Q&A

Can there be a unique planet visible each different month?

+0
−0

In my world, ten is an important number that shows up frequently. In the solar system my world belongs to, there are ten other planets beside it, and there are ten months in a year.

I know next to nothing about astronomy, but I wondered if it were possible to have people on my planet be able to see in each consecutive month a different planet and recognize it as a planet*, maybe because the planets are brighter with clear shapes rather than points of light, or maybe because the planets' orbits take them close enough to my planet that they can be recognized.

My world is similar to Earth in size and proximity to the sun, which is comparable to our sun. The sizes of the other planets are mutable.

Is it possible that every month a different planet could be identified as a planet without a telescope?

*My world has medieval-era technology, so there are no telescopes.
