The official name of the object is 1l/2017 which was given by IAU(International Astronomical Union).  In addition to the technical name the Pan-STARRS team dubbed it as 'Oumuamua' which is Hawailan for "a messenger from a far arriving first" Two of NASA's space telescopes Hubble and Spitzer tracked the object travelling about 85,700 miles per hour relative to the Sun.  Also other Telescopes in ground level continue to track the object.

Today Oumuamua is somewhere between the orbits of Saturn and Neptune and is going far away from us.
