Encyclopedic overview
Gliese 710, or HIP 89825, is an orangish 0.6 M☉ star in the constellation Serpens Cauda. It is projected to pass near the Sun in about 1.29 million years at a predicted minimum distance of 0.051 parsecs – 0.1663 light-years (10,520 astronomical units; 1.573 trillion kilometres) – about 1/25 of the current distance to Proxima Centauri. Such a distance would make for a similar brightness to the brightest planets, optimally reaching an apparent visual magnitude of about −2.7. The star's proper motion will peak around one arcminute per year, a rate of apparent motion that would be noticeable over a human lifespan. This is a timeframe, based on data from Data Release 3 from the Gaia spacecraft, well within the parameters of current models which cover the next 15 million years.
