With Venus we be a twin planet.
With Uranus Neptune Jupiter or Saturn... Earth would be their moon

thanks for posting
But, but...where would Alice go?
That’s what inspired my post.
“But, but...where would Alice go?”
To de oder moon!
“I don’t think that anyone really says that the associated planets don’t orbit the star because the associated barycenter isn’t colocated with the star’s center of mass.”
When you are talking about a binary star system where the two stars are nearly equal in mass, the barycenter is going to be located in the middle of space between them and not within the mass of either, so it is hardly accurate to describe Star A as orbiting around Star B or vice versa. The reality is that they are indeed orbiting around their common barycenter in space. Likewise for twin planets of equal mass, they too will orbit around a common barycenter located well beyond any atmospheres they may have. While most of these natural satellites are typically going to be mismatched in mass to the point the barycenter will be located within one of the two masses, it is useful to remember they are really orbiting around the barycenter, which can influence many of the diurnal and nutation characteristics of the primary mass where the barycenter may be found.
Tis true, but I wasn’t referring to objects of equal mass as planets generally aren’t as massive as the star around which they orbit.
Extra to APoD.
Whoops! Thanks KoRn. I have too many tabs open and I'm nodding off at the keyboard.
BTTT
How many times have I warned you that Dilaudid and FR don't go well together. 'Bad' things can happen! lol
In my younger years, there WERE some occasions where I'd go back on FR to see what I'd said the night before LOL
Wow. Jupiter light would be very bright, giving us almost no darkness and Saturn would be spectacular in the night sky. I vote Saturn, the heck with the tides. :)).
