Scholz’s Star (WISE designation WISE 0720−0846 or fully WISE J072003.20−084651.2) is a dim binary stellar system about 17–23 light-years (5.1–7.2 parsecs) from the Sun in the southern constellation Monoceros near the galactic plane. It was discovered in 2013 by astronomer Ralf-Dieter Scholz. In 2015, Eric Mamajek and collaborators reported the system passed through the solar system’s Oort cloud roughly 70,000 years ago, and dubbed it Scholz’s Star. — Wikipedia

Scientists widely accept that the extinction of the dinosaurs was triggered when a massive object smashed into Earth and touched off a global ice age that wiped out as many as three-quarters of all species. The question, however, is where that object originated.
