  •   Earth's Orbit Path & Variations#9946

    Dear Karthikeyan KC,

    Many thanks for your detailed and considered reply.

    However, these are the facts I already know.
    My question was where do I find the data that tells us the actual positions of the earth during its varying orbits.

    The earth’s position relative to the sun changes constantly, I rather assumed that these changes are measured and recorded.
    It may be, however, that the earth’s wobbles month by month and year by year are too slight to be measured.

    If you know about such data, I would be very grateful if you or the Geek Swipe Team were able to enlighten me.

    All the best,

    Many thanks, this is what I was looking for.

    SPICE didn’t show up in search results but then, I didn’t know the term, “astronomical ephemeris”.

    I’ll hopefully find something that is at least approximate, that would be enough.
