NGC 4666 is a starburst spiral galaxy (SABc) seen near edge-on, located about 55 million light-years away in the constellation Virgo.
It has an apparent size of 4.2′ × 1.3′ and spans roughly 75,000 light-years across.
This galaxy is undergoing an unusually high rate of star formation, classifying it as a starburst galaxy. The intense stellar activity drives a galactic superwind, a large-scale outflow of hot gas escaping from the disk into intergalactic space.
This phenomenon is likely fueled by interactions with nearby galaxies, including NGC 4632 and NGC 4668, which are part of the same small galaxy group.
