ESO 540-030 is a faint dwarf galaxy in the Sculptor Group.[1] It has the appearance of a massive scattering of dim stars.
The galaxy is located slightly more than 11 million light-years from Earth. It is difficult to observe due to galaxies situated behind ESO 540-030, and five bright stars between the galaxy and the Solar System.[3] The brightest of them is located around 1500 light-years away from us.[4]
