re: Spaceship Earth !
30 km/sec around the sun...
20 km/sec towards Lambda Herculis.
The sun at 218 km/sec around the galaxy.
Our galaxy at 80 km/sec towards Andromeda.
The general motion of our galaxy is towards the Leo Triplets, M96 and at a speed of 583 km/sec
But the net motion (relative to the Cosmic Background) is at 552 km/sec towards the center of Hydra.
Our Spaceship Earth travels the distance of 1 light-year in 1,400 years !!!
Well, ok, sources don't agree with all the speeds (and our motion isn't the same in january as in july), but it's the idea.
