One Earth rotation relative to a star besides the sun (often measured by Polaris), stellar time, takes approximately 23 hours, 56 minutes, and 4 seconds. One Earth rotation relative to the vernal equinox (sidereal time) is takes approximately 23 hours, 56 minutes, and 4.091 seconds. Earth's rotation relative to the sun's (Sol) apparent position in the sky (solar time) appears to change with the month, varying as much as 30 seconds.
What else can I help you with?
The length of an Earth day is determined by the time required for approximately one?
The length of an Earth day is determined by the time required for approximately one full rotation of the Earth on its axis. It takes approximately 24 hours for the Earth to complete one rotation, resulting in a day-night cycle. This rotation period is the basis for our concept of a day.
The length of a day is based on?
The length of a day is based on the average period of time required for one rotation of the earth on its axis.Read more: The_length_of_a_day_is_based_on
Length of the Moon's day?
The Moon's day, or "lunar day" lasts about 29.5 Earth days, which is the time it takes for the Moon to complete one full rotation on its axis. This is the same amount of time it takes for the Moon to complete one orbit around the Earth.
Which planet has the same length day as earth?
No planet really does have a day "the same length as Earth", but Mars definitely has the one that's the closest. The day length of Mars is just over half an hour longer than Earth's.
Mars length of one day?
Mars has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
What controls the length of a day?
The length of a day is primarily controlled by the rotation of the Earth on its axis. The Earth takes approximately 24 hours to complete one full rotation, which determines the length of a day. Variations in the Earth's rotation speed can result in minor changes in the length of a day.
How long is a day on the planet in your earth day?
To be exact the Earth day is not 24 hours it is 23 hours 56 minuets and 4 seconds. That's the Earth's rotation time. Yes, that's the length of the "sidereal day". However the length of the "solar day" IS exactly 24 hours. That's the time for the Sun to complete one apparent journey around the sky. Comment: That answer is for the Earth. Unfortunately, it's not clear which planet this question is about.
What is the length of one day in venus?
243 earth days
What is mercurys length of the day?
One day on Mercury is equal to 1407.6 Earth hours.
How many times does earth spin on its axis a day?
One spin is what measures the length of one day

How many earth days does it take for one day on Mars?
Mars's day-length is close to that of Earth: 24.7 hours. As such, there are 1.03 Martian days per every one Earth day; or, alternatively, 0.97 Earth days per every one Martian day.
How are the length of the day and year related to Earth's movement through space?
WELL THE LENGTH OF THE DAY IS RELATED TO THE Rotation AND REVOLUTION OF THE PLANET BECAUSE THE PLANET HAS LENGTH BUT IT MIGHT NOT HAVE THE SAME THING AS OUR LENGTH AND IT HAS THE SAME ROTATION AND REVOLUTION.WHAT DO YOU YOUNG GUYS AND LADIES THINK ABOUT MY ANSWER ?PLEASE COMMENT ON IT I WILL APPROACHED THAT BY.
What would happen to the length of a day if the rotations sped up?
It takes 24 hours (the length of one day) for the Earth to rotate once. If the rotation sped up, the length of a day would shorten.
How many earth days is 18 hours?
Eighteen hours is less than twenty four, which is the length of one earth day. Eighteen hours is three-quarters of one earth day.
