Kepler-90 planetary system explained

Kepler-90 is a Sun-like star 2545 light years away from Earth and is the first planetary system to tie with the Solar System in number of planets. Andrew Vanderburg, astronomer and NASA Sagan Postdoctoral Fellow at The University of Texas, Austin, explains the Kepler-90 planetary system.

I wonder if aliens on those planets are like “what’s you Kepler 90C sign?”

[equalssign]

A: take Sol's status as an 8-planet system away.
B: this system now technically has 9 planets
C: the effect of these two changes is that no known system has 8 planets, thus far.

Not sure if this is the right place to ask this.
Since the planets are so close together is it possible for any of the planets to have moons?
if the Gas giants have moons would they be in the habitat zone?

Can any body tell me the semimajor axis of Kepler 90i in terms of AU? I found this to be 0.2 but that gives an orbital period of 31 days! The original paper didn't show this unfortunately!

[MegaAgill]

Not to scale? Wait, you mean in real life Saturns rings don’t actually touch Jupiter?

[VortexBricks]

Why do I always see Jupiter upside down

[arbab]

Is there any physical rule that limits the number of planets around a given star?

[clarkabeast]

Why is almost all the planets in the K90’s are gas giants

[abloogywoogywoo]

The question must be asked: Are all exosolar systems unique?
And, if so, is this good or bad for life on other worlds?

[dicerosautismambient]

Planets like kepler-90i may be habitable. The night side if the planet is tidally lock may have life.

thanks for choosing Kepler Airlines, have a nice flight.

[arcangle]

They should build small satellites with ion thrust to reach lightspeed and build in camras an a drone to look closer on and above the planet for lifeforms also for earth like planets

[scarlettbegonia]

Are they gonna keep it a planet, or are theu gonna kick the little guy out like we did with Pluto lol??

[Flesh_Wizard]

This system looks like it was compressed lol

[islamiclecturesdatabase]

wait.. u're talking about planets? using a walkie talkie? DUDE.. GET A MIC FOR A DOLLAR!
