NGC 691 is a Spiral Galaxy located in the constellation of Aries in the northern hemisphere. NGC 691's distance from Earth is 119,004,677.53 light years. NGC 691 is called NGC 691 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.

2020年2月24日 · This Hubble image shows NGC 691, a spiral galaxy located 125 million light-years away in the constellation Aries. The image is made up of observations from Hubble’s WFC3 instrument in the infrared and optical parts of the spectrum.

NGC 691 is a Spiral Galaxy in the Aries constellation. NGC 691 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 13.5, NGC 691 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.
