Arp 107 is a pair of interacting galaxies (designated separately as UGC 5984 and MCG+05-26-025) located about 450 million light-years away in the constellation Leo Minor. The galaxies are in the process of colliding and merging.{{cite web|url=http://www.spitzer.caltech.edu/images/2344-sig05-006a-Interacting-Galaxy-Pair-Arp-107|title=Interacting Galaxy Pair Arp 107|date=9 June 2005|work=Spitzer Space Telescope website|publisher=Spitzer Science Center, California Institute of Technology |accessdate=19 October 2012}}
Characteristics
Arp 107 is made of two separate galaxies. The larger galaxy to the left is PGC 32620, and the smaller galaxy to the right is PGC 32628, (as depicted in the Hubble image). These galaxies are different in which one is a spiral galaxy while the other one is an elliptical galaxy being connected by a bridge and tidal tail made of dust and gas.{{Cite journal |last1=Lapham |first1=Ryen C. |last2=Smith |first2=Beverly J. |last3=Struck |first3=Curtis |date=2013-03-28 |title=ULTRAVIOLET/OPTICAL/INFRARED COLOR SEQUENCES ALONG THE TIDAL RING/ARM OF Arp 107 |url=https://iopscience.iop.org/article/10.1088/0004-6256/145/5/130 |journal=The Astronomical Journal |language=en |volume=145 |issue=5 |pages=130 |doi=10.1088/0004-6256/145/5/130 |issn=1538-3881|arxiv=1303.3312 |bibcode=2013AJ....145..130L }}{{Cite web |last=Lazaro |first=Enrico de |date=2023-09-18 |title=Hubble Captures Stunning Collision of Two Galaxies {{!}} Sci.News |url=https://www.sci.news/astronomy/hubble-arp-107-12271.html |access-date=2024-08-16 |website=Sci.News: Breaking Science News |language=en-US}}
The nucleus of PGC 32620 is active and it is classified as a type 2 Seyfert galaxy.{{Cite journal |last1=Keel |first1=W. C. |last2=Kennicutt |first2=((R.

The most likely scenario for this appearance in PGC 32620, is that the elliptical galaxy penetrated through its disk, causing it to become semi-annular with a large single spiral arm protruding out. This spiral arm in turn, then branches out in a form of a tidal arm, where star-forming regions of both old and young star populations are present.{{Cite journal|arxiv=1303.3312 |doi=10.1088/0004-6256/145/5/130 |title=ULTRAVIOLET/OPTICAL/INFRARED COLOR SEQUENCES ALONG THE TIDAL RING/ARM OF Arp 107 |date=2013 |last1=Lapham |first1=Ryen C. |last2=Smith |first2=Beverly J. |last3=Struck |first3=Curtis |journal=The Astronomical Journal |volume=145 |issue=5 |page=130 |bibcode=2013AJ....145..130L }}File:APG107.jpg]]
