“Its the one we wont see thatll get us.”
They’re shut down most of the observatories because of the Wuhan Cootie Virus. NASA could tell us but they probably wouldn’t.

How massive must an object be to sphericalize (I made that word up)?

As always, no instant mention in the article of the asteroid's size.
According to Wikipedia, it has a diameter of roughly 2 km (1.2 miles).
Yawn!!

To: alexander_busek
From the article:
“While asteroid 1998 OR2 poses no threat to our planet at this time, NASA has classified it as a “potentially hazardous” asteroid due to its large size and the fact that its orbit intersects with Earth’s orbit around the sun. Astronomers have estimated that asteroid 1998 OR2 has a diameter of approximately 1.2 miles (2 km).”

I said
instant mention.
No use burying essential data farther down in the article.
The headline refers to "big asteroid."
Should be retitled "Mile-wide asteroid to come within a million miles of Earth today."

The proper term for an object that has “spehricalized” is “hydrostatic equilibrium” FYI.
To: Little Pig
Okay, thanks LP. So the question would be:
"How large must an object be to reach hydrostatic equilibrium?"Doesn't the word hydrostatic indicate liquidity?

It does indicate liquidity, like the center of our planet is liquid rock. Not sure about the algorithm though because I imagine it depends on the mass. Something that’s very dense won’t need as much mass as something that’s not dense, so they would reach equilibrium at different sizes. The material matters too.
To: Little Pig
I suppose a solid would behave somewhat like a liquid under sufficient, uniform pressure, i.e. gravity of sufficient magnitude, and reconfigure itself into a sphere.

Didn’t NASA say the last large asteroid near miss would hit in 2024 when it completes it’s orbit?.

"Mile-wide asteroid to come within a million miles of Earth today." Bu this headline would be so much more sensational:
"Million-Mile-wide asteroid to come within a mile of Earth today."

Thanks for info but I recall seeing on the science channel about NASA said on is due in 2024 not sure if act but it’s what they were to have said.
