Apollo Class Asteroid Will Have a ‘Near Miss’ Trajectory Past Earth Tomorrow

asteroid


Tomorrow night an asteroid about 100 feet across will make an extremely close approach with Earth as it passes between the planet and the moon.


At 21:07 GMT (16:07 EST), the 98ft (30 meter) asteroid will make its closest approach reaching a minimum distance of less than 217,000 miles (350,000 km), or 0.9 lunar distances.


Scientists claim it will avoid a collision with Earth, but the 33,000 mph (14.85 km/s) asteroid will provide spectacular views for anyone with a good telescope in their back yard.


The Virtual Telescope Project and Slooh will be providing a live online event sharing real-time images of the asteroid named 2014 DX110.



The event in Siberia, at Tunguska, and last years event at Chelybinsk reminds us that asteroids and meteors can cause damage at the surface, even if they don’t actually hit.


‘But the on-going threat, and the fact that biosphere-altering events remain a real if small annual possibility, suggests that discovering and tracking all near Earth objects, as well as setting up contingency plans for deflecting them on short notice should the need arise, would be a wise use of resources.’ - Astronomer Bob Berman



2014 DX110 is an Apollo class asteroid which means it has an Earth-crossing orbit.


There are currently 240 known Apollos, but it is believed that there are at least 2000 Earth-crossers with diameters of 1 km or larger.


If it hit Earth, an impacting Apollo asteroid would make a crater about 10-20 times its size.

United Nations to Adopt Asteroid Defense Plan

The Hollywood adaptation of this story is no doubt already in the works. In the meantime, Scientific American has the details of the UN’s plan to defeat an asteroid attack:


When a meteor exploded over Chelyabinsk, Russia in February, the world’s space agencies found out along with the rest of us, on Twitter and YouTube. That, says former astronaut Ed Lu, is unacceptable—and the United Nations agrees. Last week the General Assembly approved a set of measures that Lu and other astronauts have recommended to protect the planet from the dangers of rogue asteroids.


The U.N. plans to set up an “International Asteroid Warning Group” for member nations to share information about potentially hazardous space rocks. If astronomers detect an asteroid that poses a threat to Earth, the U.N.’s Committee on the Peaceful Uses of Outer Space will help coordinate a mission to launch a spacecraft to slam into the object and deflect it from its collision course.

Happening Now: An Asteroid And Its Moon Sail Past Earth


The pair will come their closest at 4:59 pm ET today.

An asteroid is sailing past Earth today, and it’s bringing along some luggage.


At 4:59 pm ET, asteroid 1998 QE2 will be a mere 3.6 million miles away from our home planet. And it’s not alone. It is bringing with it a moon that orbits it as it flies along its own path.


Okay, “mere” is an exaggeration. It will come to about a distance that’s 15 times the distance between the Earth and the moon. The asteroid is not a threat to Earth, NASA says.


Astronomers first discovered 1998 QE2 in 1998, hence its name. They only discovered that it had an orbiting moon on May 29, however, when radar images showed the moon as a smudge by its side. Among asteroids near Earth, only 16 percent that are 200 meters (655 feet) in diameter or larger are made up of two or three pieces that travel in tandem, called binary or triple asteroids. The new radar images suggest 1998 QE2 is 1.7 miles in diameter. Its moon is 2,000 feet wide.


The pair will not get this close to Earth again for another 200 years.


Over the next week, astronomers using the Deep Space Network antenna in Goldstone, California, and the Arecibo Observatory in Puerto Rico will observe 1998 QE2 as it comes by. Radar helps astronomers discern asteroids’ shapes, rotation, surface features and orbits. Such observations are a part of NASA’s larger effort to learn about asteroids so it can predict when any do threaten Earth–although, of course, we’re not always the greatest at that quite yet.
