SDSS J092048.27+302818.3 also known as OGC 330 and SHELS J140.2012763+30.4717820 is a elliptical galaxy located in the constellation of Cancer. The redshift of the galaxy is (z) 0.288.[1]

SDSS J092048.27+302818.3 is a massive elliptical galaxy of Type E morphology, residing as the brightest cluster galaxy of the GMBCG J140.20117+30.47176 galaxy cluster. The total R-band magnitude of the galaxy has been estimated to be 16.903 ± 0.001 while its total stellar mass is calculated to be 11.89+0.06−0.08 M☉.[2][3][4]

The total half-light radius of the galaxy has been estimated to be 2.7396 ± 0.0058 or 4.25 arcseconds while the axial ratios is calculated to be 0.9278 ± 0.0009.[5][6] Evidence also found it is an early-type galaxy shown lensing an emission-line galaxy located in the background with a redshift of (z) 0.3918. The stellar velocity dispersion of the galaxy itself is 297 ± 17 kilometers per seconds while the major axis position angle of the galaxy is 30°. The total AB magnitude is 16.25.[6] A study published in 2022 has recalculated the stellar mass of the galaxy as 11.786+0.092−0.120 M☉.[7]
