I wonder when a star will get really close to the Sun, like 1 or 2 light years?

Gliese 710 is heading almost directly towards the Sun and will pass about 1/6 light year from the Sun in about 1.29 million years. The Hipparcos mission got accurate enough data to show Gl 710 will get close, but Gaia refined the figures significantly in the last few years.

Spectral type K7 V, so not a red dwarf, but also well below solar luminosity. Still more than massive enough to do…umm, fun things to the Oort Cloud.
