Encyclopedic overview
NGC 6210, sometimes also known as the Turtle Nebula or simply the Turtle, is a planetary nebula located approximately 5.4 ± 1.3 kly from the Sun in the constellation of Hercules. It is a bright nebula. It is positioned about 38° above the galactic plane at a vertical distance of about 3.3 kilolight-years (1 kpc), this is unusually high for a nebula. Due to its position, it has little extinction from intervening interstellar dust.
The nebula formed as a result of material being shed from a low mass progenitor star less massive than the Sun (~0.9 M☉) the complex structure and appearance of NGC 6210 has lead to proposals that the nebula was shaped by mass transfer in a triple star system.
