A triple neutron star system orbiting a primary black hole (quaternary system in total). There is a close pair of neutron stars, orbiting about 3 light seconds apart, which can be flown through like "goal posts", whilst a third, smaller neutron star orbits both with an inclined axis of rotation. Interestingly, the two closely-paired neutron stars cause gravitational lensing around themselves, like a black hole, which can clearly be seen when travelling at speed within a few thousand light seconds of them. A possible tourist destination, but also valuable to any thrill-seekers who want the "buzz" of flying through the middle of a group of close neutron stars.
