The numerous shells of material ejected from the dying star form a superposition of structures with different degrees of symmetry that give NGC 6210 its strange shape. The numerous shells of material ejected from the dying star form a superposition of structures with different degrees of symmetry that give NGC 6210 its strange shape. Abstract The spectra of the planetary nebula NGC 6210 are reanalysed using mid-infrared spectral measurements made with the Spitzer Space Telescope and the Infrared Space Observatory. The following image is of NGC 6210 from the Digitised Sky Survey 2 (DSS2 – see imprint), taken in the red channel.
It is located about 38° above the Galactic plane at a vertical distance of about 3.3 kilolight years and therefore has a low extinction.
