== 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 is available by adding <code>&view=OPC</code> to the [[query string]] at the end of the body's [[URL]]. Close approach data useused to be available by adding <code>;cad=1</code> or <code>&cad=1</code> to the query string. 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.
