The Orion's Arm Universe Project Forums

'Oumuamua is travelling very slowly, so is not a very good model for an interstellar spacecraft. In fact it is travelling at more or less the same rate as the Local Standard of Rest - that is to say, it is travelling at roughly the same speed as all the other stars in the Orion Arm if they were averaged out. The main reason it appears to be moving with respect to the Solar System is that we are not moving at exactly the same speed as the LSR.
