• Multiple solar system bodies have complex photochemical hazes which derive from their nitrogen and carbon-rich atmospheres. • We generate and measure the properties of analogue hazes ("tholin") specific to Triton-like composition and temperature. • Despite other similarities, Triton tholin are much more strongly oxygenated and slightly more nitrogenated than Titan and Pluto tholin.
