Alright guys, trying to figure out the speed at which our galaxy moves for a part of the 95157 fic. Using that as a universal measurement of time.

Here is what I have. Our location (Earth) is approximately 28,000 light years from the center of our galaxy. This gives us a diameter of 56,000 light years. A circumference of 175840 light years. (56,000 X 3.14) (One rotation)

A web site I found

http://www.pd.astro.it/E-MOSTRA/NEW/A5005MWY.HTM

estimates at our lateral distance we travel at approximately 28 kilometers per second.

So, one light year, 299792.458 Kilometers per second / 28 KPS = 10706.8735 seconds to reach one rotation. / 60 = 177.447 minutes. / 60 = 2.974 hours to reach the distance light travels in one second? Do I have that right or am I full of sh#*ty numbers?

If I have that right it would take 10706 hours to reach one light year. Multiply that by the circumference and I get 214902.1735 years for one galactic rotation at our currenct distance.

.....If I got that right I'm buying myself a beer.....

Wow I was way off. Thanks Zeo.

Ok, I found my mistake. I was using one light year as the total distance.

Going by what was on Wiki I have

240 Kilometers per second x60 x60 x24 x 364 = (7547904000 kilometers travelled in one year)

27000 light years. ( Rough distance from core)

299792.458 Kilometer per second = speed of light.

1079252848.8 Kilometers per hour

25902068371.2 Kilometers per day

9,428,352,887,116.8 KPY = one light year in Kilometers.

254,565,527,952,153,600 = diameter of our suns rotation around core

799,335,757,769,762,304 = circumference

Circumference divided by distance travelled in one year equals 105,901,685.7885 Earth years to rotate once around galactic core at our distance.
