Question

Quizplus · Accepted Answer

The Milky Way Galaxy has a radius of about 100,000 light-years. Earth is located about 30,000 light-years from the center of the galaxy. Therefore, the ratio of the distance from Earth to the center of the galaxy to the total radius of the galaxy is 30,000/100,000, which simplifies to 3/10. To find the fraction of the way out from the center of the galaxy that Earth is located, we subtract this ratio from 1 (the whole distance), which gives us 1 - 3/10 = 7/10. Therefore, Earth is located 7/10 or 2/3 of the way out from the center of the Milky Way Galaxy.
