    October 12th, 2017

    Some are predicting a worse-case-scenario of Asteroid "2012 TC4" exceeding 470 kilotons, if decides it really wants to meet us on October 12th. Others put it's proximity at around 8 thousand miles (approx 13,000 kms). It's size is thought to be the size of a house and said to be twice that of the Chelyabinsk meteor of 15th February 2013, which came in at around 40,000 mph.

    Nobody is really certain of it's size or closest approach, only estimates exist, but those guesses place that 'pass' well within the orbits of geostationary satellites (which I think from memory is around 33,000 miles, excluding LaGrange points).

    Minimum Orbit Intersection Distance (MOID) is 0.079 LD.

    The European Space Agency's head of Near Earth Object monitoring gives it a one-in-a-million chance of hitting us.

    If it's made of iron it will be worse than if it is made of rock because the density of the atmosphere and heat of entry will often cause rocks to break up whereas it causes iron to heat up.

    3 space agencies are predicting a near miss.
