NGC 5098 belongs to the NGC 5098 [[galaxy group]] which is located some 560 million [[Light-year|light-years]] away.<ref>{{Cite web |title=NED Search Results for NGC 5098 GROUP |url=https://ned.ipac.caltech.edu/cgi-bi...&hconst=73.0&omegam=0.27&omegav=0.73&corr_z=1 |access-date=2024-05-09 |website=ned.ipac.caltech.edu}}</ref> They are the central galaxy pair, first identified by Ramella et al. 1995 "their group 80."<ref>{{Cite journal |last=Ramella |first=Massimo |last2=Geller |first2=Margaret J. |last3=Huchra |first3=John P. |last4=Thorstensen |first4=John R. |date=1995-04-01 |title=The Redshift-Space Neighborhoods of 36 Loose Groups of Galaxies.I.The Data |url=https://ui.adsabs.harvard.edu/abs/1995AJ....109.1458R |journal=The Astronomical Journal |volume=109 |pages=1458 |doi=10.1086/117375 |issn=0004-6256}}</ref> NGC 5098 NED01 is the brighter and larger of the two, showing [[Apparent magnitude|optical magnitudes]] of ''MB'' = −21.131 and ''MV'' = −22.097, as compared to ''MB'' = −20.845 and ''MV'' = −21.770 for NGC 5098 NED02, which the [[Magnitude (astronomy)|magnitudes]] were calculated from [[Sloan Digital Sky Survey]] by Adelman-McCarthy<ref>{{Cite journal |last=Adelman‐McCarthy |first=Jennifer K. |last2=Agüeros |first2=Marcel A. |last3=Allam |first3=Sahar S. |last4=Allende Prieto |first4=Carlos |last5=Anderson |first5=Kurt S.J. |last6=Anderson |first6=Scott F. |last7=Annis |first7=James |last8=Bahcall |first8=Neta A. |last9=Bailer‐Jones |first9=C.

NGC 5098 NED01 hosts an extended [[Astronomical radio source|radio source]], B2 1317+33 which was detected at several [[Frequency|frequencies]].<ref>{{Cite journal |last=Colla |first=G. |last2=Fanti |first2=C. |last3=Ficarra |first3=A. |last4=Formiggini |first4=L. |last5=Gandolfi |first5=E. |last6=Grueff |first6=G. |last7=Lari |first7=C. |last8=Padrielli |first8=L. |last9=Roffi |first9=G. |last10=Tomasi |first10=P. |last11=Vigotti |first11=M. |date=1970-03-01 |title=A catalogue of 3235 radio sources at 408 MHz |url=https://ui.adsabs.harvard.edu/abs/1970A&AS....1..281C |journal=Astronomy and Astrophysics Supplement Series |volume=1 |pages=281 |issn=0365-0138}}</ref> A study showed there is evidence of gas swooshing and [[active galactic nucleus]] (AGN) heating up which the most likely contributor is the nearby galaxy, NGC 5098 NED02 which is being stripped of its gaseous [[atmosphere]].<ref name=":1">{{Cite journal |last=Randall |first=S.

They are similar to X-ray [[Observation|observations]] of other galaxies, groups and [[Clusters of galaxies|clusters]].<ref name=":1" /> These are formed when active galactic nucleus (AGN) jets push into local ICM, evacuating cavities and creating bright rims of X-ray emission from displaced gas.<ref name=":1" />

A plume of [[Emission spectrum|emission]] is seen extending northeast from NGC 5098 NED01,<ref>{{Cite journal |last=Gastaldello |first=Fabio |last2=Buote |first2=David A. |last3=Humphrey |first3=Philip J. |last4=Zappacosta |first4=Luca |last5=Bullock |first5=James S. |last6=Brighenti |first6=Fabrizio |last7=Mathews |first7=William G. |date=2007-11 |title=Probing the Dark Matter and Gas Fraction in Relaxed Galaxy Groups with X‐Ray Observations from<i>Chandra</i>and<i>XMM‐Newton</i> |url=https://iopscience.iop.org/article/10.1086/521519 |journal=The Astrophysical Journal |volume=669 |issue=1 |pages=158–183 |doi=10.1086/521519 |issn=0004-637X}}</ref> exhibiting a [[spiral arm]] morphology which originates east from the galaxy and wrapping around to the [[north]]. This presence of a feature indicates NGC 5098 NED01 is indeed [[Interacting galaxy|interacting]] with NGC NED02.<ref name=":1" />

Apart from that, there is a sharp [[surface brightness]] to west, southwest and south, which is approximately 28 kpc from the central AGN of NGC 5098 NED01.<ref name=":1" /> It appears to go eastwards and define the outer [[boundaries]] of the arm, adding to the overall impression of the spiral pattern in diffuse emission. The edges are quite similar to features that are seen from cold fronts generated by [[gas]] sloshing in observations<ref>{{Cite journal |last=Dupke |first=Renato |last2=White III |first2=Raymond E. |last3=Bregman |first3=Joel N. |date=2007-12-10 |title=Different Methods of Forming Cold Fronts in Nonmerging Clusters |url=https://iopscience.iop.org/article/10.1086/522194 |journal=The Astrophysical Journal |volume=671 |issue=1 |pages=181–189 |doi=10.1086/522194 |issn=0004-637X}}</ref> and [[Simulation|stimulations]] of galaxy clusters and groups.<ref name=":2">{{Cite journal |last=Ascasibar |first=Yago |last2=Markevitch |first2=Maxim |date=2006-10-10 |title=The Origin of Cold Fronts in the Cores of Relaxed Galaxy Clusters |url=https://iopscience.iop.org/article/10.1086/506508 |journal=The Astrophysical Journal |volume=650 |issue=1 |pages=102–127 |doi=10.1086/506508 |issn=0004-637X}}</ref>

A study shows NGC 5098 NED02, does not show any traces of associate emission in [[X-ray|X-rays]], implying it was stripped of gas.<ref name=":1" /> It is possible NGC 5098 NED02 after being [[Ram pressure|ram-pressured]] stripped and passing east of NGC 5098 NED01 might have circled around it and now moving east, creating a conical wake in diffuse emission.<ref name=":2" />
