NASA has just announced that a space asteroid is coming very close to Earth later on today, but according to their calculations does not pose any risk of collision with Earth or the Moon. The space rock, an asteroid with an approximate size comparable to Comino will pass close to Earth later on today.
Radar images were taken of the asteroid on April 18, 2017 by the Goldstone Solar System Radar. The asteroid is to make a close flyby of Earth on April 19, 2017, and at its closest approach on that date it will come within 1.8 million kilometers (1.1 million miles) of the planet. It’s projected to reach an apparent magnitude of 11 or 10, which should put it in the observable range of 8 inch telescopes from a dark location.
The huge asteroid is travelling at 33 metres per second it reminds us all that the universe is a very dynamic and potentially dangerous. The asteroid will remain visible in the sky for the next few days before it fades away into the oblivion.
The Asteroid which is being called 2014-JO25 will be the largest asteroid which will come this close to Earth since 2004.
A collision between the Earth and an approximately 10-kilometre-wide object 66 million years ago is thought to have produced the Chicxulub Crater and the Cretaceous–Paleogene extinction event, widely held responsible for the extinction of the dinosaurs.
While the chances of a major collision are not great in the near term, there is a high probability that one will happen eventually unless defensive actions are taken. Recent astronomical events—such as the Shoemaker-Levy 9 impacts on Jupiter and the 2013 Chelyabinsk meteor along with the growing number of objects on the Sentry Risk Table—have drawn renewed attention to such threats. NASA warns that the earth is unprepared.
Most deflection efforts for a large object require from a year to decades of warning, allowing time to prepare and carry out a collision avoidance project, as no known planetary defense hardware has yet been developed.
