I was going to redo my code to interpolate between
steps for the perihelion advance but it will take
some effort and it is pointless if you don't accept
the path is valid anyway so I'll just correct this:

If an object moves 3m and then another 5m in the
same direction, it has moved 8m in that direction.
We call that displacement. Displacements add.

Velocity is the rate at which displacement happens,
it is just the displacement divided by the time
taken so velocities add.

Acceleration is the rate at which velocity changes,
it is just the change of velocity divided by the
time taken so accelerations add.

Displacement, velocity and acceleration are all
vectors

/Vectors/

The method used in my code uses x and y components:

/Vectors/ #Rectangular

Learn the basics Max, this is trivial schoolboy maths.
