Asteroid 2015 TC25 will pass very close to Earth (0.3 LD) on Oct. 13th. http://neo.jpl.nasa.gov/ca/
At the time of closest approach, 2015 TC25 will be approximately one-third the distance from the centre of the Earth to the moon or about 68,069 miles (104,718 km).
From its reflected brightness, astronomers estimated that the asteroid is about 20 feet (7 metres) in size.
2015 TC25 was discovered on Oct. 11th just two days before its closest approach to Earth.
There are also 5 more NEO’s that are going to pass by Earth the next two days (Oct. 12-13).
None of these 6 asteroids could pose any threat to our planet according to NASA.
The average distance to the Moon is 384,403 km (238,857 miles).

Up today (Oct. 12, 2015), 1,618 NEOs have been classified
as Potentially Hazardous Asteroids (PHAs).
Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time. http://spaceweather.com/
