the three new ones, discovered and announced a day or three back:

https://www.smithsonianmag.com/smart-news/three-near-earth-asteroi= ds-were-hiding-in-the-suns-glare-180981055/

(Atira class are rocks within earth orbit. They are very hard to see,
probably overly baked (low on volatiles), and get bright sun all the
time)

[1] I'm very inspired by DART, but afraid to do the math for this
tonnage and speed. (anyone? there's a LOT of zeroes... ) I have
project ploughshare on my mind, except kinetic, and it's less
deflection on my mind than reducing a rubble pile to rubble,
identifying the good pieces, and bringing them back.
