Extended Data Table 1: Orbital elements of ‘Oumuamua determined from observations on 2017 October 14–30

From: A brief visit from a red and extremely elongated interstellar asteroid

Table 1
  1. The elements were integrated backwards in time until ‘Oumuamua was 1,000 au from the Sun to remove any possible effects from close encounters during the incoming trajectory. The time-of-passage at pericentre (T) should be interpreted as the peribarion in this case. The elements were computed using the software Find_Orb by Bill Gray.
  2. †The barycentric elements account for periodic terms connected with the motion of the Sun around the barycentre.
