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.

2020年3月27日 · NGC 4618, classified as a barred spiral galaxy, has the special distinction among other spiral galaxies of only having one arm rotating around the center 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.

2017年11月17日 · At first astronomers assumed that this high star formation rate was being triggered by the interaction with another, nearby dwarf galaxy called NGC 4618. They speculated that NGC 4618 may be the culprit “harassing” NGC 4625, causing it to lose all but one spiral arm.

2023年9月11日 · Below, a multispectral (and of necessity, false-color) image of NGC 4625 and its companion, NGC 4618, combines radio imaging of cool hydrogen gas (in purple) with a visible light image (in red) and near and far ultraviolet radiation (in green and blue, respectively).

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).

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。 与大多数 螺旋星系 不同，NGC 4618有一个单一的螺旋臂，这使星系呈现出不对称的外观。 这个星系被列入“特殊星系图集”，作为附近的三个单旋臂星系的例子之一。 虽然NGC 4618被标记为特殊星系，但也发现了许多相似的星系。 据推测，这个星系的不对称结构可能是与NGC 4625引力相 …

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...
