Jupiter's speed through space is a bit tricky to define, as it depends on what frame of reference you're using. Here are two ways to think about it:

1. Orbital Speed:

* Jupiter orbits the Sun at an average speed of 13.1 km/s (8.1 miles/s). This is about 47,500 km/h (29,500 mph).

* This speed varies slightly throughout its elliptical orbit, reaching its fastest near the Sun and slowest when furthest away.

2. Solar System's Motion:

* The entire solar system, including Jupiter, is moving through the Milky Way galaxy.

* The Sun's speed around the galactic center is about 220 km/s (137 miles/s), which is about 800,000 km/h (500,000 mph).

* This means Jupiter is also moving at this speed, but it's orbiting the Sun at the same time, so its actual motion is more complex.

So, in a nutshell:

* Jupiter orbits the Sun at a speed of 13.1 km/s.

* The entire solar system, including Jupiter, is moving through the galaxy at 220 km/s.

It's important to note that these are just averages, and the actual speed of Jupiter will vary depending on its position in its orbit and the solar system's movement through the galaxy.
