In a 2nd December 2019 article at Phys.org (https://phys.org/news/2019-12-minimoon-fireball.html), Bob Yirka reports on an
interesting finding uncovered by pouring through data from
Australia's Desert Fireball Network.
An extremely slow fireball (codename DN160822_03) with an initial velocity
of around 11.0 km/s was detected by six of the high-resolution digital
fireball observatories located in the South Australian region of the
Desert Fireball Network.
By integrating its orbit, researchers say the object had probably
orbited Earth as a "minimoon" prior to reentry.
