What's the difference between a sidereal year and a synodic year?
A sidereal year is measured based on the planet's position in space relative to the background stars. A synodic year is measured based on the planet's position relative to the star it rotates around (i.e. the sun) Here's an image that is pretty helpful in visualizing.
What is a sidereal month and why is it dfferent than a synodic month?
Synodic month is longer than Sidereal month because when the moon completes 1 revolution round the earth, it will not be a full moon as the earth also moves in its orbit
About how long does it take the moon to rotate on its axis?
The moon takes 29.5 days to complete one synodic cycle. This cycle is what we observe from earth, and it is the cycle we would measure from, say, one full moon to the next. However, by the time a synodic cycle ends, the moon has rotated a little more than 360 degrees. This is hard to grasp and takes some time and thought. The rotation of bodies that are orbiting other bodies always presents a need to distinguish between synodic and sidereal rotation. The true, 360 degree sidereal rotation of the moon takes 27.32 earth days. See links on the moon, and on synodic and sidereal periods. Note: Many erroneously conclude that since the same face of the moon always orients toward earth this means that the moon cannot be rotating. However, if you imagine observing from the north the orbiting of the moon around the earth (the moon does orbit the earth-- another idea that some people don't believe), the only way that the same face orients toward earth is for the moon's orbital and rotational periods to be the same. The moon is tidally locked with earth, and this is what causes the orbital and rotational periods to be the same. The face of the moon does in fact change a little due to the phenomenon called libration, a topic beyond the scope of the question. == ==Jeremiah Deem Tulsa - 27.322 days
How long does it taks earth to rotate?
One Day, or 24 hours. Twenty four hours is the rough and commonly understood period of rotation, since we know that a day of universal time is exactly 24 hours in length. But to be more precise, a sidereal rotation of the earth (exactly 360 degrees as observed from the distant stars) takes 23 hours, 56 minutes and about 4.1 seconds. To understand how this can be so, research the difference between sidereal and synodic periods of rotation.
Why is the lunar month longer than the number of days it takes to orbit the earth?
Because the Moon orbits the Earth whereas the Sun and stars do not. So the Moon has real motion apart from what the rotation of the Earth appears to give it. Thus the Moon rises in the East about 20 minutes sooner every day.
How many months have more than 4 Tuesdays?
5 months
How many days exactly in a year?
365.25 days. If you want a more exact answer you have to specify whether you mean the vernal equinox year, the sidereal year or the tropical year.
How many years does it take to make a hotel?
Many. It takes months to get the bills and everything taken care of, more months to build it, and even MORE months to get the furniture in, and so on.............
How many months are in B months?
It rather depends on what is meant by B months - more info is required!
What planets days is more than half as long as its years?
The "Solar day" on Venus. Or, the "Sidereal day" on Mercury.
What is the revolution of a planet?
If you are talking about bodies in the solar system, then revolution almost always refers to the orbiting motion of a body around another body. This is the motion that gives us the year on earth. The earth revolves around the sun once in about 365.25 days. Revolution can be a little more complex than this. A sidereal revolution is the orbit of a body as it is observed from the distant stars. Synodic revolution is a revolution as it is observed from the body being orbited, and it brings the orbiting body back to its starting point relative to the sun. These two orbital periods are not the same length. The phases of the moon follow the synodic period; the synodic period is longer than the sidereal period by roughly a day or two.
How many months in 186 days?
That's just a few days more than six months.
