Existence of a celestial body big enough for early civilization to be thought of as a second moon












5












$begingroup$


Is there a possible scenario in which once a year a celestial body can be seen from the surface of the Earth-like planet for a short period of time?




  • With it being big enough for early civilization to consider it a second moon but much smaller than the actual one.

  • And occurring each year for one thousand years.


I thought two moons questions are similar enough, but I haven't found a proper answer for myself.



Thank you!

Do you mean the moon is in the sky, visible and basically the same size, for a 1,000 year period, or that the inhabitants see it once every 1,000 years, like a comet?

    @JBH thank you :) No, no, I want it to be much smaller to lessen the impact on the system. But what I mean is the ideal scenario for it to be visible once a year, each year, for 1,000 years.

Yes. That would be a kind of quasi-satellite.



And Earth already has a small one - it's called Cruithne. At perigee, a larger Cruithne might well be visible, always in the same section of the sky.



enter image description here



A larger body would be less stable, but if you only need one thousand years, I think it could work out.

    A comet could fill this role. Comets are notoriously bright.



    comet
    https://en.wikipedia.org/wiki/File:Comet_P1_McNaught02_-_23-01-07.jpg



    I like the tail but you could have your celestial body be made of something more solid, equally reflective, but not falling apart and leaving the tail.



    Comets also have very elliptical orbits and visit infrequently. In this list of periodic comets, 3200 Phaeton has a period of 1.4 years - very short by comet standards.

    3200 phaeton orbit



    So: your second moon is a very bright short period comet. That seems plausible.
