A small irregular galaxy thought to orbit the Milky Way, trailing stars behind it to create a structure known as the Monoceros Ring. It should be noted that there is some dispute over the nature of the galaxy, but if current analysis proves to be correct, then this is the closest known external galaxy to the Solar System.

Optical and infrared studies showthat the closet dwarf galaxy, Canis Major (CMa), has an old massive coremainly populated by red giant branch (RGBs) stars. We propose to observethe center of CMa dwarf galaxy, which have not been yet observed in X-rays in order to analyse AWDs using X-ray and multi-wavelength data,and to perform a comparative ...

2023年3月8日 · The Canis Major dwarf galaxy isn’t the largest of the dwarf satellite galaxies that orbit the Milky Way. That honor belongs to Antlia II, a dwarf galaxy roughly 9,500 light-years in diameter and over 400,000 light-years away.
