Said mrjesse: Can you find anyone at nasa who plans space missions and who agrees with you? The more I hear of your idea the more crazy it sounds.
LOL They all agree with me : )


You still haven't substantiated your claim. If all of NASA agrees with you, and if it's true, you've gotta find some mention of it online. Heh, even if it's not true you ought to find some references online. I mean, the internet covers everything that is and most of what isn't. If this is such a simple concept as you claimed there ought to be lots of websites or beginning astronomy books that talk about it.

So what do we have? Lots of websites that say your wrong, and zero that say you're right? Isn't it a time you took that into consideration? Is it really honest to say that it's such a simple concept and that all of nasa agrees with you when you can't find any articles that claim the same?

Here are some websites that say you are wrong:
Light-time correction, The Indological Knowledgebase
Actually, during its light-time, the Sun does move slightly around the barycenter (center of mass) of the solar system as a counter-balance to the massive jovian planets (Jupiter, Saturn, Uranus, and Neptune). Thus the true light-time correction of the Sun is extremely small, usually much smaller than 0.03".
That's nowheres near your 2.1 degrees.

PVAstro0702, James Bradley report
Light-time correction has absolutely no relation to the motion of the Earth with respect to the Sun.


Fundamentals of Astrodynamics and Applications By David Anthony Vallado, Wayne D. McClain, page 299
For stars, we ignore light-time correction.
Control Software for the Bochum Radio Telescope by James Miller G3RUH
It is able to calculate objects' coordinates properly, accounting for the whole litany of small corrections without regarding each as a special case and with various degrees of approximation. These are:
* Light-time correction (excepting stars)
* Gravitational deflection of light by the Sun
* Aberration due to velocity of Earth around Sun
Notice how they correct for the 20 arcseconds of Stellar Aberration but not for light-time correction of stars (the Sun is a star!) Why is this? I'm telling you that it is because like the sun, the stars are relatively motionless!

http://mysite.du.edu/~jcalvert/phys/doppler.htm#Aber
There is another reason why observed positions differ from actual ones, which is simply movement that takes place while the light is on its way. This is called the light-time correction, and is of interest for satellites and other nearby, rapidly moving, objects. For stars, it is usually neglected.


It does matter what is spinning and what is orbiting.

It's time to face the choir. This idea of yours isn't working. And it's gone past the point of innocent or honest ignorance.

If you want to believe that everything is where it appears to be then go ahead : ) I can't change your mind and I really have very little interest in changing your mind.

Good luck : )
