Y9u guys suck at Astro why cant u anwser these questions???

Question

Now, I got your attention
How many hours is it from sunrise to the next sunrise on Venus???

If you looked directly north on venus in the nightsky would you see the stars spinning CCW around polaris??? If not what would you see and why???

Imagine Earth stoped orbiting the sun, (stayed in the place that it was). how would this change our solor system model affect the apparent motion of the stars in the night sky on a day to day basis???

Imaging Earth stopped orbiting the sun, how would this change the apparent motion of the stars in the night sky on an hourly basis???(lookin at the stars continusly through the night)

Answer 1

ok...i think you suck for not being able to do your homework yourself.

Answer 2

I'm not answering it either.

Your questions are all loaded in some way or another. First of all, Venus may not point at Polaris, I don't know what it's tilt is, but I don't think it is 23.5 degrees like Earth, much less facing the same direction...

Secondly, with all the clouds on Venus, you wouldn't see star spinning at all because you wouldn't be able to see them at all.

It's not the orbit that really effects the apparent motion of the stars, it's the rotation of the Earth on it's axis. Yes, the motion is affected slightly, but none that you would notice in a night or two...this will be true for a day to day basis and an hourly basis.

Answer 3

As I wrote in response to the other place where you asked this question, you can calculate the time between Venerian sunrises (assuming that you could see the sun at all from the surface of the planet) as follows. Two motions affect the time between sunrises. First is the rotation of Venus about its axis, and second is the revolution of Venus about the sun. Venus orbits the sun every 224 earth days, so in one earth day its revolution (taken by itself) causes the sun to move through the sky by 360/224 degrees from west to east.(retrograde) each earth day.

Then take into account Venus's rotation about its axis. Its sidereal period of rotation is 243 days, in a retrograde direction so its rotation, taken by itself, causes the sun to move from west to east 360/243 degrees per day.

I will leave to you the exercise of adding 360/243 and 360/224 to get the total daily motion of the sun through the Venerian sky. When you get that number (call it X) divide 360 degrees by X degrees per [earth] day to get the number of earth days between successive sunrises on Venus. Then multiply that number by 24 to get the number of hours between successive sunrises

You would not see the stars spinning around Polaris (if you could see the stars at all, which you can't) because the axis of Venus doesn't point to Polaris. It points (very roughly) in a direction that, compared to the direction of Polaris at midnight on June 21 as seen from Earth, is 23 degrees down toward the horizon.

Answer 4

Because I suck at astro, that's why I can't answer your questions, why do you ask such rhetoric?
