Navigate to the 'Close Approaches' page by clicking the 'Close Approaches' link in the main navigation (ID 64). On the 'Close Approaches' page, identify the most recent close approach event (top of the list) and extract its nominal close approach distance in Lunar Distances (LD). State the definition of a NEO and the closest approach distance for the most recent event.
The agent successfully navigates to the 'NEO Basics' page. The agent states the definition of a Near-Earth Object (NEO) as 'an asteroid or comet whose orbit brings it within 1.3 astronomical units (AU) of the Sun and therefore within approximately 0.3 AU (about 45 million kilometers or 28 million miles) of Earth’s orbit'. The agent successfully navigates to the 'Close Approaches' page. The agent identifies the most recent close approach event. The agent states the nominal close approach distance for the most recent event in Lunar Distances (LD).
