IC 4026 is a lenticular galaxy located in Coma Berenices.[1] It is located 315 million light-years away from the Solar System and has an approximate diameter of 70,000 light-years which is less the size of the Milky Way.[2] IC 4026 was discovered on May 11, 1896, by astronomer Hermann Kobold[3] and is a member of the Coma Cluster.[2][4][5] It has a surface brightness of 11.99 mag/arcsecs meaning it is a high surface brightness galaxy.[6]
IC 4026 shows a bar, indicating it might a barred lenticular galaxy of S0 morphology.[7][8][9] It has a central budge and an outer disc structure.[10]
To date, six redshift measurements give IC 4026 a distance of 92.483 ± 18.339 Megaparsecs or equivalent to (~ 302 Mly). This value is outside the Hubble Distance values.[11]
