Asteroid to miss – this time around

stronomers have ruled out an Earth impact from asteroid 2002 NT7 on 1 February 2019 – but they say, as yet, future collisions have not been completely excluded. 2002 NT7, a two-kilometre-wide (1.4 miles) chunk of rock, was discovered on 9 July. Initial estimates of its orbit suggested there was a small chance of it colliding with our planet in 17 years’ time. However, the latest observations accumulated over the last few days have confirmed the asteroid will fly harmlessly by.
