Astronomers recently discovered that Scholz's star passed close to the Sun 70,000 years ago. Wouldn't its gravity have sent Oort Cloud comets raining into the inner planets?

Scholz's Star and its companion brown dwarf likely passed within the outer reaches of the Sun's Oort Cloud, but scientists don't believe the encounter would have sent comets shooting into the solar system.

Based on the number of long-period comets that enter the inner solar system, astronomers estimate there are probably trillions of them in the Oort Cloud.
