How many days is in a year on plant Saturn ?

10,756 (nearly 29 and a half earth years).\n\nI knew that knowing useless fact would one day come in useful!!

As you know a year is a full rotation of earth around the sun and initially month was the full rotation of moon around earth. Sumerians created their first calendar using this information. The problem with this is that a full rotation of moon is 29.5 days then 12 months make just 354 days. This is shorter than a year. Therefore, a synchronization was needed. In order to be able to synchronize their calendar people added another 13th month in every three years. However a standardization could not be achieved, different people added the 13th month at different times. This created a lot of problems especially for trade and contracts. As a result of this experience people thought that something is bad about 13 and they changed their calendar in such a way that months are no longer equal to the full rotation of moon around earth. There are still some calendars with a month equal to the full rotation of moon. For example, "honey moon" is a saying from those old days, because it was the tradition that father of the bride provided a fermented honey drink to the groom for a full month after the marriage.

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.

Saturn is the 6th planet from the sun.

365 except on leap years; then it's 366. (technically it's like 365.25 days a year. we just save up the extra 0.25 until we have a whole day to spend.)

Summer on Uranus lasts 21 years using the definition of 4 equal seasons. However, the period between vernal (spring) equinox and autumnal equinox is actually 42 years. This year is the vernal equinox.\nI quote:\n"The extreme tilt of the axis of Uranus has important implications for the weather on that planet. Consider how the seasons vary during the course of one uranian year:\n\n    * Winter solstice (which last occurred in 1985 AD):\n      The north pole is pointed almost directly away from the Sun.\n      The northern hemisphere experiences perpetual darkness.\n      The southern hemisphere experiences perpetual sunlight.\n    * Spring equinox (2006 AD):\n      The rotation axis is perpendicular to the Uranus-Sun direction.\n      From any point on Uranus, the Sun rises in the east\n      and sets in the west 8 1/2 hours later.\n    * Summer solstice (2027 AD): The north pole is pointed almost directly toward the Sun.\n      The north experiences perpetual sunlight.\n      The south experiences perpetual darkness."\n\nSource: http://users.zoominternet.net/~matto/M.C.A.S/notes_uranus__neptune.htm

It was 63 at the last census. Saturn has 56, Uranus 27, Neptune 13, Mars 2 and Earth 1 making 162 planetary moons in all,\n\nFirst to be discovered (in European culture)  were Io, Callisto, Europa and Ganymede in January 1610, by Galileo. But the Chinese astronomer Gan De is reported to have seen one of the moons of Jupiter (possibly Ganymede) with his naked eye in 364 BC,  Nearly 2,000 years earlier.\n\n15 of the moons still lack a name, and only have a designation. In order outwards from the planet, with their orbital periods, the 63 are as follows:\n\n1 Metis 7h 4m 29s\n2 Adrastea 7h 9m 30s\n3 Amalthea 11h 57m 22.67s\n4 Thebe 16h 11m 17s\n5 Io 1.77 days\n6 Europa 3.55 days\n7 Ganymede 7.15 days \n8 Callisto 16.69 days \n9 Themisto 129.87 days\n10 Leda 241.75 days \n11 Himalia 250.37 days \n12 Lysithea 259.89 days \n13 Elara 261.14 days \n14 S/2000 J 11 287.93 days \n15 Carpo 458.62 days \n16 S/2003 J 12 482.69 days \n17 Euporie 538.78 days \n18 S/2003 J 3  561.52 days \n19 S/2003 J 18  569.73 days \n20 Thelxinoe 597.61 days \n21 Euanthe 598.09 days \n22 Helike 601.40 days \n23 Orthosie 602.62 days\n24 Iocaste 609.43 days \n25 S/2003 J 16 610.36 days \n26 Praxidike 613.90 days \n27 Harpalyke 624.54 days \n28 Mneme 627.48 days \n29 Hermippe 629.81 days\n30 Thyone 639.80 days \n31 Ananke 642.02 days \n32 S/2003 J 17  672.75 days\n33 Aitne 679.64 days \n34 Kale 685.32 days \n35 Taygete 686.67 days \n36 S/2003 J 19  699.12 days \n37 Chaldene 699.33 days\n38 S/2003 J 15  699.68 days\n39 S/2003 J 10  700.13 days\n40 S/2003 J 23  700.54 days\n41 Erinome 711.96 days \n42 Aoede 714.66 days \n43 Kallichore 717.81 days \n44 Kalyke 721.02 days \n45 Carme 721.82 days \n46 Callirrhoe 722.62 days\n47 Eurydome 723.36 days\n48 Pasithee 726.93 days \n49 Cyllene 731.10 days \n50 Eukelade 735.20 days \n51 S/2003 J 4 739.29 days  \n52 Pasiphaë 741.09 days \n53 Hegemone 745.50 days \n54 Arche 746.19 days \n55 Isonoe 750.13 days \n56 S/2003 J 9  752.84 days\n57 S/2003 J 5  758.34 days \n58 Sinope 762.33 days \n59 Sponde 771.60 days\n60 Autonoe 772.17 days \n61 S/2003 J 14 776.02 days \n62 Megaclite 792.44 days \n63 S/2003 J 2  1077.02 days

