Have any of you heard any details about the small asteroid discovered
last week that may make a fairly close approach on February 2, 2019? If
so, could you pass along any info you might have?
I just covered it for New Scientist's web site:
As asteroid searches pick up more objects, we're going to see more of
these stories. When they first spot them, they have only a few days
of data -- 14 in this case -- and the large uncertainty in position
at some times in the future can sometimes allow for a collision -- at
odds of one in 100,000 or 1 in a million. Longer term observations
make these possibilities go away.
The astronomers give proper qualifiers on their warnings, but some of
the press sometimes loses those qualifiers. -- Jeff Hecht
