What are the Large and Small Magellanic Clouds, and the Sagittarius and Canis Major Dwarfs? The Large and Small Magellanic Clouds are two small galaxies that orbit the Milky Way at distances of some 150,000 and 200,000 light-years, respectively and they are both visible to the naked eye in the Southern Hemisphere.

What are the Large and Small Magellanic Clouds and the Sagittarius and Canis Major dwarfs chegg?
The Large and Small Magellanic clouds and the Sagittarius and Canis Major dwarfs are small galaxies orbiting the Milky Way.
What is the Large Magellanic Cloud and the Small Magellanic Cloud?
The Magellanic Clouds are irregular galaxies that share a gaseous envelope and lie about 22° apart in the sky near the south celestial pole. One of them, the Large Magellanic Cloud (LMC), is a luminous patch about 5° in diameter, and the other, the Small Magellanic Cloud (SMC), measures less than 2° across.
What are the Sagittarius and Canis Major dwarfs?
Both Magellanic Clouds are visible to the naked eye from the southern hemisphere. — The other two galaxies lie even closer to the milky way than the Magellanic Clouds, these two galaxies are known as Sagittarius Dwarf and Canis Major Dwarf. Both are are in process of colliding with the Milky Way's disk.
What are the two Magellanic Clouds?
The Magellanic Clouds are comprised of two irregular galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which orbit the Milky Way once every 1,500 million years and each other once every 900 million years.
What kind of objects lie in the halo of our galaxy?
Halo stars are made entirely of hydrogen and helium with no heavy elements. What evidence suggests that the protogalactic cloud that formed the Milky Way resulted from several collisions among smaller clouds?
How can we see through the interstellar medium?
Interstellar reddening occurs because longer wavelengths pass Interstellar reddening occurs because longer wavelengths pass through dusty clouds more easily. We can “see” through dust clouds in red, infrared and radio light.
Where Can You Find Large Magellanic Clouds?
The Large Magellanic Cloud lies in both the constellations Dorado and Mensa. Draw a line from Sirius past the right side of Canopus to find it. The Large Magellanic Cloud is found in the constellations Dorado and Mensa. The nearby star is Canopus.
What are Magellanic Clouds quizlet?
What are the Magellanic Clouds? two small galaxies that orbit the Milky Way Galaxy. How do disk stars orbit the center of the galaxy? They all orbit in roughly the same plane and in the same direction.
What is inside the Canis Major Dwarf Galaxy?
The Canis Major Dwarf This galaxy is also being pulled apart by the Milky Way's gravity — as it orbits the Milky Way, it is leaving a long filament of stars, gas, and dust in its wake. This 200,000 light year-long filament is known as the Monoceros Ring, and actually wraps three times around our galaxy!
