The first confirmed interstellar visitor to our solar system is a needle-shaped asteroid given the Hawaiian name ‘Oumuamua. Astronomers have determined that ‘Oumuamua made its closest pass by the sun on Sept. 9 and then zoomed within 15 million miles (24 million kilometers) of Earth on October 14. The object is now barreling toward the outer solar system at about 98,400 mph (158,360 km/h) relative to the sun, researchers have said. PBS Space-Time takes a closer look.
