First-ever interstellar object named as 'Oumuamua
The first known object to visit our Solar System from another star system has been given the name, 'Oumuamua, which means "a messenger from afar arriving first" in Hawaiian. Earlier referred as A/2017 U1, the 400-metre-wide "asteroid or comet" was discovered by the Pan-STARRS1 telescope on Hawaii's Haleakala volcano. 'Oumuamua zoomed past the Earth at over 90,000 kmph in mid-October.
