According to the data collected by the CNEOS, it's possible that 2016 NO56 will approach Earth within a lunar distance of only one, which is equivalent to 0.00258 astronomical units or roughly 240,000 miles.
This is more than 13 times the distance between Earth and Moon (13 lunar distance or LD) and is totally safe for Earthlings.
It would seem that in any given era there will always be some eclipses occurring at both extremes of lunar distance. The same conclusion can be drawn from the diagram about solar distances.
Since the beginning of this year, 24 other objects have passed by closer than the lunar distance, although the large majority of them were even smaller than the approaching asteroid.
"While near-Earth objects of this size have flown within a lunar distance in the past, we did not have the foreknowledge and technology to take advantage of the opportunity," CBS News quoted Barbara Wilson, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., as saying in a statement.
A 10-meter-sized near-Earth asteroid from the undiscovered population of about 50 million would be expected to pass almost daily within a lunar distance, and one might strike Earth's atmosphere about every 10 years on average.
According to reports from the United Kingdom-based newspaper The Sun, some of these asteroids may come as close as 0.15 lunar distances to Earth-enough to warrant concern from the government body.
Astronomers will closely monitor The Rock as it comes within 4.6 lunar distances from Earth at 1.24pm UK time on Wednesday.
In 2004, the 3.1-mile (5-km) wide asteroid Toutatis passed about four lunar distances, or just under a million miles (1.6 million km) from Earth.
(2) The two major proposals to emerge--astronomical use of lunar distances and mechanical use of timekeepers --were complementary, although they have often been seen as rivals.
In the wake of NASA's recent LADEE mission, which demonstrated the feasibility of laser transmission from lunar distances at data rates high enough to stream movies, NASA is working with the Aerospace Corporation to test a CubeSat version of a similar system by early 2015.
On September 29, 2004, the asteroid zipped by Earth at only 0.01 AU -- about 4 lunar distances.
