Starship Asterisk*

What is really fascinating is : how do we know what is going on so far away, and what does that imply about how the system formed? There are so many double star systems. A K star is not as bright as the sun, but would it have permitted a dust cloud big enough to condense a super sized Jupiter so close as to orbit in 18 hours?

Ja natuerlich. 280 light years ist 9.4608 x 10^12 kilometer. Bitteschoen. (Can’t do umlauts on the laptop.)

That's what I was wondering. If the planet was rocky, I suppose the temp would be similar to it's present state, except that it would take longer to go from sun-side to dark-side? But that is I guess a moot point since both bodies have been there a long time? The other thought tho is perhaps cold space on the dark-side has less effect on a gaseous body constantly getting quick heat osmosis than a rocky body does? Mercury's rotation is so slow, and it's colder side is very cold, possibly having permanent ice at the poles (or one of them).

And won’t we quickly run out of Earthly nomenclature to name objects elsewhere? There is also some hubris in our assuming it falls to us to name everything. I doubt the Wasp-43 system has its own intelligent life with naming rights, but maybe there is elsewhere. Some day these aliens may pop up and say ”You named our planets what?!”
