‘Rogue’ star won’t collide with our solar system in 29,000 years after all

The solar system of the far future is safe from a run-in with a runaway dead star.

Last year, researchers looked at the trajectory of a rogue white dwarf star called WD 0810–353 with the Gaia space telescope and predicted that it was due for an encounter with our solar system in around 29,000 years. While this may seem a long time in human terms, it is a relatively short period cosmically speaking. For instance, the sun won’t run out of hydrogen and swell out as a red giant for another 5 billion years, destroying Earth and the inner planets in the process.
