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], and 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]
