Usually the solar day is the longest.
The other two are very similar in length to each other.
For example, the solar day on Earth is about 4 minutes longer than the other two "days".
However, for the planet Venus the solar day is the shortest. That's because
Venus has retrograde rotation.
What else can I help you with?
Is a sidereal day longer or shorter than a solar day?
The Sun crosses the meridian (the imaginaryline in the sky from due north to due south and passing directly overhead) at solar noon. The period between two successive solar noons is a "solar day". When you reckon the period of time between two successive meridian transits of a distant star, or the vernal equinox, that is a "sidereal day". In simple terms the sidereal day is the rotation period of a planet.
Why is the solar day on Mercury longer than earth's solar day?
1) Mercury rotates very slowly. It takes Mercury about 58.6 Earth days to rotate just once. That's the length of the sidereal day. 2) Mercury has a solar day of about 176 Earth days in length. So, Mercury's solar day is much longer than its long sidereal day. That's because of the combination of slow rotation with a short orbital period (about 88 Earth days).
What planet has the second shortest 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.
The length of one day in Venus or even a year?
It takes Venus about 243 Earth days to complete one rotation on its axis, making a day on Venus longer than a year on Venus (225 Earth days). This means that a day on Venus is longer than a year on Venus.
What is the length of a day for all of the planet to planet?
There are two main definitions of "day" for a planet:1) Sidereal day. That's the time taken to rotate once.2) Solar day. That's the time taken for the Sun to complete one apparent journeyaround the sky. Usually it's given as the "mean solar day", which is the average value.The solar day depends on the planet's orbital motion, as well as its rotation.Here are the details, with slight approximations:Mercury : sidereal day, 58.65 Earth dayssolar day, 175.94 Earth daysVenus: sidereal day, 243.02 Earth dayssolar day, 116.75 Earth daysEarth: sidereal day, 23.934 hourssolar day, 24.000 hoursMars: sidereal day, 24.623 hourssolar day, 24.660 hoursFor these planets both days are nearly the same length:Jupiter: 9.92 hoursSaturn: 10.66 hoursUranus: 17.24 hoursNeptune: 16.11 hours
What is longer a sidereal day or solar day?
a solar day
How a solar day is differ from a sidereal day?
A solar day is 24 hours whereas a sidereal day is 23 hours and 56 minutes
How is a solar day different from a sidereal day?
A solar day is 24 hours whereas a sidereal day is 23 hours and 56 minutes
How many hours is a Mars day?
24 Hours and 37 Minutes Improvement: That's the "sidereal day". The "solar day" is about 2 minutes longer.
How long are days on earth?
There are different frames of reference: 1 True solar day 2 Mean solar day 3 Stellar (sidereal) day If you calculate 60 seconds times 60 minutes times 24 hours you get 86 400 seconds.
Is a sidereal day longer or shorter than a solar day?
The Sun crosses the meridian (the imaginaryline in the sky from due north to due south and passing directly overhead) at solar noon. The period between two successive solar noons is a "solar day". When you reckon the period of time between two successive meridian transits of a distant star, or the vernal equinox, that is a "sidereal day". In simple terms the sidereal day is the rotation period of a planet.
Which is used for our clocks Sidereal or solar day?
Solar day is typically used for our clocks and calendars, as it is based on the Earth's rotation relative to the sun. Sidereal day, on the other hand, is based on the Earth's rotation relative to distant stars.
Why the length of day appears to be 4 minutes longer than it actually is?
There is more than one definition of "day". On the Earth one "day" is about 4 minutes longer than the other. Both are correct. The "solar day" is 24 hours, but the "sidereal day" is about 4 minutes shorter. The sidereal day is the time the Earth takes to rotate once. The solar day is the time taken (on average) for the Sun to complete its apparent daily journey around the sky. The solar day is a bit longer because the Earth orbits the Sun and that affects the position of the Sun in the sky. The Earth needs to rotate for about 4 minutes more than the "sidereal day" to have the Sun in the same place in the sky again.
The fact that the Earth has moved along its orbit in the time it took to rotate once is the reason for?
the difference between a solar day (based on the position of the Sun) and a sidereal day (based on the position of the stars). Because the Earth has moved in its orbit, it needs to rotate a little longer to bring the Sun back to the same position in the sky each day.
Is the difference between the length of a solar and sidereal day caused by revolution?
Yes.
What fraction of a year in a day?
A solar day is approx 100/36526 solar days.
How long is day on mars?
a day on mars is 24 hours and 37 minutes slightly longer than an earth day. Edit : Yes, but that's the "sidereal day" or rotation period. There's also the "solar day" which is about 2 minutes longer.
