NGC 4618 is a distorted barred dwarf galaxy in the constellation Canes Venatici. The galaxy is formally classified as a Sm galaxy, which means that its structure vaguely resembles the structure of spiral galaxies. The galaxy is sometimes referred to as a Magellanic spiral because of its resemblance to the Magellanic clouds.

NGC 4618是一个扭曲的棒矮星星系，位于猎犬座。 这个星系被正式归类为Sm星系，这意味着它的结构与螺旋星系的结构很相似。 星系有时被称为麦哲伦螺旋，因为它与麦哲伦云相似。

2020年3月27日 · NGC 4618, classified as a barred spiral galaxy, has the special distinction amongst other spiral galaxies of only having one arm rotating around the centre of the galaxy. Located about 21 million light-years from our galaxy in the constellation Canes Venatici, NGC 4618 has a diameter of about one third that of the Milky Way.

NGC 4618 is a Barred Spiral Galaxy located in the constellation of Canes Venatici in the northern hemisphere. NGC 4618's distance from Earth is 23,623,506.44 light years. NGC 4618 is called NGC 4618 in the New General Catalogue (NGC).

2014年4月3日 · NGC 4618 (left) is a large, one-armed spiral galaxy located in the constellation Canes Venatici. The smaller, compact-looking galaxy to the right is NGC 4625. In this visible light image, spiral arms are very difficult to see, which originally led astronomers to believe it was a fairly plain and old galaxy.

2024年4月7日 · NGC 4618 is a single-armed, barred spiral galaxy. The asymmetry of the arm being more prominent to the south of the bar is due to interaction with nearby NGC 4625, however recent studies have shown that may be only a partial explanation and that the lopsided arm structure may be due to intern...

NGC 4618 and NGC 4625 are both single armed dwarf galaxies about 25 MLy's away in the constellation Canes Venatici. It is thought that they are both single armed due to gravitational interactions bet...
