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

+0
−0

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!
