NGC 4298 is a flocculent [3] [4] [5] [6] spiral galaxy located about 53 million light-years away [7] in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 [8] and is a member of the Virgo Cluster. [9] [10] [11]

NGC 4298 may harbor an intermediate-mass black hole with an estimated mass ranging from 20,000 (2×104 M☉) to 500,000 (5×105 M☉) solar masses. [12]

Interaction with NGC 4302

NGC 4298 appears to form a pair with [13] [14] [15] and appears to interact with NGC 4302. [13] [2] [14] [16] [15] [17] [18] [4] Evidence for an interaction between the two galaxies are that NGC 4298 exhibits a lopsided, asymmetrical distribution of stars, [4] [16] [15] a tidal bridge that connects it to NGC 4302, [18] [17] [2] a prodigious rate of star formation [19] and an HI-tail. However, the tail is also the result of ram pressure. [3]

The two galaxies are separated from a projected distance of ~36,000  ly (11  kpc). [20] [15] [3]

Ram-pressure stripping

The presence of a truncated gas disc, [3] [4] an asymmetric 6 cm polarized radio continuum distribution, [13] an HI-tail, [3] and asymmetries of gas in a similar direction as the ram pressure stripped gas in NGC 4302 suggest that NGC 4298 is under going ram pressure. [2]
