NGC 4457

NGC 4457 is a barred spiral galaxy located approximately 55 million light-years away in the constellation Coma Berenices. It is a member of the Virgo Cluster, a large cluster of galaxies that includes Messier 87 (M87) and Messier 49 (M49).

Characteristics:

NGC 4457 is classified as an SBab galaxy, indicating that it is a spiral galaxy with a prominent central bar and relatively tightly wound spiral arms. It is notable for its well-defined spiral structure, showcasing active star formation regions within its arms, visible as bright blue patches.

Discovery:

The galaxy was discovered on April 12, 1784, by the German-British astronomer William Herschel.

Observational Data:

• Right Ascension: 12h 28m 59.0s
• Declination: +03° 35′ 59″
• Apparent Magnitude: ~11.0

Significance:

As a member of the Virgo Cluster, NGC 4457 plays a role in understanding the dynamics and evolution of galaxies within dense environments. Studies of its star formation rate and distribution of elements contribute to our broader understanding of galactic evolution. Its proximity allows astronomers to study it in detail and compare it to other spiral galaxies in different environments.
