Asteroid passed close to Earth on Thursday, posed no risk of impact

GETTYAsteroid 2012 T4C is set to fly past Earth

On October 12, a small asteroid came within 26,000 miles of Earth.

There was no actual risk of a hit, although the asteroid did come well inside the orbit of the Moon and that of some human-made satellites.

Among the telescopes that were involved is the big radar dish at NASA's Goldstone Deep Space Communications Complex in the California desert, whose observations should help scientists nail down 2012 TC4's size, Chodas said.

Mike Kelly, who leads the agency's project to track it, said: "We've now been observing TC4 for two months, so we have very accurate position information on it, which in turn allows very precise calculations of its orbit".

No known asteroid is now predicted to impact earth for the next 100 years. This asteroid is approximately house sized, is known as 2012 TC4, and will offer the chance to scientists to prepare for a less fortunate scenario, when another space object might actually threaten our planet with an imminent clash.

That represents about an eighth of the distance between the Earth and the Moon. Meaning every step like initial and follow-up observations were going to be done in addition to orbit determination efforts and global communication between all the researchers worldwide taking part.

Paul Chodas, manager of the Center for Near-Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory, told Newsweek, "When monitoring an asteroid on a collision course with Earth, we would want to know these things to assess the impact site and potential damage". It wil likely return in 2050 and 2079 as it continually loops around the sun.

Scientists found this asteroid about five years ago when it had been at the twice the current distance away from the Earth before disappearing view.

The closest approach to Earth occurred over Antarctica at about 1:40 a.m. It has been described as a dress-rehearsal in case a similar asteroid hits the Earth.

But even if we become better at predicting a strike, there is very little we can do about it. TC4 is the 13th object in space that poses a threat to hit the Earth, the Guardian wrote.
