If you observe the position of a star at a fixed time everyday, how many degrees higher will it appear after 3

Question

how many degrees higher will it appear after 30 days

Answer 1

degrees higher? you can tell how hot a sta iz just by lookin at it?

Answer 2

It depends on what star you're talking about and what latitude you're standing at.

If you're talking about the North Star, its elevation above the horizon will always be equal to your latitude, regardless of what time you observe it. So the answer to the question would be 0.

At the other extreme, you could be standing at the equator and observing a star that passes directly overhead. In the course of a year, such a star will will follow an arc of a full 360 degrees if viewed at the same time every night. (Half the time you won't be able to see it, because half of the 360 degrees will lie below the horizon.) So that is a little less than 1 degree each day. After 30 days, its elevation will have changed by a little less than 30 degrees. And depending on where the star appeared the first night, the 30 degrees could make it higher or lower in the sky (or even make it disappear below the horizon).

For any other latitude and star (i.e., any situation OTHER than the equator and a star that passes directly over the equator), the answer is somewhere between 0 and 1 degrees per night, or between 0 and 30 degrees per month.

If this is a homework problem and the teacher insists that the answer is a particular number for ANY star and for ANY location on earth, ask him/her to consider the North Star, which appears never to move, while all the other stars rotate around it.

Answer 3

Due to the diurnal (daily) motion, (earth’s rotation about its axis) all celestial bodies take part simultaneously in the diurnal motion.

The celestial sphere appears differently when viewed from different position of the earth.

The pole star viewed by the people in the northern hemisphere has no rise or fall. It is fixed.

Therefore your question is vague.

If you specify a particular star for example sirus, one can answer the question.

Apart from the daily rotation of earth, Sun moon planets have their own independent motion.

The earth rotates about the sun once in 365.26 days.

This we call one year.

That is the sun will be seen near a particular star once in 365.25 days.

The moon has approximately 30 days.

Therefore the moon will be seen near a particular star once in 30 days approximately.


For people on either side of the equator, the stars which are seen on either side of the ecliptic, take 12 months approximately to come to that same position,with respect to the sun.
That is 360 degree for 12 months.

In one month approximately 30 degree they will shift.

Answer 4

It depends on the time of year. The inclination will increase after the summer solstice, but will decrease after the winter solstice. The apparent path over time will be sinusoidal.

Answer 5

everyday, it will appear 4degrees higher at same time.
so after 30 days, 120 degress higher
