10m/s Orbit Speed landed on Minmus

[Loup]

Hello everyone first please forgive my english.

So my problem is basicaly dis one :

As you can see, there is a 10m/s speed coming from i dont know where, messed a lot with me when i wanted to land on Minmus.

I tried to "control from here" from the pod and from Mechjeb module.

Anyone would know what is it about?

Maybe a noobish thing i made as a mistake?

Again sorry for my english, and thanks to anyone who try to help me.

Minmus is rotating, what you are seeing is the speed of its rotation at your surface location. If you click the speed meter it will change from "Orbital" to "Surface" and should read 0.0m/s.

It shows because Minimus (along with all other planets/moons) are actually rotating. When you're sitting on the surface you're "orbiting" minimus at roughly 9.5m/s as that is your speed relative to the center of the planet.

If you're trying to land, what you need to do is click on the blue box that has Orbit in it. That will switch the velocity mode to "Surface" That will give you your speed relative to the surface below you, which will exclude the default 10m/s that Minimus spins at.

You can see a similar thing on Kerbin when launching a new ship by clicking on the same blue box (it should say surface when launching). It will go from "Surface 0m/s" to "Orbit 175m/s" because when you're on the surface of Kerbin you're moving at roughly 175m/s

Let me know if you have other questions on how that works.
