Traffic Report  on 11 April '12

One object reported inside ten LD

One asteroid is reported moving inside ten lunar distances (LD) of our planet today. Risk-listed 2012 GD exits ten LD, traveling from 9.51 to 10.04 LD. On approach next, 2007 HV4 is calculated to arrive inside ten LD on April 14th (passage uncertainty 1.748 days) and 1992 JD on April 30th (uncertainty 4.600 hours).

This report was generated at 1609 UTC.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Object distances are interpreted by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

The MPC's NEO Confirmation Page has 8 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had eight objects listed. Of these, four were "one nighters."

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
