How fast is the Earth traveling through Space?

andrewv..

Thanks for your question.  The Earth spins at a rate of approximately
1000 miles per hour and orbits the sun at about 67,000 miles per hour
or 29.78 kilometers per second.

Thanks again for your question.  If you need any additional
clarification, please let me know prior to rating my answer.

Great, quick response.

Meanwhile, the Sun is orbiting the centre of gravity of the galaxy at
a rate half a million miles an hour or so, taking about 230 million
years to go around once; and the whole galaxy, together with other
members of the local group is heading towards Virgo at a rate of about
a million miles an hour, and the whole Virgo; and the Virgo cluster of
speeding towards the "great attractor".

Also note, the 1000mph of the earth's rotation applies only at the
equator.

oops - that last bit should read:
"and the whole Virgo cluster is speeding towards the "great attractor".
