4. The Canis Major Dwarf Galaxy (CMa Dwarf) or Canis Major Overdensity (CMa Overdensity) is a disputed dwarf irregular galaxy in the Local Group, located in the same part of the sky as the constellation Canis Major.. Credit: APOD . It has recently been settled by the Solarian Kingdom. The constellation of Canis Major contains several interesting deep-sky objects as well, such as the Canis Major Dwarf Galaxy, the open cluster Messier 41, the emission nebula NGC 2359 – also known as Thor’s Helmet, or the colliding spiral galaxies NGC 2207 and IC 2163. The Canis Major Dwarf is an irregular dwarf galaxy that is a satellite of our own Milky Way Galaxy. Recent observational evidence suggests that the Sagittarius dwarf galaxy represents the only major ongoing accretion event in the Galactic halo, accounting for the majority of stellar debris identified there. At present, the closet known galaxy to the Milky Way is the Canis Major Dwarf Galaxy – aka. Recent measurements indicate that the Canis Major dwarf is only 42,000 light years from the Galactic center, about three quarters of the distance to the Sagittarius dwarf and a … The galaxy is situated approximately 75,000 light years away from the Sun. The Canis Major Dwarf Galaxy is classified as an irregular galaxy and is now thought to be the closest neighboring galaxy to the Earth's location in the Milky Way, being located about 25,000 light-years (7.7 kiloparsecs) away from the Solar System[2] and 42,000 ly (13 kpc) from the Galactic Center.

The Canis Major Dwarf Galaxy (CMa Dwarf) is an irregular galaxy, roughly elliptical in shape, that is believed to be the nearest neighbouring galaxy to the solar system. It is not located in the Solar System. [5] Some research suggests that the trail of stars is actually part of the warped galactic thin disk and thick disc population and not a result of the collision of the Milky Way with a dwarf spheroidal galaxy. The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun.
