i think its 10.656 earth hours
The length of one sidereal Earth year is 3.39% the length of one sidereal Saturn year. In other words, the length of one sidereal Saturn year is 29.5 times the length of one sidereal Earth year. (A sidereal year is the time between alignments of the sun, the planet, and a distant fixed star.)
The length of a Martian day is equal to 1.027491204 Earth days. The length of one sidereal Martian year is equal to 1.880791 sidereal Earth years.
Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.
Yes.
It is about 117 Earth days (for the "solar day") or 243 Earth days (for the "sidereal day").
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
243 days on earth
A day on Saturn is 10 hours, 39 minutes. There was a six minute difference between Voyager and Ulysses measurements of the Saturn day.
The sidereal day is the period of Earth's axial rotation. It's the same at every place on Earth on every day of the year. It's 23hours 56minutes 4.1seconds long. (seconds rounded)
243 Earth days is the rotation period of Venus. That's its "sidereal day" length. The other main definition of a "day" is called a "solar day". For Venus that's only about 117 Earth days in length.
A mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours.
A day on the moon is 29.5 Earth days. The moon takes 27.3 days to fully orbit the Earth. This is called a sidereal day.
