DID ANYBODY NOW HOW NEPTUNE IS SPINNING IT IS SPINNING UP WARD DOWN

Neptune is not spinning upside down. Its axial tilt is 30 degrees, about the same as Earth.<br /><br />Uranus is tilted 98 degrees, so you could consider it to be upside down, (by just 8 degrees) <div class="Discussion_UserSignature"> <p> </p><p> </p> </div>

Actually, if it has an inclination of 98 degrees off the North/South axis (wrt the plane of the Solar System), then it's just over 1/2 way to being upside down. It's lying on it's side. <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>

I thought you said you lost weight. If a bowling ball is rolling around yourself, your gravity well is deep enough to keep it in orbit <img src="/images/icons/smile.gif" /><br /><br />Wayne Too, -15 lbs <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

I have known a few stout Lads who could clear the neighborhood orbit free of debris as well. <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>

all the bodies are spinning in right but only Neptune is spinning but it is spinning down because a halley comet had came very fast and hit the Neptune so its spinning down not like our earth it is spinning

Check the link below on Neptune, particularly its axial tilt of 28.32 degrees.<br /><br />http://en.wikipedia.org/wiki/Neptune<br /><br />Then check the link below for Uranus axial tilt which is 97.77 degrees.<br /><br />http://en.wikipedia.org/wiki/Uranus<br /><br />As mentioned by others here, it is Uranus that is tilted to such an extreme as to be considered to be on its side. A comet nucleus is nowhere near large enough to cause a planet to be tilted in such a way. It could have been struck by a KBO eons ago. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

sqizee - Thank you for inviting questions about Neptune. You have zeroed in on rotational plane and axis. <br /><br />The origin of Neptune and Uranus, plus their subsequent histories, had effects on this and other properties.<br /><br />My question to you is:<br /><br />Why is Neptune of higher mean density than Uranus?<br /><br />Why is Neptune's radiation of heat so different from Uranus? Neptune, like Saturn and Jupiter, emits about twice as much heat as it receives from the sun.<br /><br />However, as of 1991, no internal heat source, or evidence thereof, had been found on Uranus.<br /><br />This is from "The World of Science," volume 7, p. 34.<br /><br />Does this lack of an internal heat source on Uranus have some connection to its unique rotational axis?

According to recent theories of solar system development, Neptune actually formed closer to the sun than Uranus, and swapped positions due to resonances with Jupiter and Saturn. This would explain<br />it's higher density if the postulated density of the planetary disk is correct. And different combinations of elements. I'd say that's a subject for future resolution.<br /><br />On what basis are you assuming Uranus radiates less heat?<br />I do not know how much of that measurement is from fly by spacecraft, and how much is from earth based measurements, which could be biased (there's actually a pun here) by the alighnment of Uranus' pole over the part of an orbit since we've known it existed. It's only been a short time <img src="/images/icons/smile.gif" /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
