When does 2006 SU49 pass Earth?
2006 SU49: closest approach January 2029
2006 SU49 passes Earth on January 28, 2029 at 04:23 UTC, 1,225,433 km from Earth's centre (3.2 lunar distances).
Distance through the flyby
lunar distances, ±12 h (JPL Horizons)Can you see it?
JPL Horizons gives a brightest apparent magnitude of 15.0 as seen from Earth's centre, at 16:24 UTC on Jan 27, 2029: faint: only for large telescopes. At closest approach it is overhead at about 30°S, 162°E, where the Sun is up or in twilight. Seen from the ground, its position and brightness differ from the geocentric values, the more so the closer it comes.
Impact risk
2006 SU49 was on JPL's Sentry impact-monitoring list until 2006-11-23, when further observations ruled out any impact in the period Sentry covers (about 100 years).

Every close approach, 1900–2200
All passes within 0.2 au (78 lunar distances) computed by JPL. None comes closer than the 2029 pass. The uncertainty column is JPL's 3-sigma timing uncertainty; it grows for dates far from today.
