the time it takes the earth to spin around on its axis
What else can I help you with?
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.
What movement of the planet makes one day as a unit of time?
It is the rotation of the planet one complete revolution that determines the length of a day.
What regulates the length of one day?
The answer is surprising. Historically, it is hard to avoid the fact that a day is defined by the apparent movement of the sun. However today, because there are measurable changes in the earth's movements, the day is regulated by extremely accurate clocks that keep time according to a defined and unchanging second. Cesium clocks (or perhaps an even more highly developed technology) are actually regulating our modern concept of day.
What is the length of one day in venus?
243 earth days
One complete turn of a planet on its axis?
A complete turn of a planet on its axis is known as a "day." This rotation determines the length of a day on that planet. For Earth, it takes approximately 24 hours to complete one full rotation.
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
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.
What is it called when a planet complete spin on its axis?
A planet completing one full rotation on its axis is called a "day." This is what determines the length of a day on that planet.
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
What is the responsible length of one day?
The planet's rotational period is the only thing that determines the length of one day. (mostly - it also is dependent on how fast the planet orbits the sun. If it orbits quickly, the "day" will be measurably less than the time for one full rotation.)
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.
