It’s being called a very close shave, at least in astronomical terms: new research indicates that 70,000 years ago a dim star passed within a mere 8 trillion kilometers (5 trillion miles) of our solar system.

That’s about one-fifth the distance from the solar system to Proxima Centauri, the star that is currently our system’s closest stellar neighbor, and the closest that any star has ever come to our system.

The small red dwarf star was discovered in 2013 by German astronomer Ralf-Dieter Scholz, according to a written statement released by the University of Rochester. A red dwarf with a mass about 8 percent that of the sun, “Scholz’s star” isn’t the most prepossessing star in the cosmos. But when astronomers noticed that the star and its even less massive brown-dwarf companion were moving very slowly across the sky, they took notice.
