Gliese 710 or HIP 89825 is an orange 0. 6 M☉ star in the constellation Serpens Cauda. It is projected with a reasonable probability to have a close encounter with the Sun within the next 15 million years. The predicted minimum distance is 1. 281 million years from now, possibly approaching as close as 0. 0676 parsecs, 0. 221 light years or about 13,300 AU: being about 20 times closer than the current distance of Proxima Centauri. It will then reach a similar brightness to the brightest planets, perhaps reaching an apparent visual magnitude of about −2. 7 (brighter than Mars at opposition). Maximum total proper motion will peak around one arc minute per year, whose apparent motion will be able to be noticed over a human lifespan.