Actually there are 364 + 1/4 days in a year. This has to do with the time that our Earth takes to complete one erbit around Sun. Now we have an arbiterary time period called week which has 7 days. So we have a normal year of 7 x 52 = 364 days. This leaves us with one 1/4 day per year left unaccounted. To make up for it, we have a leap year (365 days, 29 days in February) every four years.

The importance of 60 comes from the Babylonians used a base 60 number system as compared to our base 10 system. 60 and 6x60 = 360 were very natural numbers for them to work with. They used a 360 (6X60) day calendar as opposed to our 365 day calendar. The ancient astronomers would have noticed that it takes 365 days for the sun to move (about our fixed Earth) past the stars that appeared to be fixed to an external heavenly sphere, and return to where they started. The choice of 360 days for a year may have been a compromise between a 365 day solar year and a 354 day lunar year, (consisting of 12 months of 29.5 days each).

It takes about 365.2422 days to orbit the sun (i.e. a solar year). If we have a year be 366 days every four years, that averages out to 365.25 daysper year. This is still a bit large, so we declare 3 of the four century marks to *not* be leap years. That then gives an average of 365.2425, which is close enough for most purposes.\n\nSpecifics: Every year that is divisible by 4 is a leap year *except* those ending in 00. These are leap years only if divisible by 400.

According to my STARRY NIGHT astronomy software, Saturn is currently 9.625au from us. \nThe reason it varies is because the planets orbit around the sun aren't 100% perfect circles, and go round at different speeds, so aren't at a constant distance.

Saturn is the sixth planet from the Sun. It is a gas giant, the second-largest planet in the solar system after Jupiter. Saturn has a prominent system of rings, consisting of mostly ice particles with a smaller amount of rocky debris and dust. It was named after the Roman god Saturn. Its symbol is a stylized representation of the god's sickle

A day on Venus is longer than a year because it spins the other way.\nSaturn has rings, and so does Jupiter and other giants!\nMars sometime seems to be going backward in the sky!\nUranus spins on its side (the same pole always points to the Sun)\nMercuray and Venus have no moon, and Jupiter and Saturn have new ones being discovered all the time.\nPluto is no longer a planet because it's too small and its orbit is too oval.

mercury has a day that last 58 of our days, so the same side is away from the sun for very long periods of time.  the same way that the earth gets cold at night and warmer during the day, the same thing happens to mercury, escept that each night last for the equivalent of 29 of our days (on average).  the fact the mercury has negligible atmosphere greatly exacerbates this effect

It depends on the season. The current average lengths are:\nWinter: 88.994 days\nSpring: 92.758 days\nSummer: 93.651 days\nAutumn: 89.842 days \n\n(These values change slowly over time, as the position of the perihelion of Earth's orbit changes.)\n\nThe differing lengths of the season enabled ancient Greek astronomers to accurately measure the eccentricity of Earth's orbit as far back as the 2nd century BC.
