nebula located around 3,000 light-years away in the
constellation Cygnus. It was discovered in 1878 by Edouard

Observatory. It is one of the smallest planetary nebulae,
measuring only 0.2 by 0.1 light-years whereas the typical size
for a planetary nebula is 1 light-year. NGC 7027 is one of the
visually brightest planetary nebulae. It is about 600 years old.
