How to dock two objects with same velocity?

[Chris2004**]

I have two objects, a main station with no RCS, or engine, and a power plant part with a poodle engine, RCS, and about half a tank of fuel. They are both is a similar orbit but have a similar velocity and seem to stay the same distance away from each other. Any tips to fix this? Thanks and have a great day!!!

Docking has two parts, the rendevous where you get close to each other, and the actual docking. Rendevous is not too hard, but docking a craft to a station that can't rotate is pretty difficult until you practice a lot.

For rendevous, If they're in the same orbit then they'll stay the same distance from each other. How far are the two crafts from one another? If it's not too far (< 20km), select the other target in the Map, switch the NavBall to Target, and burn toward the pink Target Prograde marker. Once you get close, or if the green prograde drifts too far form the target prograde, burn on the green velocity retrograde marker to bring yourself to a stop, and repeat. Once you're better at this, you can push / pull the velocity marker to approach much faster.

If the two crafts are not currently close to each other, you need to get yourself into a different orbit. Pick a point where the two orbits are the closest/touching, and then burn prograde (if ahead) or retrograde (if behind). It doesn't have to be too much. Eventually, you or the other craft will catch up.

This old guide is pretty good:

or just burn prograde to accelerate so the orbits are not the same, and make manuever at Ap with which you will encounter the other vessel.

on the necounter, just burn retrograde (navbal must be set to "target") until you get 0 velocity.

than just slowly approach the vessel with RCS or wthevr.

Thank you both!!!! I will try today to get them closer and dock them. Have a great day!!!!
