The bright O-type star HD 175876 has a companion neutron-star with a surprising feature: Extremely large rings. The effective radius of the rings are 12 light seconds, and it has a mass of 5.16 x 10^17 kg - slightly greater than Thebe, a small moon of Jupiter. As the neutron star has a radius on the order of 10km, this object has an exceptionally large ring size relative to the central body.
