Say hello to 2013 YP139 — a newly discovered 0.4 mile (650 meter) wide asteroid spotted by NASA's recently re-started NEOWISE spacecraft. Preliminary calculations show it'll come within 300,000 miles from Earth — thus qualifying it as a potential headache
In astronomy, a lunar distance (LD) is a measurement of the distance from the Earth to the Moon. The average distance from Earth to the Moon is 384,400 km (238,900 mi).
It could swing by at a distance closer than the Earth is to the Moon, but it won't do so within the next century.
Not to be a pain - but you've put 650 KM in your first part. Almost gave me a heart attack until I kept reading!
Do you know If we will see it? It is very dark like coal but as it gets closer will we see it?.
Well I suppose if we don't get hit now, we'll get hit eventually. I'm a glass half full kinda guy.
Do we have an ATS bookie to take bets?
