What determines the length of day on a planet?
How long it spins on it's axis
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 planet length in day is close to the length of earths day?
Mars.
Length of a day of asteroid belt?
A day is what you experience on a planet that is spinning. Each time the asteroid turns so you face the sun - that's another day. So it depends on if the asteroid you are focusing on is spinning, and how fast.
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.

What type of planetary motion determines the length of the day?
spinning
What determines the length of day on a planet?
How long it spins on it's axis
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 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
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 determines the first day of spring?
The Vernal Equinox determines the first day of spring. The Autumn Equinox is what determines the first day of fall.
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.)
What day was Feb17.1972?
It was the day an important astronomical question was raised in nasa
Is there a full moon on solstice day?
Full moons and solstices have nothing to do with one another. Each astronomical event is independent of the other. While there can be a full moon on a solstice, it would be purely accidental.
