Gliese 710, also known as HIP 89825, is an orange star with a mass of 0.6 M that resides in the constellation Serpens Cauda.
It is predicted to pass near to the Sun in approximately 1.29 million years, at a minimum distance of 0.1663 light-years (10,520 astronomical units) (around 160 billion kilometers) — roughly one-quarter of the current distance to Proxima Centauri.
At this distance, the brightness would be equivalent to that of the brightest planets, with a magnitude of around 2.7. (brighter than Mars at opposition). The true motion of the star will peak at around one arcminute per year, a rate of apparent motion that is noticeable during a human lifetime.
Based on Gaia DR3 data, this timeline fits comfortably within the parameters of current models, which include the next 15 million years. And since its journey will take it through the Oort cloud, we may anticipate an increase in cometary activity in our solar system.
