Two Asteroids Buzz Earth in One Two Punch - They will Pass Extremely near our Planet

Two Asteroids Buzz Earth in One Two Punch - They will Pass Extremely near our Planet, at 0.1 and 1.0 LD.

Asteroid 2017 BH30 is Set to Pass extremely close to Earth Jan. 30. The space rock was first observed by Catalina Sky Survey on 2017-01-29. It will fly by Earth on Jan. 30 at 0.1 times the distance to the Moon at a speed (relative to the Earth) of 15.6 km/s. It is estimated to be 4.6 m - 10 meters in size.

Condition code of 6. http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2017%20BH30;orb=1

Another newly discovered asteroid is going to pass close to Earth on Jan. 31. Asteroid 2017 BJ30 was first observed on Jan. 29 and it will fly by Earth on Jan. 31 at 1.0 times the distance to the moon at a speed (relative to the Earth) of 22,210 km per hour. It is estimated to be 13 - 28 meters in size. http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2017%20BJ30;orb=1

Some of them are passing undetected. A small asteroid (7-16 m) made a close approach at 1.1 times the distance to the moon on Jan. 26. 2017

BA7 passed at a speed (relative to the Earth) of 11 km/s. http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2017%20BA7;orb=1
