‘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.…
