just think if citys at the 50th,40th or even 30th parralel could have 24 hrs day in summer and 24hrs night in winter it would problaly cause a lot of anxiety and seasonal affective disorder in winter would skyrocket!!

OK, so what is your point of this post in Ask the Astronomer?<br /><br />Has anyone suggested such a thing? No<br />Is it possible? No<br />Please show me wrong if I am.<br />So why did you post it here?<br />Perhaps you should post it in Human Biology? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

for constant daylight at 50 the earth wil be tilted 40degrees for 40 the earth tilted to 50 degrees and for 30 the earth is tilted to 60 degrees.with precession or planetary wobble it could br possible

That is not correct. No matter what the angle of axis, during a solar orbit, seasons occur.<br /><br />You think that the angle is relative to the sun, but that is not right. The axis of rotation is not aimed toward the sun, but rather at a point in the sky. During a solar year, that spot will point toward the sun and away from the sun. Hence, seasons. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

in summer it it is tilted towards the sun .the 23.45 parallel is aimed diectly at the sun at noon on jun 21 that why the sun is overhead there .if we had a more extreme tilt the axis would not point at polaris anymore

It is not aimed directly at the sun on the solstice. Rather it is aimed at a point 66.5 degrees above the sun.<br /><br />If it were aimed directly at the sun, the entire southern hemisphere would have no sunlight at all on that day. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<font color="yellow"><br />in summer it it is tilted towards the sun .</font><br /><br />Ahem, in summer, the earth's axis is still pointed at Polaris. <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
