Reply to comment by Bioslug in Every planet in the solar system visible in rare "planet parade" by scot816

You're mistaken. Yes the last one was also this year, but the next one isn't for another decade. They are quite rare.

The one earlier this year didn’t include Neptune or Uranus (which the author neglected to mention). Still counts as a “parade”, but 8 together is super uncommon. The next 8-parade (see my other comment) is in 2040 and the one after that is 800 years later.

It does take time for Jupiter and Saturn to line up

Let's say every decade; so that would have happened rougly 450.000.000 times in the earths lifespan. Wouldn't call that a rare occurence

Idk man, if you go to the movies once a decade wouldn't you say you go rarely?

Different time scales. A decade for me is like a millisecond for the solar system in terms of lifespan.

Yeah but it’s rare to us which is who the information is being conveyed to. The earth doesn’t plan to read the article, nor does it give a shit.

Okay but most people in here are humans, not solar systems.

But, we aren’t known for having solar system lifespans. So, rare, indeed, for humans.

Your algebra is very impressive but your ability to understand basic conversational quantities is lacking.

After 2040 it’ll be 800 years before it happens again.
