This is how our galaxy became known as the Milky Way.There are about 200 billion stars in the Milky Way , including the sun. If you tried to count themone by one,it would take you over 3000 years! The thickest part of the Milky way is about 10000 lightyeats. The diameter(半径) of...
so the diameter of the Milky Way galaxy is about 9.5 x 1017km in diameter. The thickness of the galaxy ranges depending on how close you are to the center, but it’s tens of thousands of light-years across.
Astronomers have also calculated that the diameter of the Milky Way’ssupermassive black holeis around 14.6 million miles (23.5 million kilometers) . This is tiny compared to the Milky Way itself, which is 100,000 light-years wide and 1,000 light-years thick. Also dwarfing Sagittarius ...
Researchers also found that the galaxy's disk has a diameter of about 140, 000 light years. Each light year is about 9 trillion kilometers. (1) How did the researchers draw the map of the Milky Way? A.By studying its four major arms. B.By observing its shape in different places. ...
NASA says that "The Voyagers are destined—perhaps eternally—to wanderthe Milky Way." NASA说:“旅行者注定 - 也许永远 - 会漫游在银河系中。 LASER-wikipedia2 In other words,the Milky Wayhas a diameter of 100,000 light-years. 换句话说,银河系的直径是10万光年。
Although it has long been known that the Milky Way galaxy has a distinct spiral structure, our position within the galaxy has thus far precluded astronomers from determining the diameter of the galaxy with any degree of accuracy. Various models of what the Milky Way might look like when seen ...
At length, thanks to modern art, instruments of still higher perfection searched the moon without intermission, not leaving a single point of her surface unexplored; and notwithstanding that her diameter measures 2,150 miles, her surface equals the one-fifteenth part of that of our globe, and ...

The Milky Way is a large barred spiralgalaxycomprising an estimated 200 billion stars (some estimates range as high as 400 billion) arrayed in the form of a disk, with a central elliptical bulge (some 12,000 light-years in diameter) of closely packed stars lying in the direction of Sagitta...
