NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, similar to the distance of M101 in the constellation Ursa Major. Both were once considered to be part of the Local Group, but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.

This galaxy is located at a distance of 40 million light-years (12.3 Mpc) from the Milky Way. It is interacting with UGC 5983, a nearby dwarf galaxy, and features tidal filaments and intense star formation. Because of these features, it was listed in Halton Arp's Atlas of Peculiar Galaxies.
NGC 5579 is an intermediate spiral galaxy in the northern constellation of Boötes. It was discovered on May 1, 1785) by German-British astronomer William Herschel. The galaxy is located at a distance of 179 ± 14 million light-years (54.9 ± 4.3 Mpc) from the Milky Way, and is receding with a heliocentric radial velocity of 3,608 km/s. It is entry 69 in Halton Arp's Atlas of Peculiar Galaxies.
UGC 8335 is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies.
NGC 4490, also known as the Cocoon Galaxy, is a barred spiral galaxy in the constellation Canes Venatici. William Herschel discovered it in 1788. It is known to be of the closest interacting/merging galactic system. The galaxy lies at a distance of 25 million light years from Earth making it located in the local universe. It interacts with its smaller companion NGC 4485 and as a result is a starburst galaxy. NGC 4490 and NGC 4485 are collectively known in the Atlas of Peculiar Galaxies as Arp 269. The two galaxies has already made their closest approach and are rushing away from each other. It's been discovered that NGC 4490 has a double nucleus.
NGC 2444 is a peculiar lenticular galaxy in the constellation Lynx. The galaxy lies about 135 million light years away from Earth, which means, given its apparent dimensions, that NGC 2444 is approximately 50,000 light years across. It was discovered by Édouard Stephan on January 18, 1877. The galaxy interacts with another galaxy, NGC 2445, whose shape is distorted and has large star formation regions.
UGC 717 is a barred spiral galaxy located in Pisces. The galaxy is located 520 million light-years away from the solar system. It is designated as Arp 11 in the Atlas of Peculiar Galaxies which was produced by Halton Arp. UGC 717 falls under the category of spirals that have split-arms. It is known to have a LINER active galactic nucleus according to SIMBAD.
Arp 146 are a pair of interacting galaxies located 1.05 billion light-years away from Earth in the Cetus constellation. According to a study, one galaxy appears to have passed through another, leaving behind a ring formed from the bridge material and remnants of the nucleus. Under the Atlas of Peculiar Galaxies created by Halton Arp, they are categorized under galaxies that have associated rings.
PGC 4789 is a distant barred spiral galaxy in the Pisces constellation. It is located 675 million light-years from the Milky Way and seems to be interacting with its neighboring galaxies. it is known as Arp 48 in the Atlas of Peculiar Galaxies catalogue. In this class, PGC 4789 falls into galaxies that have at least one low surface brightness companion.
UGC 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation. It is located 500 million light-years away from the solar system and has a diameter of 290,000 light-years, making it slightly more massive compared to the Milky Way. The galaxy is moving away at a speed of 11,162 kilometers per second.
UGC 4881 is a pair of interacting galaxies, UGC 4881A and UGC 4881B. They are located in the constellation Lynx, some 500 million light-years away. UGC 4881, the brighter, is a peculiar spiral galaxy. It has been heavily documented by the Hubble Space Telescope, and is cataloged in the Atlas of Peculiar Galaxies.
UGC 1840 known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the Solar System in the Andromeda constellation. Made up of two galaxies, UGC 1840 NED01 and UGC 1840 NED02, the two galaxies had recently collided with each other in which the elliptical galaxy has penetrated through the spiral galaxy's nucleus leaving a hole in its middle, thus forming a ring galaxy. With a diameter of 1.3 arc minutes, close to 100,000 thousand light-years, they are roughly the same size as the Milky Way.
NGC 3995 is a Magellanic spiral galaxy in the constellation Ursa Major. The galaxy lies about 100 million light years away from Earth based on the Tully–Fisher relation, which means, given its apparent dimensions, that NGC 3995 is approximately 80,000 light years across, while based on redshift it lies 170 million light years away. It was discovered by Heinrich d'Arrest on February 5, 1864.
UGC 6697 is a large irregular spiral galaxy with a bar located in the Leo constellation. It is located 378 million light-years from the solar system and has an estimated diameter of 205,000 light-years. UGC 6697 is considered a starburst galaxy which produces high rates of star formation.
NGC 3509 known as Arp 335, is a barred spiral galaxy located in the constellation Leo. It is located 340 million light-years from the Solar System. NGC 3509 was discovered by astronomer William Herschel on December 30, 1786.
NGC 3800 is an intermediate spiral galaxy located in the constellation Leo. Its speed relative to the cosmic microwave background is 3,653 ± 24 km/s, which corresponds to a Hubble distance of 53.9 ± 3.8 Mpc. NGC 3800 was discovered by German-British astronomer William Herschel in 1784.
NGC 6365 is a pair of spiral galaxies in the constellation Draco. It consists of two galaxies, PGC 60174 to the south, and PGC 60171 to the north. These two galaxies are also designated respectively by the NASA/IPAC database as NGC 6365A and NGC 6365B. This pair of galaxies was discovered by German astronomer Lewis Swift in 1884.
