No there is one much closer. Our solar system is actually binary, like 90% of the stars out there. There is a brown dwarf that has something like a 27 million year orbit. NASA sighted it back in the 80's when they put up an infrared satellite.
If u read velikovsky he talks about venus coming into the solar system like a comet, hence it being called the wandering star. Check out symbols of an alien sky by the thunderbolts project.

Also research the electric universe. It explains our solar system much better where observations actually make sense instead of just making something up to explain observed discrepancies i.e. dark matter.
