Discussing Gliese 710's 86% Chance of Hitting the Solar System
Mar 15, 2010 · Based on proper motion and more recent radial velocity data from the HIPPARCOS space satellite mission, Gliese 710 is expected to come within 1.1 light-years (0.34 pc) of Sol in less than 1.4 million years, but astronomers do not expect it to "perturb the Solar System's Oort Cloud sufficiently to create a substantial increase in the long-period comet flux …
Where Are the To-Scale Diagrams of Alpha Centauri's Orbits?
Dec 1, 2022 · The period must be close to a million years. That's comparable to the motion of the "external" stars - for example, Gliese 710 will become the closest star to the sun in about a million years. The present orbit has almost certainly been perturbed by other stars, and it will continue to be perturbed in the future.

Sep 24, 2018 · Gliese 710 is supposed to come within a quarter of a light year 1,280,000 years from now. Scholz' star came within a lightyear 70,000 years ago. Over a few million years most stars should have encounters much less than a light year. The direction is random.
Closest Habitable Planet: Gliese 581g | 79 Year Trip? - Physics …
Feb 23, 2012 · The 5.87 trillion miles ryan mentioned is for one light year, so the journey to gliese 581g at 11m/s will take about 340,000 years. The planet is about 3-4 Earth masses and its diameter is estimated at 1.2 - 1.4 times that of earth. That gives it a mean density somewhat greater than earth, so it definitely looks like a rocky planet.
