What determines the length of day on a planet?
How long it spins on it's axis
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.
The spin of a planet or moon as seen from above a planets pole is called its?
A planet's rotation on its axis determines the length of its day.
What is the astronomical event that happens twice a year when the earth's axis is inclinded neither towards?
The astronomical event you are referring to is known as an equinox. It occurs twice a year, around March 20th and September 22nd, when the Earth's axis is not tilted towards or away from the Sun, resulting in nearly equal lengths of day and night worldwide.
What is a leap year and why are they necessary?
The real, or astronomical, year has a length of a little less than 365.25 days. To have a full number of days in a year, the length of the year is usually set at 365, and every 4 years, an extra day is added. Thus, on average, the length of the calendar year matches the astronomical year; an important astronomical event like the Spring equinox (for the Northern Hemisphere) will maintain its date - approximately - at March 20 or 21.The real, or astronomical, year has a length of a little less than 365.25 days.

spinning

What determines the first day of spring?
The first day of spring is determined by the vernal equinox, which occurs around March 20th in the Northern Hemisphere. This is when day and night are approximately equal in length, and it marks the beginning of spring.
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 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.
What determines a week?
A week is a seven day cyclical period, used to divide the length of a month into smaller parts
What determines the length of a day on earth?
the time it takes the earth to spin around on its axis
What are the astronomical importance of zodiac signs?
One reason is that the first day of each season arrives when the sun reaches 0 degrees of the four cardinal signs. That is an astronomical event. Those signs and seasons are:Aries for SpringCancer for SummerLibra for AutumnCapricorn for Winter
