I would like to know what people think they are doing by ignoring the structure which assigns 365 1/4 rotations to a complete orbital circumference or adopt a completely nonsensical 366 1/4 rotations for the same period ?.Did our ancestors do something so chronically bad that we decide to vandalize their system so you can go outside and imagine that the Earth has 366 1/4 rotations every year ?. If your heart does not break for what they did in the late 17th century to the great astronomical insights then you must have a heart of stone and a brain to match.Why would NASA sanction such cruelty when the citizens its represent expect the highest standards,not the lowest possible ones ?.Maybe you can answer that question because I cannot. |

The 366-1/4 rotations are with respect to the fixed stars... ... Maybe you can answer that question because I cannot... Well, that's the whole problem here... of course you can answer that question. You have always been able to answer that question, but you choose not to, because... well, I don't exactly know why, but I'll guess that it is because you like being a Troll who draws attention to himself more than you like to actually contribute anything positive. I know it and you know it... and many others here certainly suspect the same thing. It is probably time for you to move along to another group that does not know you... yet... it may be that your whole purpose in life is simply to serve as a warning to others. Others have implied that you suffer from insanity... but I personally think that you enjoy every moment of it. \Paul A |

Yup--Same thing from the ESA, and that is because it is correct, Gerald! Even amateur astronomers can easily measure one rotation of the earth. Vega is well placed to make the measurement.

If you insist that the Earth rotates 360 degrees in 'sidereal time',you are explicitly stating there are 366 1/4 rotations corresponding to an orbital circumference and that is plainly impossible.This is not about indignation Sam but rather a hopeful message,it is almost something that I would not rather think about for any longer than is necessary yet this issue of competence does exist and needs a very resolute steering mechanism to push 'sidereal time' reasoning aside and that is where the contemporary institutions have to act with a decisiveness that is long overdue.If NASA , ESA or any other institution and organization involved in investigating the terrestrial and celestial continue to defy common sense by now confidently stating that there are 365 1/4 daily cycles corresponding to a complete orbital circuit and period then everything else is pointless,that they actually do state 366 1/4 rotations must strike some readers as horrific. I most certainly thank you for being dignified,even if I disagree with your position it is a pleasure dealing with another person who takes a clear position and even should you never alter your position,you have my gratitude. |

Putting that in context,the world's astronomical institutions or as individuals calling themselves astronomers express that there are 366 1/4 rotations of the Earth in one orbital cycle when they already know that they will experience 365 daylight/darkness cycles in a year from January 1st to December 31st with an additional 366 cycles every 4th year corresponding to 4 complete orbital circuits made up of 365 1/4 rotations.Even in this information saturated era,the loss of this basic experience to 'sidereal time' reasoning simply defies basic common sense and I would much prefer to be optimistic that intelligent people would choose to consider what the leap day correction represents in terms of both daily and orbital motions than be indignant over the incompetence of those late 17th century people. It is not a matter of considering your position to be false Sam,it is just that I do not know how people can do something as drastic and dismal as ignoring their experience of the daily daylight/darkness cycles and this is what happens with a 'sidereal time' ideology based around 366 1/4 rotations. |

Speaking **just** for me I rarely read what you write. I am quite certain in my own mind what winding up people through simulated stupidity is your hobby. BTW there is nothing wrong with having a hobby and provided readers on usenet appreciate what floats your boat all well and good. It was mildly amusing for the first few weeks but almost everybody has sussed you out now so it might be time for you to move on? In any event choose one of you real life friends and ask them to read the material you post to this group. Specifically ask them if most of what you write makes any kind of sense. I'm suggesting you ask a friend because you clearly don't accept the opinions of the people on this list - many of whom have shown the patience of a saint in trying to explain basic astronomical science to you. |

The Earth's orbital speed is,on average, 6 times that of equatorial speed so that trying to express orbital distance traveled using daily rotation to natural noon in 24 hours or a 3 minute 56 minute difference to 'sidereal time' is just pure vandalism. |

That's what the siderial day is referenced against. |
