How to make an effect in a particle system so that it is always behind the sphere?
How to make the effect in the Particle System always be behind the sphere. In the independent direction of the movement of the sphere?
Fine. The effect behind the sphere. 
Bad. Side effect after changing the direction of the parent. It is necessary that there should be behind. 
Do not offset the particle system emitter position to the sphere, instead use “size/color over lifetime” module to make the beginning of the trail invisible.
