American Horse
AKA "Mustang"
We have a new one, just discovered, that will pass about 35,000 miles from Earth on the 28th of May, at 14.57 U.T. which I think converts to about 21:00 or 9-PM Eastern time , and it's about 36-meters in diameter.
Its discovery is too recent to have any good data on predicting future orbits.
Linked below is an excellent Video showing it's earth crossing path. It's coming in from the outer solar system and was discovered just a couple of days ago on the 23 May, and coming in from the dark side, which means its face is lit by sunlight making it more easily spotted as it faces the sun.
If it had already swung around the sun and be coming from the bright side we wouldn't be able to have spotted it as easily; five days advance of passage could have been reduced to little to nothing, and it be seen only after it was heading out.
This shows all the approach path relative to earth in a very interesting computer generated projection.
