2016 CG18 is a newly discovered asteroid and it will pass very close to us tomorrow (06 Feb), just 0.39 Lunar Distance or 149,916 km / 93,153 miles away. The closest point will occur at 13:29 UTC.
149,000 to 150,000 km is really close in cosmological terms fortunately there isn’t any worries about 2016 CG18 getting any closer for a while. Orbital calculations shown at ESA’s NEODys-2 site show this is the closest approach until at least the year 2100.
The most remarkable thing about the asteroid is that it is only 7 meters across and the Catalina Sky Survey was able to find it on 03 February — that’s really good!

UPDATE: Just learned of another asteroid called 2015 NJ3, this is termed as a “Potentially Hazardous Asteroid”, NOT that is is a danger anytime soon that we know of but one that bears watching. Preliminary data is just out, more to come.
