Hunting a black hole

Hi all,

I've decided to hunt a black hole in HIP 34707 the hard way, with a basic discovery scanner. I've managed to find a couple of planets using it but I'm a little confused as to where the BH should be, can someone point me in the right direction? Although it's on the system map as unexplored it's not showing up in my navigation.

Here is what the system map looks like...

Would it be in the middle of the orbits of the two planets? I've looked there but can't find anything and I would have thought it would have been found using my scanner anyway.

Thanks in advance!

The dwarf star and the gas giant are orbiting each other, so they are not necessarily close to the black hole, they are however orbiting the black hole (together as a unit) so it should be in the center of that orbit.

Have a look along the orbit line of the Main star... it, and the black hole, should be orbiting each other. It could be anything up to 500,000 LS or further though. The basic disco scanner is only effective up to a range of 500 LS.
The BH won't be in the middle of the other two bodies as, according to the system map, those two bodies (A dwarf star and a gas giant) are in fact orbiting the black hole itself. If you can find the dwarf star or the gas giant you might be able to home in on the black hole. :)

If I fly far enough away from the dwarf star and the gas giant will I see their orbit line in relation to the BH?

Get yourself next to the main star, go into the galaxy map and select the system you are in.
This should place a navigation marker right in the middle of the system. If you fly directly from the main star and passed the nav marker you will get to the black hole.

I found the dwarf star and the gas giant, they're about 50,000LS away from the main star. I tried looking in the middle of their orbits but it seems that was the wrong thing to do. So you'd recommend flying along the orbit line of the main star, that's where the black hole will be? Or will it be on a separate orbit line further out/in?

I think the Star and the Black hole are orbiting around each other.
Since the black hole is probably much more massive it's in the center of the sun's orbit. Check the sun's orbit lines.


I don't know if I'm wrong, but aren't these the only two possibilities?
Hole much more massive = center
Hole and Sun equal mass = same orbit line but opposite?

Shucks, wait - I'll try to look it up for you if I'm not too far away.

They'll both be orbiting the same center of mass of the system. As specialsymbol says, it depends on their relative mass whether the BH will be inside, outside or on the orbit line of the main star. It will definitely be on the same plane, though, so you can eliminate most of the sky from the search. It's fairly likely that it will be within a few degrees of a line that runs from the main star to the rest of the visible bodies.

And they'll always be opposite in regards to said center. Everything else wouldn't work.

So if the marker trick works it's easy.

Just go from the star to the marker and then beyond. Eventually you'll hit the black hole. The only problem I see is that it will be really, really small... at least that's what I expect, have never seen one. So you'll need to be quite accurate.

Thanks for the tip, I've done exactly as you say but can't find the BH anywhere beyond the centre of the system. Would it be the same distance as main star > centre? All there is beyond the navigation marker is the dwarf star + gas giant.

Yeah, the BH and the main star will be on the same plain so that will narrow it down a bit. The two objects will be orbiting each other (but not necessarily on the same plain as the HIP 34707 A & B) but you'll have no idea how close. You could probably roughly work it out using their respective mass.

Anyway, here's a rough schematic of your system and roughly were to try and look (labeled A in the schematic).

Good luck Commander :)

Fantastic, thanks very much for that, massive help! :)

Flew up from the system's plane, to get a feel for the main star's orbit line. Will keep hunting...

They really need to add barycenters to the game. It's so annoying not knowing the collective orbits of binary planets and stars.

Is the centre nav point of a star system supposed to drastically slow you down as you get close to it? Because that's the only thing of note I've found so far searching the space between the main star and the dwarf star

I think it was because I had the centre of the system targeted and so my engines slow down on approach.

Spent a few hours hunting it last night with no luck. So this morning I was looking for clues on Youtube, and found the perfect video: finding the black hole in HIP 34707. Sadly they had an advanced scanner so I only watched the first few seconds so as not to spoil it's exact location. I did note though that it was 54k LS away which is much further out than I assumed. The only thing I can think of is the system is laid out like this, with the main star and the BH orbiting each other somehow. I'll get back to hunting late tonight :)

See, the thing about space, is... it's black.
And the thing about black holes... they're basic premise if you will... is they're black...
