Are there any stars known to be moving towards our solar system faster than any other star?

I'm contemplating the likelihood of the theory that our sun is part of a binary star system. If such happens to be true and our star's twin is moving towards us, might that explain some of the warming-up seen on Earth and allegedly seen on other planets as well?Are there any stars known to be moving towards our solar system faster than any other star?Barnard's Star has radial velocity of about -110 km/s. "Barnard's Star will make its closest approach to the Sun around AD 11,700, when it approaches to within about 3.8 light-years.[16] However, at that time, Barnard's Star will not be the nearest star, since Proxima Centauri will have moved even closer to the Sun.[17]"



Alpha Centauri's radial velocity is about -25 km/s. Now 4.65 ly away, it will pass within 3.26 ly ca. 29,700 CE, before moving away.



It is inconceivable that this has anything to do with global warming. That sounds like something an astrologist would dream up.
