== Close-approach data ==
As of August 2013 (planetary [[ephemeris]] [[Jet Propulsion Laboratory Development Ephemeris|DE431]]) close-approach data is available for the major planets and the 16 most massive asteroids. Close approach data iswas available by adding <code>;cad=1</code> or <code>&cad=1</code> to the [[query string]] at the end of the body's [[URL]].<ref>{{cite web|url=https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2017U1;cad=1|title=JPL Small-Body Database Browser - 'Oumuamua (A/2017 U1)|access-date=June 15, 2018}}</ref> The [[Wayback Machine]] prefers the <code>&cad=1</code> option. The JPL Small-Body Database close approach table lists a [[Linearity|linearized]] uncertainty. The time of close approach uncertainty and min/max distance correspond to the [[3-sigma]] level.
