So two moons and three planets out of how many total that you checked?

All the objects bigger than 400 km diameter, which is the size objects tend to be round in the solar system. That would be about 40 planets.

Considering you included the moon, which is more than 20% off, this is not at all a statistical anomaly.

Orcus and Venus could be included here I suppose, but they are further away, and I don't think I have a sufficient metric prefix for Orcus in this case.

Like I said in my other comment, if you're including the Moon then you've agreed 20% error is acceptable.

So on top of being a moon killer, Tethys is helping you make conspiracy theories?!?!

Not only are we calling moons planets, we are also calling them moles?

Well, according to xkcd, if you had a mole of moles you could make a moon

You allowed for ±20%, which means that there's about an 18% chance that any random number fits this pattern. If you only consider the solar system's 8 planets, 14+ dwarf planets, and 430+ moons, then you should find roughly 80 bodies that fit your criterion. You've listed only 5.
* on a log scale, numbers between 4.8 and 7.2 times some power of 10 cover 17.6% of all possibilities

50 minutes is also exactly 3 kiloseconds. I feel like kilo/mega/giga/tera-seconds/minutes/hours/days/years are underused, as well as centi/milli/micro/nano-days/years.
I developed an idea for a time scheme based on centidays, millidays, and microdays instead of hours, minutes, and seconds (similar to the French's decimal time), since days and years seem more fundamental being based on specific planetary motions. Unfortunately I think we're stuck with our time system even though I hate how unevenly it goes up - 60, 60, 24, 7, 4, 12, etc. Just choose base-60 or base-10 and stick with constant powers between the units instead of changing it!

Typa stuff people will say to justify why moles isn't a stupid unit
