In my experience of exploration, that is fairly rare, but there are rarer things in the galaxy
Nice pic by the way
Not rare at all. Uncommon, sure, but once you've been out for a few weeks you'll likely see a few a day at least.
Yeah I thought as much, reading the cartography records there's some amazing stuff out there. Well still, it was a nice sight!
They're nice until you enter a system right next to one and wonder why you are instantly fuel scooping.
Just be wary that this can happen for all types of stellar bodies, neutron stars, black holes and white dwarfs included...
There will also be times where you enter the system "through" the second star, which we all call a "brown pants" moment...
My worst was entering a 0.1d orbital binary where the main was an O class and the secondary was a herbig ae/be that was thrown right in my face due to the close proximity. I narrowly escaped death!
Producing your own brown dwarf so to speak
The real fun with those binaries is when the route of your exit from hyperspace takes you through the smaller one as you approach the biggun. If they are a fair way apart it will just give you a huge shock and a rush of adrenaline. If they are too close together, you will arrive overheating with Verity screaming at you, and have to take immediate action.
