This is exactly what NASA should be doing as opposed to muslim outreach.
This one is probably larger than the one that broke up over Chelyabinsk, Russia a few years ago, and a bit smaller than the one that made the crater in Arizona (stated to be 50 meters in diameter).
So it’s prbably about the size that could make a large blast near the surface and possibly a crater, the Chelyabinsk event broke up and did damage mainly through shock waves that broke windows in the region.
If this one veers off course and hits the earth, it would probably do significant damage if it hit a populated area, and make a dramatic explosion with possible shock waves or tsunamis if over open country or the ocean.
I am guessing 20-25 meters is about the lower end of what might really concern us here on earth. Not very big, and not observable from earth until very close to impact.
To give some sense of the scale, I think the Gulf of Mexico dinosaur extinction event involved a 5-10 km wide asteroid. Anything much bigger than 25 km might be a planetary extinction event, but we know where almost all of those bad boys are already, and they are not in earth-crossing orbits.
The asteroid Eros stays between Earth and Mars almost all of its orbital life, never crosses our orbit, and is about 20 km long. But there are few others that big anywhere near the earth. Big asteroids in the main belt range from 100 to 1,000 km; those are mainly in stable orbits beyond Mars.
When members of congress figure out how to enrich their family fortunes from an asteroid impact crisis, it will be done.
Until that happens (which it will, sooner or later), they consider it a yawner.
