JPL Small-Body Database: 'Oumuamua (A/2017 U1), orbit solution 16
Jet Propulsion Laboratory Solar System Dynamics, 2018. NASA JPL Small-Body Database.
JPL's orbit solution 16 by Davide Farnocchia (26 June 2018) from 207 observations: eccentricity 1.2011, perihelion 0.2559 au, inclination 122.74 degrees, perihelion passage 9 September 2017, with fitted non-gravitational parameters A1, A2 and A3 in a Marsden-style model. Also served by the Horizons system.
What it's used for here
