pluto, lacks sufficient mass to produce electromagnetic radiation
or is sufficiently distant as to not interfere with electromagnetic radiation on Earth
unable to reflect electromagnetic radiation from the Sun
and from the other Planets to Earth
so as to produce a noticeable affect proven by Science.
How could science deem anything noticeable or not? That is a completely subjective opinion. Any planet that can be seen from Earth with a telescope is obviously sending electromagnetic waves towards us. If it has an effect, no matter how minor, it has an effect. Just because its effects are very small does not constitute completely dismissing it.
