The object zipped into our solar system and passed the sun at an
incredible 16 miles per second. It was shiny, reddish in hue, oblong,
between 300 and 3,000 feet long, and between those dimensions. It was
already leaving our system when Canadian astronomer Robert Weryk
discovered the object during a telescope scan in October 2017.
This mysterious item, which they called "'Oumuamua," perplexed
astronomers. Hawaiian for "scout" is that. Nobody was certain of what
'Omuamua is or isn't.
