The nebula is about 2,000 light-years away from Earth.

It has a diameter of about 1 light-year.

M57: The Ring Nebula - May 4th, 1998.

"It looked like a ring in the sky. Hundreds of years ago astronomers noticed a nebula with a most unusual shape. Now known as M57 or NGC 6720, the gas cloud became popularly known as the Ring Nebula. It is now known to be a planetary nebula, a gas cloud emitted at the end of a Sun-like star's existence. As one of the brightest planetary nebula in the sky, the Ring Nebula can be seen with a small telescope in the constellation of Lyra. The Ring Nebula lies about 4000 light-years away, and is roughly 500 times the diameter of our Solar System. In this picture by the Hubble Space Telescope, dust filaments and globules are visible far from the central star. This helps indicate that the Ring Nebula is not spherical like one may believe it to be, but cylindrical. Perhaps the Ring Nebula would appear differently if viewed sideways."

The geometry and structure of the Ring Nebula (Messier 57), Released on May 23, 2013 [NASA, ESA, and A. Feild (STScI). Image: CC BY 4.0]

«This schematic shows the geometry and structure of the Ring Nebula (Messier 57) as viewed side-on. This shows the nebula’s wide halo, inner region, lower-density lobes of material stretching towards and away from us, and the prominent, glowing disc. We are gazing almost directly down one of the poles of this structure, and view the brightest part of this nebula as the colourful main "ring". This is composed of gas thrown off by a dying star at the centre of the nebula.» ― ESA/Hubble
