Which is travelling the fastest: Earth in our solar system, Our solar system in our galaxy, or our galaxy moving through space?

All motion is relative. It depends what you measure their speed relative to.

They're all in the galaxy moving through space, so it's a trick question. BTW, without having any land mark to tell where empty space is, it's almost impossible to know how fast you are actually travelling through it. You can see how fast everything is moving away from you.

All at relative Velocities
The Milky Way against the Cosmic Microwave Background
The Sun and our Solar System through Our Galaxy
The Earth in its orbit which is approximately 33, 000 mph
New Horizons is on its way at 35, 000 mph towards its third and last Kuiper Belt Object, where it is to deploy the last remaining power that it has to use a Gravity assist and Slingshot itself out towards the Oort Cloud at 45, 000 mph
It will break V1's speed record and will eventually overtake it
Probably beating it to the Oort CloudSource(s): New Horizons at Pluto

Earth, relative to the Sun = 30 km/s = 108,000 km/h = 67,500 mph = 58,620 knots
Sun, relative to Galactic centre = 230 km/s = 517,500 mph
Galaxy, relative to Cosmic Background = 400 km/s = 900,000 mph
All these are approximate.
For example, Earth's average orbital speed is closer to 29,746 m/s

I don't know what you mean by "moving through space". Could you give a reference for this movement? All motion is relative, so we can't talk much about motion until we agree on a reference.
Relative to the Large Magellanic Cloud, our galaxy is moving at 278 kilometers per second. Relative to the Sagittarius dwarf galaxy, the speed is 140 km/s.

Depending on which point you measure it from, our galaxy moving through space...
Earth orbits the sun at about 66,600 mph.
Our solar system orbits the center of the Milky Way at about 515,000 mph.
Our galaxy is moving in relation to the Local Group's center of gravity at about 1.3 million miles per hour.

In relationship to what? Some arbitrary fixed point? There are no fixed points.

Apparently the galaxy moving through space. That is one reason why "transporters" will never work long-distance - everything isn't where it was just a second ago.)

The Galaxy traveling through space. The Galaxies are traveling apart and this has been accelerating. .

My guess is the galaxy moving thru space.
