GSFC This star is also a variable, having a medium apparent magnitude of 4.40, which varies from 4.36 to 4.40. The Canis Major Galaxy is closer to our Solar System than the centre of the Milky Way. The discovery of the CMa and subsequent analysis of the stars associated with it has provided some support for the current theory that galaxies may grow in size by swallowing their smaller neighbors. Canis Major Dwarf Galaxy. The brightest star in Canis Major is Sirius, the brightest star in the sky and the fifth nearest to Earth, at a distance of 8.6 light-years. [5] Some research suggests that the trail of stars is actually part of the warped galactic thin disk and thick disk population and not a result of the collision of the Milky Way with a dwarf spheroidal galaxy. published December 04, 2018 The Large Magellanic Cloud (LMC) is a satellite dwarf galaxy of the Milky Way that is among the closest galaxies to Earth. The Canis Major Dwarf Galaxy lies some 25,000 light-years from Earth's solar system and about 42,000 light-years from the centre of the Milky Way, which makes it the closest galaxy to the Milky Way found to date. The Canis Major Dwarf Galaxy, also known as the Canis Major Overdensity, is an irregular galaxy that is thought to be the closest neighboring galaxy to our solar system. NGC 1261 is another nearby cluster, but its velocity differs enough to make its relationship to the system unclear. Privacy Policy and Important Notices ASD at It is one of largest stars known (sometimes described as the largest known) [64] and is also one of most luminous with a radius varying from 1,420 to 2,200 times the Sun's radius, and a luminosity around 300,000 times greater than the Sun.

There are the same types of dwarf galaxies as there are with normal sized galaxies, i.e. It's about 50,000 light-years away from the Milky Way center. I doubt that you could find us as a target for travel from that distance. Around 6 billion years from now, the two galaxies will merge to form a single galaxy. It is located within our galaxy, The Milky Way but given its distance from our planet, Earth, it is simply too far away for any human or space probe to visit with current technology. The closest galaxy to us is called the "Canis Major Dwarf Galaxy" and is over 42000 light-years away from the center of our Milky Way, however just around half that away from Earth (25000 light-years). This is currently our closest galactic neighbor, yet it still seems to be an impossible distance away.

There's no register feature and no need to give an email address if you don't need to. 2019-09-09. Its not the first dwarf galaxy to have merged with our galaxy, it certainly will not be the last. Because of this technique, scientists were able to detect a very significant overdensity 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. Recent measurements indicate that the Canis Major dwarf is only 42,000 light years from the As rough guide, the location is located in the constellation of Pisces. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now. NGC 2359 - Thor's Helmet Answer (1 of 2): Surely, you jest. We obtain l cos b = -1.47 0.37 and b = -1.07 0.38 mas yr-1, on the International Celestial Reference . Globular clusters thought to be associated with the CMa include NGC 1851, NGC 1904, NGC 2298 and NGC 2808, all of which may have been part of the galaxy's globular cluster system before accreting into the Milky Way. Jerry Bonnell (UMCP) Likely main-sequence stars in CMa have been selected from a region in the color-magnitude diagram that has very little contamination from known Milky Way components. (LMC) was closest, but its title was supplanted in 1994 by the The galaxy has over a billion stars but is difficult to observe as it is obscured by the milky way. It orbits over the top and down below the disk of our galaxy, like a ring over a spinning top. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment.
