That's a great question! It's tricky to pinpoint exactly which planet travels at 110,000 kph because a planet's orbital speed changes throughout its orbit.

Here's why:

* Elliptical Orbits: Planets don't travel in perfect circles around the Sun. Their paths are slightly elliptical, meaning they're closer to the Sun at some points than others.

* Gravity's Influence: The closer a planet is to the Sun, the stronger the gravitational pull, and the faster it needs to move to avoid falling in.

Instead of a specific speed, we talk about average orbital speeds.

Here's a quick rundown of approximate average orbital speeds:

* Mercury: 170,500 kph

* Venus: 126,000 kph

* Earth: 107,000 kph

* Mars: 86,000 kph

* Jupiter: 47,000 kph

* Saturn: 35,000 kph

* Uranus: 24,000 kph

* Neptune: 19,000 kph

As you can see, Earth's average orbital speed is pretty close to 110,000 kph, but it fluctuates throughout its orbit.
