Slooh will broadcast live telescope views of the near-Earth asteroid, called 1998 OR2, tonight (April 28) beginning at 7 p.m. EDT (2300 GMT). You can watch it live here on Space.com, courtesy of Slooh, or directly from Slooh.com and its YouTube page. This webcast will be free for anyone to watch, but paid members of Slooh can also tune in at Slooh.com and join a so-called "star party" on Zoom, where viewers will be able to join the discussion. Slooh astronomers will also be answering members' questions during this "star party."
The one-hour public event will commence just 11 hours before asteroid 1998 OR2 will make its closest approach to Earth, tomorrow at 5:56 a.m. EDT (0956 GMT). At that time, the asteroid will be about 3.9 million miles (6.3 million kilometers) from Earth, or about 16 times the average distance between Earth and the moon.

It’s the one we won’t see that’ll get us.
“It’s the one we won’t see that’ll 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)?
According to Wikipedia, it has a diameter of roughly 2 km (1.2 miles).
Yawn!!
Regards,
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).”
Good question.
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."
Regards,
The proper term for an object that has “spehricalized” is “hydrostatic equilibrium” FYI.
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.
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?.
DoodleBob might know the answer to that.
Go to https://cneos.jpl.nasa.gov/ca to search for things that may or may not kill us all.
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.
