Constellation positions please help, 10 points.?

In the northern hemisphere during September at 9pm you see a constellation in the east, whereabouts would it be at midnight? Why?



Where would you expect to see this constellation is December.? Why?



In September, you observed a planet as part of this same constellation. Would you expect to see it in the same position with the constellation in December? Why?



How would you know that you were seeing a planet with the constellation and not another star as part of the constellation?



A year later, at the same time when you observe the sky would you see the same constellation and planet in the same position? Why?Constellation positions please help, 10 points.?It would be higher in the sky by 45 degrees of altitude because of the rotation of the Earth



in December it would be further west in the sky at the same of day because Earths movement along its orbit around the sun makes stars rise 4 minutes and 53 seconds earlier everyday.



No, the planet would not be in the same location in the constellation in December as it was in September because the planet is moving along its own orbit, so planets location within the constellation shifts or it moves into a different constellation.



Planets move, with respect to stars, but stars in a constellation do not move or shift position with respect to one another over a few months. The constellation just rises earlier and sets earlier,



You would still see the constellation in the same part of the sky a year later, but the planet would be in a different constellation because of its orbital motion over Earth's year. The other planets have different "years" than Earth.Constellation positions please help, 10 points.?http://astronomyonline.org/Observation/C鈥?/a>

i tthink your question is like joke i mean like if you ask why the earth is spinning around its axis or is go around the sun. that is just physics. if the question was which constellation ok but why it is just about specific position of the obejct in specific rules of physcis and all about astronomy.Constellation positions please help, 10 points.?In the northern hemisphere during September at 9pm you see a constellation in the east, at midnight it will be 45掳 above the eastern horizon, halfway to the meridian. Every hour the constellation rises another 15掳 above the eastern horizon. The meridian is the line that goes from the southern horizon through your zenith to the northern horizon.

In December this constellation will at the meridian at 9 pm. The constellation will rise 2 hours earlier every month, stars rise just under 4 minutes earlier every day. These 2 hours mean that the stars that form the constellation are 30掳 higher above the eastern horizon every month. So after 3 months the constellation will be 90掳 above the eastern horizon, or on the meridian, the line that extends from your zenith (overhead) to both the northern and southern horizons.

If in September, you observed a planet as part of this same constellation, other than slow moving Saturn, you would you would see that it had moved by December. The planets are moving continually around the Sun. Saturn takes 30 years to orbit the Sun so it won't appear to have moved much in 3 months, but if you look closely Saturn too has moved with respect to the stars of the constellation.

You know that you were seeing a planet with the constellation and not another star because planets don't twinkle like stars do, are fairly bright and move with respect to the stars.

A year later, at the same time when you observe the sky you would see the same constellation in the same position but planet will have moved. Only Saturn and possibly Jupiter would still be in the same constellation, but in different positions.Constellation positions please help, 10 points.?
constellations move15degree per hour from east to west due to earths rotation./

after one year same month same time the same constellation will be there but not the planet./Planets have trheir own movement as they go round the sun indifferent periods.
