How do I find out the moon's diurnal motion on a given day?
471913
The daily path of an object on the celestial sphere, including the possible part below the horizon, has a length proportional to the cosine of the declination. Thus the speed of the diurnal motion of a celestial object is this cosine times 15 °/hr = 15'/min = 15"/s, i.e. (compare angular diameter):\n\nup to a Sun or Moon diameter every two minutes \nca. four seconds for the largest planet \n2000 diameters of the largest stars per second

Either get a starguide book or google for on the internet and it will tell you the position of the stars and planets in the sky.  It should let you figure out there exact position for the sky where you live any for any day and time you want to look.  There are also many programs that you can get for your computer that do that and more!  Google has great maps of the moon and there are many astronomy web sites or forums where you can learn lots about the planets, stars, how to use your telescope and lots of other cool stuff!  Hope you have fun with your new toy!!

it depends on where in the world you are.\n\ngo to www.timeanddate.com and find your location (or one that is close to you).  it will show you the time and day.

The moon's distance from earth is about 240,000 miles.  The orbit is roughly circular (only 5% eccentricity), so 2π*240,000 = 1.5 million miles is the circumference.  The moon travels this distance in 29.5 days, so its speed is about 51,000 miles per day or about 2100 miles per hour.

if it is extemely bright, then it is most likely the planet Jupiter. The moon moves a lot each day, so you need to say exactly what day and time you saw it.

The phases of the moon are the same around the world. What varies is the rise and set time. The US Naval Observatory is a great site for this.

Of course, that won't help you figure out how high it is in the sky each night at a specific time if you are trying to fill in a moon observing lab that you failed to do.  \n\nI will help you this much: the moon rises 50 minutes later each night (about 12 degrees further east at the same time each night) and is more or less directly overhead at midnight when it is full.  If you figure out where it should be at a particular time each night, you deserve credit for the lab.

The leonids peak 04:35 and 05:00 UT on 19th November, so I guess it should be around 2035 (8:35pm) and 21:00 (9.00pm)Pacific Standard Time on 18th November.\n\nBut thats not important. All you have to do is to start your observation, from a clear dark sky, around or after midnight and try to keep a watch the skies in the eastern direction. You will be rewarded with meteors. The frequency will increase as day break approaches.\n\nBest wishes

The moon's orbit is nearly circular and traverses 13.2 degrees along this orbit over the course of a day. Its orbital velocity varies from 0.964 to 1.076 (mean 1.023) kilometers/sec (multiply the mean by 86,400 to get the number of km/day traveled. Multiply by 0.62137 to convert to miles).

Yes, the moon goes around the Earth at a much slower rate (28 days) than the Earth spins around once (24 hrs).\nClick on the link to the animation below. Notice how the Earth spins while the part of the moon facing us changes.
