Dr David Whitehouse mentioned the measure could possibly be taken towards an area rock the scale of a soccer pitch which is being monitored by the European House Company (ESA) and will strike the planet in slightly over seven years.
The asteroid, known as 2024 YR4 and measuring 100m by 40m, is at present at a distance of round 27 million miles and is edging away.
Nevertheless, its path will cross our orbit on 22 December 2032 and was initially estimated to have a one in 83 probability of a direct hit.

He added: “I think this has the potential to be very serious indeed.”
Compared, the astronomer mentioned the prospect of successful the lottery was one in 14 million.
“So, we have to keep a close eye on this object because it could turn out to be the most dangerous thing in space,” he added.

Dr Whitehouse defined the “orbit will be refined” which is able to most probably result in a decrease chance, however specialists solely have a “couple of months” to watch the asteroid earlier than it disappears out of sight till 2028.
He mentioned: “And that’s the time we will have to take measures to deflect it. So, we’ve got some very serious decisions to make. We cannot ignore this rock.
“It is the best chance of an impression I can recall. And it has the potential, the chance for being an emergency for planet Earth.”
The House Mission Planning Advisory Group, which is chaired by the ESA, will focus on the newest observations of the asteroid at a gathering in Vienna subsequent week.
If the impression danger is confirmed it’ll make official suggestions to the United Nations and work could start on choices for a “spacecraft-based response to the potential hazard”, the company mentioned in an announcement.
Dr Whitehouse mentioned emergency deflection measures could must be thought-about, together with reaching the rock in 2028 in an try to nudge it “slightly out of its orbit” in order that 4 years later it misses Earth.
Simply over two years in the past, NASA smashed a spacecraft into the 160m-wide asteroid Dimorphos and efficiently modified its orbit.
Dr Whitehouse mentioned: “We might even have to consider the severe measures of sending up a nuclear weapon to the surface of this asteroid in order to deflect it further.”
On common, the Earth takes a direct hit from an asteroid of an identical dimension as soon as each few thousand years.
In 1908, a barely smaller asteroid – thought to have measured 60m throughout – exploded over Siberia. It flattened 80 million bushes over an space of 830 sq. miles.
Dr Whitehouse mentioned: “I can’t stress strongly enough that this is a threat that’s not a bit of astro fun, that’s not a bit of ‘gosh, isn’t it amazing?’
“This truly may develop into a severe risk to our planet.”
