The interesting thing is, we can only measure our velocity in relation to other things. As far as we know, there's no absolute coordinate system for us to know our "true absolute velocity." Einstein had a lot to say about this.

The gravitational pull between the Earth and Sun causes the Earth to travel around, or "orbit", the Sun at a velocity of 29.8 km/sec. At the same time, the Earth also turns on its axis causing the daily cycle of day and night. This "rotational velocity" is approximately .47 km/sec.

Standing on the equator, the rotating of the earth means you'd be moving at 1000 miles an hour (relative to the pole).
The earth is orbiting the sun at about 65,000 miles an hour.
And the sun, and its surrounding stars are orbiting the center of the galaxy at (very) approximately 650,000 miles an hour.

The first responder is right. You need a reference. So, if we make the sun the reference, then the velocity of the sun is zero.
The velocity of the earth, beint 8 light-seconds from the sun, is approximately *2*pi light-seconds per year.
