The asteroid dubbed 2017 Fu102 was first observed on March 29th. It is flying by as I write this, at roughly half a Lunar Distance (LD) form Earth. It’s the 14th sub-Lunar Distance object to flyby the Earth since the beginning of the year.
On April 3rd, another object named 2017 FT102 will flyby at 1 LD.
There is no danger but what’s a bit worrisome is that these objects weren’t discovered until 4 days before near-Earth flyby.
