting into English units:\n\n141,635,833 miles (on average -- remember that the orbits of the planets around the sun are not circular, but elliptical)

they don't\na year is an amount of time defined by man equal to about 365.25 days, comprised of 24 hours each. a year could have just as easily been defined as a round rubber object you put on your vehicle to make it roll\na year on saturn or mars or mercury is a year.

No. A day is a measured period of time and can be a thousand years or many thousands of years. The Bible's creative days allows for thousands of years of time each. Reasonably, each "day" of creation is the same length as the others, even as the days of the week are of equal length. So, the length of each of the seven "days" of creation is about 7,000 years, according to Bible chronology. Note, that Jehovah God proceeded to rest on the seventh day, and their is no indication the "day" had concluded. The "day" of God's rest continues now nearly 6,000 years. Also, their would be a thousand-year reign of Christ, yet to come.--Revelation 20: 1-6. For more information, go to this website: www.watchtower.org.

365.256366 Earth days around the Sun, if that's what you mean. Or 24 hours around its axis.

The diameter of Mars at its equator is 6,794 kilometers (4,222 miles), compared to Earth's 12,756 kilometers (7,928 miles).  This is 53% of Earth's size.\n\nIt also has about 30% of Earth's gravity, 11% of Earth's mass, and 1% of Earth's atmospheric pressure.  Oh, and it has 0% of Earth's population, but that statistic is the most likely of any of them to change.

In a non leap year, 365 days, there are 31, 536, 000 seconds in a year.  \n\nHowever, the answer you are looking for could be ...12!\n\nJanuary 2nd, February 2nd, March 2nd...etc.

If you take leap years into consideration, the average year contains 525,948.766 minutes.  A year with just 365 days contains 525,600 minutes.

The Mayans, about 2000 years before the Romans. \nThe Mayan year is called a Haab and is 365 days, which is also represented by the 91 step pyrimids (91steps x 4 sides = 364 + the top = 365)

Mars takes 688 Earth days to orbit the Sun once.  This is a bit less than two Earth years (730 days), or not quite 6% less.  So about ten orbits, depending on when in 1987 you want to count from..

Leap year.\n\nA leap year has 366 days.

The number of days in a year is about 365.25, but is closer to 265.242..., so leap years are less often than every four years.
