NGC 3833 is a barred spiral galaxy located in the constellation Virgo, about 280 million light-years from Earth. Discovered by astronomer William Herschel on April 15, 1784, NGC 3833 has a Hubble classification of "Sc," indicating loosely wound spiral arms and a relatively small central bulge. The galaxy spans roughly 1.4 by 0.7 arcminutes in the night sky and shines with an apparent magnitude of around 13.5, making it a faint object suitable for observation with larger telescopes.

Due to its distance and redshift (z ≈ 0.020214), NGC 3833 is part of the large Virgo Cluster of galaxies, a group containing thousands of galaxies. In various catalogs, it is also known as PGC 36441 and UGC 6692.

Characteristics

NGC 3833 is classified as a barred spiral galaxy (type Sc) within the constellation Virgo. It exhibits a loosely wound structure with a small central bulge, characteristic of its classification. The galaxy spans approximately 1.4 arcminutes in length and 0.7 arcminutes in width, making it relatively small in apparent size compared to other galaxies.

With an apparent magnitude of around 13.5, NGC 3833 is a faint object that requires moderate to large telescopes for observation. It has a surface brightness of 13.3 magnitudes per square arcminute, indicating how dim it appears against the background of the night sky. The galaxy's redshift value of 0.020214 translates to a recessional velocity of approximately 6,060 km/s, placing it roughly 280 million light-years away from Earth.
