Question

What is earth's size relative to the galaxy?

Answer 1

it's puny compared to M87, an elliptical galaxy 980,000 light years in diameter. the milky way is only 100,000 light years in diameter.

Answer 2

ANSWER:

Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^(13).

That's the answer~
