Just your regular resonant planetary system...Nothing to see here...Call me back when you find one where they orbit the star with periods that are a sequence of prime numbers.... "Resonance in the planetary system HD 110067" - https://www.dlr.de/en/latest/news/2023/04/six-planets-in-res...

Or one with three planet sharing the same orbit, perfectly spaced!

Or a planet with 13 moons evenly-spaced on the same orbit? C.f. Ilus IV / New Terra in The Expanse.

What is the "mathematically perfect" aspect of this system? I don't see it in the article.

The caption for the picture says this:

> The six planets orbit their central star HD 110067 in a harmonic rhythm with planets aligning every few orbits.

Are we more likely to find alien tech in a "mathematically perfect" star system? Why? The article doesn't mention it.

They might not be planets but planet-sized, artificially-created cities/machinery/engineered objects. Think about it: If you were tasked with creating a planet-sized thing why would you give it anything less than a perfect orbit? You'd also put it in orbit around a super stable dwarf star to maximize the useful life of the project.

Even if they are planets, imperfect orbits lead to problems in the looooooong term. An alien civilization may forcibly alter the orbits of the planets in their solar system in order to stabilize it. E.g. before turning their star into an engine that moves everything along with it across the universe (e.g. out of the way of an incoming problem like a black hole or to prevent an astronomical collision).

If we're going to look into every resonant system shouldn't we start with the moons of Jupiter?

Are we not looking already?

Makes me think of how the Puppeteers in Niven's Known Space escaped the explosion at the center of the galaxy by moving 5 planets in this configuration

with an inertialess drive that (I think) they bought from the Outsiders.

Not convinced until they find a Dyson sphere...

Or one where vertically aligning planets is easy with CSS

They offer no hint why transiting the star could help us pick up radio transmissions. If they mean the planet going behind the star (being "occulted") would cut off the radio signal while it is back there, they should say that instead.

The piece seemed a bit wooly to me. This bit caused a little twinge of pain:

Signals from such a transmitter placed on a planet spinning around a foreign star would drift in time when observed from Earth, "the same as when an ambulance goes past you, the sound of it shifts from very high to very low"

What's wrong with saying Doppler, frequency, or pitch maybe?

I’m not sure I want to meet the alien species that can arrange a star system into a prime sequence.

Earlier quoted context omitted.

Or a planet with 13 moons evenly-spaced on the same orbit? C.f. Ilus IV / New Terra in The Expanse .

I just wonder so, if there are multiple planets in equal distance between them, would we be able to tell the difference between three planets and one on a fast orbit?
