NGC 1277 is a lenticular galaxy located about 220 million light-years away in the constellation Perseus.
It is one of the most massive known galaxies, with a supermassive black hole at its center that is estimated to be about 17 billion times the mass of the Sun. The galaxy is relatively inactive, with little ongoing star formation and a low rate of supernovae.
Its mass is largely made up of older stars, which gives it a reddish color. NGC 1277 has been the subject of several studies in recent years due to its unusual properties and massive black hole.
What is the diameter of NGC 1277?
NGC 1277 is relatively small compared to other galaxies, with a diameter of only about 10,000 light-years. It is classified as a lenticular galaxy, which means it has a disk-like structure but no visible spiral arms.
Despite its small size, NGC 1277 is one of the most massive known galaxies, with a supermassive black hole at its center that is estimated to be about 17 billion times the mass of the Sun.

Who discovered NGC 1277?
NGC 1277 was discovered by the Scottish astronomer James Dunlop in 1826. Dunlop was an amateur astronomer who made several important discoveries during his career, including the galaxies NGC 1275, NGC 1278, and NGC 1291.
He also discovered several nebulae and star clusters, and was one of the first astronomers to use the term “galaxy” to describe these large collections of stars.
Dunlop’s discoveries were made using a small telescope that he built himself, and he published his findings in a number of scientific papers.
NGC 1277 and its Black Hole
NGC 1277 is known for having a supermassive black hole at its center that is estimated to have a mass of about 17 billion times that of the Sun.
This makes it one of the most massive black holes ever observed, and it has attracted attention from astronomers and the media because of its size and the unusual properties of the galaxy it resides in.
The galaxy itself is relatively small and has a low mass for its size, with a total mass estimated to be about 50 times that of the Milky Way.
This has led some researchers to suggest that the black hole at the center of NGC 1277 may have grown to such a massive size because it has been able to consume a large fraction of the galaxy’s mass over time.
The discovery of the supermassive black hole in NGC 1277 has implications for our understanding of the evolution of galaxies and their central black holes.
It suggests that black holes may play a more significant role in the evolution of their host galaxies than was previously thought.
It is known that most galaxies, including the Milky Way, have a supermassive black hole at their center.
These black holes are thought to be critical in regulating the growth and evolution of their host galaxies, as they can influence the movement and distribution of stars and gas within the galaxy.
However, the extreme size of the black hole in NGC 1277 suggests that it may have played a more significant role in the evolution of the galaxy than was previously thought.
Some researchers have suggested that the black hole may have had a direct influence on the formation and evolution of the galaxy, rather than just influencing it indirectly through its gravitational influence.
Conclusion
Overall, the discovery of the supermassive black hole in NGC 1277 has opened up new avenues of research into the role of black holes in the evolution of galaxies and the process of accretion.
While there is still much that we don’t understand about these phenomena, the study of NGC 1277 and other galaxies with massive black holes is helping us to learn more about the universe and the forces that shape it.
