    Default Suns Rotation Along the Ecliptica



    Hi!

    In what direction is the sun rotating along the ecliptica (on the northern hemisphere if relevant) and why? Clockwise or counter clockwise?

    If you look at the equator of the sun from the northern hemisphere it rotates from left to right (or toward west).
    It is easy to know if you observe how sunspots change their location over a period of several days

    I understand what you write. To clarify, my question is not about the rotation of the sun along its own axis. My question is about the suns path along the ecliptica.

    When I check out the Right Ascension position of the Sun as function of time I find that the RA increases. I interpret this as the Sun is moving in a clockwise direction along the ecliptica. Have I interpreted things correctly?

    The suns path is EASTWARD along the ecliptic (as seen to you on earth). RA is simply the angle from the vernal equinox toward east, so if it increased the object is moving east.

    I believe this discussion was on the Beginners Forum and I am a beginner. When joining Astronomyforum I was informed that there were no dumb/unaswarable questions. I am surprised that the moderator wrote that "We Dont Answer Homework Questions". My question is not a homework question and that is why I continue the discussion. And please explain. This is Beginners Forum and not a forum for Pros astronomers as far as I understand. The question might be a simple one but anyhow. If I am wrong please enlighten me.

    Please explain the suns motion on the celestial sphere along the ecliptica! Is it clockwise or counterclockwise? If the sun moves in the eastern direction then I interpret things that the sun moves in the counter clockwise direction as seen on the celestial sphere. Is this correct?

    And of course I have checked out on the ecliptica on Wiki and on the Internet!

    I think this was a test question? Had to get the planet models out and watch what they do. Now my only question is ??? did the models i buy rotate correctly or was it a toy??? hahaha,,,,, Ok, Seriously I live in California and am thinking about driving up to Oregon to see this one and capture it on imagery. Anyone in the Sacramento area thinking the same and is there anyone in the eclipse area have a recommended area to go to where it is not super crowded? Let me know, this one sounds fun....

    If you think about it , the Sun appears to move from left to right relative to the Earth - northern hemisphere clockwise . But of course the Sun's stationary (*) and it's the Earth ( & planets ) that move .

    (*) Of course it's not ! The Sun is influenced by the Planets - and wobbles , whilst moving on its own orbit within our Galaxy which in itself is moving .
