electromagnetic forces
according to PhD, Theoretical Physics, Professor Benjamin Schumacher of Kenyon College, electromagnetic forces tend to cancel out over distance.
Magnetic fields vary as the inverse-square of the distance between bodies.
F( magnetic field ) varies as 1 / r-squared.
Solar magnetic field is around 0.5-millitesla.
A kitchen magnet has a field strength which is 10X or 100X that of Earth's ( My data is scattered enough that I couldn't put my hands on the specific value ).
Sunspots have 0.2-0.3-millitesla magnetic fields.

Gravitational forces act between all bodies, throughout the Universe, regardless of distance.
