During its closest approach at 8 p.m. ET Thursday Slooh will attempt to track newly discovered near-Earth Asteroid 2012 LZ1 as it makes its close approach to Earth. 2012 LZ1 is over 1,600 feet (500-meter) wide about the size of a city block and about 14 Moon (3.3 million miles or 5.3 million kilometers) distances from Earth. The asteroid was never close enough to threaten Earth

On June 5th, 2012, Venus will pass across the face of the sun, producing a silhouette that no one alive today will likely see again.
Transits of Venus are very rare, coming in pairs separated by more than a hundred years. This June’s transit, the bookend of a 2004-2012 pair, won’t be repeated until the year 2117. Fortunately, the event is widely visible. Observers on seven continents, even a sliver of Antarctica, will be in position to see it.
The nearly 7-hour transit begins at 3:09 pm Pacific Daylight Time (22:09 UT) on June 5th. The timing favors observers in the mid-Pacific where the sun is high overhead during the crossing. In the USA, the transit will be at its best around sunset. That’s good, too. Creative photographers will have a field day imaging the swollen red sun “punctured” by the circular disk of Venus.
