• The star’s trajectory suggests that 70,000 years ago it passed roughly 52,000 astronomical units away (or about 0.8 light years, which equals 8 trillion kilometers, or 5 trillion miles). This is astronomically close; our closest neighbor star Proxima Centauri is 4.2 light years distant.
  • Scholz’s star had an unusual mix of characteristics: despite being fairly close (“only” 20 light years away), it showed very slow tangential motion, that is, motion across the sky.
  • While the close flyby of Scholz’s star likely had little impact on the Oort Cloud, Mamajek points out that “other dynamically important Oort Cloud perturbers may be lurking among nearby stars.”
