Could someone give the rough estimates of speeds of our travel through space?
I can easily find the two nearby ones:
- Earth's own rotation - depending on latitude, up to 40,075 km/24h = 463 m/s
- Earth's orbital speed around the Sun - 940 000 000 km/year = 29,786 m/s
Now how do these fare?
- Motion of Sun within the arm of the galaxy, around the center of the galaxy?
- Motion of the galaxy within the local supercluster?
- (if possible to measure at all) movement of the supercluster within the universe?
