What is translational velocity and how does it differ from rotational velocity? (1 Viewer)

What is translational velocity?

HELP ME PLEASE!

Ok, I know that rotational velocity is simply the velocity at which the star rotates (how quickly it is spinning). Jacaranda talks about 'real velocity', 'space velocity' and 'proper motion' << which one is translational velocity?

I know this is in the 'wrong part of the forum', but I already posted this question in the Astrophysics section and that proved a dead end (seriously, its dead over there)

anyone?

translational velocity would be the velocity which the center of mass actually moves... i am not faimilar with astro syllabus, so not sure which frame of reference would u be taking...

translational velocity arises from revolving. I don't have the jacaranda book with me but i guess it refers to "space velocity"
