That is literally the exact thing that I thought too. Its interesting that a sentence like this can be so easily misinterpreted by multiple people in the same way.

Isn't it the capitalization of the first characters of each word which causes the confusion? New evidence that all stars are born in pairs versus New Evidence That All Stars Are Born in Pairs I've never understood the rationale of capitalizing headlines this way anyway (is it the American way?)

Yes, titles of things (including but not limited to visual art, written works, songs) are generally all capitalized except for small words

I read that as Paris. On the plus side it makes more sense now. Should probably go to sleep...

I also read Paris, and thought "stars" referred to celebrities. Oops

I also read it as Paris, but correctly interpreted "stars" as celestial. It was a very confusing two seconds.

> Many stars have companions Most stars. Many years ago, i downloaded a copy of the Gliese star catalogue, and set about generating some star charts of nearby space in VRML (which should give you some idea of just how many years ago that was). Multiple stars are listed as multiple entries in the catalogue, and i realised that if i drew markers for each one, they'd overlap and look terrible. Never mind, i thought, the…

oh wow .. VRML. That does take me back

Well what do you know, Jupiter doesn't actually orbit the sun! Not properly anyway http://www.iflscience.com/space/forget-wha-you-heard-jupiter...

This is silly semantics. Jupiter and the Sun both orbit the center of mass of the Jupiter-Sun system. The article is making the point that for Jupiter and the Sun this point happens to be just outside the surface of the Sun. It's much simpler to say "Jupiter orbits the Sun" than "Jupiter and the Sun both orbit the center of mass of the Jupiter-Sun system". You can think of the former as a shorthand for the latter.

That's true of all planets no? The Earth and sun orbit the center of mass of the Earth-sun system.

Not impossible, but rather unlikely. According to TFA, the partner star was much further out. Also, gas giant planets Jupiter's size are fairly common I thought (this knowledge may be outdated).

TFA? I'm getting "The Force Awakens". Or "Teach For America".

I read it as The Feature Article, which looks dumber written out than it did in my head. You know, like Feature Presentation.

If all stars are born in pairs where is our suns sister sun and earths sibling planet?

From the article: Based on this model, the Sun's sibling most likely escaped and mixed with all the other stars in our region of the Milky Way galaxy, never to be seen again.

is it possible that it's just on an extreme orbit and we may one day reconnect?
