Question
How fast does the MilkyWay orbit the Universe's Galactic Core
Andrew,
The universe is centerless!
It is also "same" in all directions..(isotropic).
So hunting about for a galactic core would be pointless.
For sure, the milky way is gravitationally bound to M31, the Andromeda Galaxy, its two satellite galaxies, and the milky way's own satellites the large and small Magellanic clouds.
This is called the local group of galaxies, it has some more members too, and this local group shares the hubble expansion of space.
Together, the group is hurtling towards the Super cluster of galaxies in the virgo cluster at about 600 km/sec.
This is because a huge amount of dark matter is attracting galaxies towards it since a long time.
Have a loook at the cluster on the hubble heritage site on the web.
Just type "hubble heritage" into google.
Hope that suffices.
Jayen
