NGC 6565 (also known as ESO 456-70) is a planetary nebula located 14,000 light-years away from earth in the Sagittarius constellation. It is about 13th magnitude and has a diameter of 8 to 10 arcseconds. NGC 6565 formed when a star ejected its outer layers during the late stages of its evolution. The planetary nebula is expected to remain visible to the human eye for about 10,000 years but the white dwarf will cool down dramatically, diminishing the light and heat of the nebula and making it no longer visible to the eye.[2]
NGC 6565 as cataloged in the New General Catalog (NGC) by John Louis Emil Dreyer in 1888. The object is heading towards the direction of the sun at -0,004.90 kilometers a second.[3]
