A summary of these methods: 1  Cepheid variable stars and their cousins the RR Lyrae stars are the primary distance indicators in the galaxy and the local group. 2  They pulsate radially (basically at the sound speed in the envelope of the star) with a period inversely proportional to the square root of the density.
Dividing this by 500 we arrive at: 31557600/500 = 63115.2 ~~ 63000  AU per light year. color(white)() How far away is the nearest galaxy from the Milky Way? The very nearest galaxy would be one of the small satellite galaxies. There are about 50 galaxies within about 1.4 million light years of the Milky Way. The closest are about 1000 light years from the edge, which by our reckoning would be about 63000000 = 6.3 xx 10^7 AU from the edge.
