Extended Data Fig. 1: Non-gravitational accelerations of Solar System comets and ‘Oumuamua.
From: Non-gravitational acceleration in the trajectory of 1I/2017 U1 (‘Oumuamua)
Measured non-gravitational radial accelerations A1 for short-period (red) and long-period (blue) comets from the JPL Small Body Database (https://ssd.jpl.nasa.gov/sbdb.cgi). The solid vertical black line indicates the A1 value for ‘Oumuamua, which falls within the range observed for Solar System comets; the dashed vertical black lines mark the corresponding 1σ uncertainty.
