OUMUAMUA EXPLORER from the Hawaiian 'ou meaning 'to reach to', and 'mua', reduplicated to give it emphasis first, 'in front of', and reflects the way the object is like an explorer or messenger sent from the distant past to reach humanity. Roughly it means 'first distant messenger'. The first character is a Hawaiian okina, not an apostrophe, and is pronounced as a glottal stop; the Pan-STARRS team chose it in consultation with the University of Hawaii. OUMUAMUA is the first object from outside our solar system that comes to visit us in 2017 and that, initially, was thought to be the product of extrasolar intelligence due to the fact of not having a coma, but later it was discarded. It is reddish in color as are objects outside the solar system and is between 35 and 167 meters.
