I ran into the article below about Earth's temporary moons
while trying to find more about this asteroid. One of the
temporary moons, 200 meters in diameter, is thought to have
been in orbit around the earth for the last 500 years so far.

and here's something on the crater under Antarctic ice that
might have triggered the greatest of all the great extinctions,
the Permian extinction, 250 million years ago. The article
may be gone soon, judging from the brevity of the URL.

This asteroid seems to be about the size that a telescope nearby on
Maui is attempting to detect. But perhaps the scope's main job really
is to look for something coming from North Korea?


We know about all the really big ones that are in stable
earth-crossing orbits, but even little ones can do a lot of
damage. And what about something that just got knocked
out of the Asteroid or Kuiper Belts or Oort cloud and is
heading toward us for the first time? Earth is a tiny target
compared to Jupiter, but nevertheless, that plume and
earth-sized cloud of disturbance on Jupiter after it was
hit by a big comet a few years back does give one
something to think about.

I found a list of the big Kuiper Belt objects found so
far. One of them seems to be bigger than pluto.

Larger still than Pluto and the newly discovered Kuiper
Belt object is Neptune's moon Triton, whose orbit
around Neptune is anomalously retrograde, inclined far
from the usual plane of the planets and large moons
in the solar system, and in an unstable orbit which is
spiraling toward Neptune such that it will collide with
the planet on a time scale very short compared to the
time scale of the solar system. Many people suspect
that Triton is a captured Kuiper Belt object.
