Asteroid won't hit Earth – but it will get close

March 2, 2016

The asteroid 2013 TX68 will come fairly close to Earth in early March, but the exact time and distance of its closest approach will not be known until after the fact. Sean Marshall, a fifth-year Cornell University PhD student, works on observations of near-Earth asteroids. He says the closest approach could be within Earth's 'ring' of geostationary satellites, or as far out as forty times the distance to the Moon.

Marshall says, "2013 TX68 is estimated to be about 100 feet in diameter. Its closest approach could be within Earth's 'ring' of geostationary satellites, or it could be forty times the distance to the Moon - or anywhere in between.

"Should this asteroid come closer than the geostationary satellites, it would be a rare occurrence – that only happens about once per decade for large asteroids. What we know for sure is that it will not collide with Earth this month, so do not panic."

"The large uncertainty in TX68's orbit makes it difficult to plan observations in advance, but hopefully it will be seen by some of the automated survey telescopes. However, it is possible that TX68 will be so far from Earth that it will be too faint to be seen. If TX68 is detected this month, that would greatly reduce the uncertainty in its and allow astronomers to calculate its future trajectory much more accurately."

1/3 the size of Tungusta impactor so possibly no reaction either electrically or via resonance. Wonder if Mayak launch will be inspecting this fly by of Tx68.

Erm...have you had a look at the Mayak satelilte? Obviously not.

Why don't you at least look up what something like Mayak even is (or when it gets launched) before using it in a post?

As We can now know the Truth, small to medium size (city killer) asteroids can not be tracked or path predicted with ground telescopes/and or radar. The signal to noise ratio is too great to overcome even with giant optics. This Must be done done in orbit.and it must be done with single crystal silicon optics.
The only guarantee that NASA or ESA can give is that We Can't know
