An eclipsing binary star is a binary star in which the orbit plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. Visible from Earth only when our planet wobbles. The axis of planet Earth in the last decade has shifted more then we been told.
Sedna belongs to the planetary system of the sun’s companion star.
If you want to fall for NASA official explanations: sun flare, atmospheric reflection, sundog etc…its your own choice.
Just be aware that the ones that own NASA are not as truthful as many people believe:
Nexus/Superwave will transform both of the stars. The companion star is not Brown dwarf but another yellow dwarf type of star. After turning them both into white dwarfs they will start to attract each other with gravitational force and collide forming a new star…a new begging for the human race…
