Gliese 710 (HD 168442, HIP 89825)
Gliese 710 (HD 168442, HIP 89825) is an orange dwarf star (type K7) in the constellation Serpens that is moving more-or-less directly
towards the solar system. Calculations indicate that it will pass within
1.1 light-years of the Sun in 1.5 million years time – close enough
possibly to disrupt planetary orbits and cause perturbations of objects
in the Oort Cloud that would send a shower
of comets and asteroids into the region of the inner planets.

The closest "recent" encounter between our solar system and another star
took place about 500,000 years when Gliese 208 came within 4 light-years
of the Sun – a bit closer than our current nearest stellar neighbor, Proxima Centauri.
