NGC 681
NGC 681, also known as the Little Sombrero Galaxy, is a spiral galaxy located approximately 66.3 million light-years away in the constellation Aries. It is classified as an SA(rs)bc galaxy, indicating it's a spiral galaxy with a small ring structure and moderately wound spiral arms.
The galaxy is relatively small compared to the Sombrero Galaxy (M104) it resembles, hence the nickname. It exhibits a prominent central bulge, which is characteristic of many spiral galaxies. The disc of NGC 681 is seen nearly edge-on, contributing to its apparent resemblance to the Sombrero Galaxy.
NGC 681 is notable for its relatively high rate of star formation within its spiral arms. Studies of the galaxy have revealed a population of young, hot stars concentrated in these regions. These young stars contribute significantly to the galaxy's overall blue color.
It was discovered by William Herschel on October 2, 1786. It is part of the LGG 34 galaxy group.
