2012 LZ1

 is an asteroid classified as near-Earth object and potentially hazardous asteroid of the Amor group, approximately 1 km in diameter. It passed within 5.4 million kilometers (14 lunar distances) of Earth on 14 June 2012. It was discovered during the night of 10–11 June 2012 by astronomer Robert H. McNaught and his colleagues using the 0.5-meter Uppsala Southern Schmidt Telescope at the Siding Spring Observatory in Australia, just four days before its closest approach to Earth.

Overview
Arecibo radar observations on 19 June 2012 have shown that is about 1 km in diameter and that  has zero chance of impacting the Earth for at least the next 750 years.

A small change of trajectory caused by Earth's gravity was predicted from the 2012 passby. The Slooh Space Camera streamed live footage of the passby over the Internet. McNaught and Astronomy magazine columnist Bob Berman hosted the broadcast. "We love it when stuff like this happens, because it's fun to do and the public appreciates it", said Slooh president Patrick Paolucci. The asteroid was the same brightness as a 13th-magnitude star, too faint to be seen by the naked eye or a low-end telescope.

The next passby for was 27 July 2016 at 0.5 AU from Earth.
