If the solar system were 10 cm across, how big would the Milky Way galaxy be on that scale? Use orbit of Neptune as the outer edge of the solar system. (Hint: The orbits of planets are ellipses, but they are nearly spherical, so you can use Neptune’s semi major axis as the approximate radius of a circular orbit. Use the appendix in your book). You must show your work for credit!
The orbit of Neptune is 30.1 AU (Astronomical Units)
1 AU = 1.5e8km
The Milky Way galaxy is 100,000 LY (Light Years) across
1 LY = 9.5e12km
i have no clue what to do... help me please..
speed of light is this 3e5 km/s
i dont even know what that means.. hopefully someone out there does
