In this video, we will talk about the closest dwarf galaxy to our own Milky Way and discuss its future. As noted in the Wikipedia article you linked to, the existence of the Canis Major Dwarf Galaxy is hotly disputed and many authorities suggest that the “overdensity” in this direction is simply a sign of the corrugated wavy nature of the outer Milky Way, not a separate structure.

Because of this technique, the astronomers were able to detect a very significant over-density of class M giant stars in a part of the sky occupied by the Canis Major constellation, along with several other related structures composed of this type of star, two of which form broad, faint arcs (as seen in the image close to the top). Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. Called the Canis Major dwarf galaxy after the constellation in which it lies, it is about 25000 light years away from thesolar system and 42000 light years from the centre of the Milky Way.

The main body of the galaxy is already extremely degraded, a process which will continue as it travels around and through our Galaxy. This puts it closer to us than the center of our own galaxy, which is 30,000 light years away from the Solar System.

This stellar formation is about 42,000 light years from the galactic center, and a mere 25,000 light years from our Solar System. These can be satellite galaxies of Milky Way, satellite galaxies of Andromeda and other major galaxies including Andromeda. The new answer to this old question is the Canis Major dwarf galaxy. Hopkins Observatory in Arizona (for the Northern Hemisphere) and the Cerro Tololo Inter-American Observatory in Chile (for the southern hemisphere). The term "Milky Way" is a translation of the Classical Latin via lactea, from the Greek word galaxías meaning “milky circle". Most distant (difficult) naked eye object. Our nearest neighbor, Andromeda, is 2.5 million light years from Earth and the space between the Milky Way and Andromeda is populated with only a smattering of small galaxies, known as satellite galaxies. The galaxy's official discovery was made in 1994 by Gerry Gilmore and Mike Irwin, and it was described as the Milky Way’s nearest neighbor. 00:23:30 Isn't the buy in cost for Starlink too expensive?

Of these, most people consider the Andromeda Galaxy to be our closest galactic cohabitant. Leo I, the ghostly galaxy below the bright blue star Regulus, glittered with newborn stars while entering the Milky Way’s domain 2 billion years ago. The Sagittarius dwarf elliptical galaxy. 00:37:31 Is Andromeda more massive? But we do know that our Milky Way has a spiral nature from observations made from within our Galaxy (though whether or not it is a barred spiral is still being debated). The Canis Major Dwarf Galaxy Dwarf Galaxy is believed to contain one billion stars in all, a relatively high-percentage of which are in the Red Giant Branch phase of their lifetimes. The current theory is that this galaxy was accreted (or swallowed up) by the Milky Way Galaxy. So you could say the Milky Way has a lot of neighbors. the Canis Major Overdensity. And More…, Episode 697: Interview: Theoretical Physicist Dr. Peter Woit, Episode 696: Open Space 94: Is It Realistic to Declare a "Free Mars"?
