Austin Venus does noit have an apparent motion,neither does Mercury,Mars Jupiter or any of the other planets. So they don't appear to move? They just stay stationary in the sky? Austin The orbital motions of Mercury,Venus ,Mars and the other planets are seen to move against the stellar background over long periods. So they do appear to move ("apparent motion")? "Seen to" and "apparent" are synonymous terms, oriel. Someone with your command of language ought to know that. Make up your mind. Either they do appear to move, or they don't. Austin- Hide quoted text - - Show quoted text - True and apparent motions are just common astronomical terms,the movement Pete's shadow is not due to the apparent motion of Venus but the true motion of the Earth,specifically axial rotation. I am sure Pete and Anthony will be doing cartwheels of joy looking at your brilliant defence but they have at least the comfort of knowing that they are no better or wrorse than your level of understanding.I welcome your attempt as it always is an occasion to present the difference between apparent motions and true motions. The apparent motions of the planets,for both Ptolemaic and heliocentric astronomers ,were both the same - http://antwrp.gsfc.nasa.gov/apod/ima...loop_tezel.jpg The heliocentric astronomers however used orbital comparisons between the Earth's orbital motion and the other planets to conclude a common heliocentric orbital motion - http://antwrp.gsfc.nasa.gov/apod/ima...2000_tezel.gif There is no such thing as 'apparent' motion of Venus against an axially rotating Earth unless you really want to highlight that Pete here is an unapologetic astrologer.I am sure he has recognised that by now but due to your spirited defence I get to really shopw the guy just how stupid he is. |
