It is a small planetary nebula hidden about 3 degrees southeast of the North American Nebula in the constellation Cygnus.
The distance is estimated to be 3000 light-years, with a span of only 14 arcseconds.
Its actual size is only 0.1 to 0.2 light-years, and it is considered a very young planetary nebula, as the central star began emitting gas only 600 years ago.
In this image, it barely appears as if two regions are attached, but detailed images released by the Hubble Space Telescope reveal a complex structure resembling clover leaves.
Unusual ionization spectra, not typically seen in planetary nebulae, have been observed, making it an active subject of research in terms of stellar evolution.
