Re: How BIG is our GALAXY?
Posted By: Physalis <megatonage@hotmail.com>Date: 4/2/02 3:42 p.m.

In Response To: Re: How BIG is our GALAXY? (*Ar-Isildur of *WP*)

Bleah. Some data: radius of Home Galaxy: 50,000 light years. radius of Halo Killsphere: 12,500 light years. Or 4 Halos to reach across the diameter of the galaxy.

The galaxy is not a pure disc, it also has a sphere of thinly scattered stars above and below the main disc, appropriately known as its halo. Assume diameter of this sphere is equal to diameter of galactic disk. Assume we want to kill whatever's in the galactic halo.

Volume of galaxy = 4/3 * PI * radius of galaxy cubed = 5.24*10^14 ly^3.
Volume of killsphere = 4/3 * PI * radius of killsphere cubed = 8.181*10^12 ly^3.
Approximate number of killspheres to fill galaxy: Vgalact/Vkill = 64, or 4 cubed.

Seven???
