When observed with the unaided eye, Omega Centauri, the object in this image, appears as a fuzzy, faint star. But the blue orb we see here is, in fact, a collection of 10 million stars.



Astronomers using the Nobeyama Radio Obeservatory (NRO) 45-m telescope found that high-density gas, the material for stars, accounts for only 3% of the total mass of gas distributed in the Milky Way. This result provides key information for understanding the unexpectedly low production rate of stars

Dorset where else eh? >>> Thats ENGLAND<<<
just read a couple of news items about this
"came out of Nowhere to cross earths orbit ( a couple of Hours warning)"



Astronomers in Brazil and the United States separately discovered 2019 OK a couple of days ago, but its surprise visit was only announced a couple of hours before it passed by. "The lack of warning shows how quickly potentially dangerous asteroids can sneak up on us," Brown wrote. And though this asteroid "is not a threat to Earth right now," other such near-Earth asteroids can be.

Here's a kicker.

I pointed out many of us are thinking about asteroid(s) hitting earth, but I pointed out what will happen if an asteroid hits the moon. Will it kick the moon out of orbit. I then got an answer that the moon is to big by a user in the thread, & the answer was no. Then what seems like an expert told me the real answer.

If the asteroid has enough mass it will push the moon ever so slightly out of orbit. So it's not the size, it's the mass compared to the moon.

Yes it totally depends on size or composition.

Such an impact would need to be greatly massive. No one would miss such an impact as even if it happened on the far side of the moon, we would still see the results of such an impact within seconds of it taking place. At a maximum of 130m estimated size, even if it were solid gold(which it wasn't), it just isn't massive enough to change the trajectory of the moon in any meaningful way.
