Yet Another Asteroid Visits Earth

Asteroid 2005 YU55 is scheduled to pass within approximately 201,700 miles of the Earth on November 8, closer than the Moon’s orbit but further away than many other recent asteroid passes. However, 2005 YU55 is 1,300 feet across, making it the largest asteroid to pass the Earth since 1976, although it doesn’t pose any danger. The next known large asteroid to pass near Earth won’t happen until 2028.

Asteroid Flies by Earth

A 7 meter long asteroid, 2009 BD, passed within 346,000 kilometers of the Earth on June 2, coming inside the Moon’s orbit. Because 2009 BD is a co-orbital object, it will remain relatively close to the Earth for the next month or so, generally about 3,850,000 km away.

Visit from a Small Planet

A small asteroid (2011 CQ1) discovered on February 3, passed around 7,500 miles from Earth on February 4 at 19:40 UT. This is about a quarter of the distance that 2010 TD54 passed by the Earth in October. 2011 CQ1 is between 1 and 2 metres across, making it smaller than a standard sofa. Had the asteroid hit Earth, it would have vaporized in the atmosphere.

Asteroid Buzzes Earth

A small asteroid (2010 TD54) passed around 28,000 miles from Earth on October 12, slightly higher than satellites in geosynchronous orbit. The asteroid, which was only about 6 meters in diameter, passed over Singapore around 6:50 EDT. Had the asteroid hit Earth, it would have vaporized in the atmosphere.

Asteroids Visit Earth

Asteroid 2010 RX30 passed within 154,000 miles of Earth at 5:51am ET on September 8. Approximately twelve hours later, at 5:12pm ET, asteroid 2010 RF12 is expected to pass within 49,088 miles of Earth. The asteroids are both estimated to be less than 70 feet in diameter and neither poses a threat to Earth. For comparison, the Moon is approximately 238,857 miles away.
