Two moons would certainly be very cool.
You realize that you’ve just provided an opening (a what?!?) for another stream of Uranus jokes...
I wasn’t trying to make a crack..oh wait..no...
The Big Splash:
A Scientific Discovery

the Origin of Life,
the Water We Drink, the Death of the Dinosaurs,

and the Very Future
of the Earth Itself

Sigwarth and I analyzed over 10,000 images and learned a good deal about the black spots in the process. Our interpretation of the events continued to involve meteor impacts into Earth's upper atmosphere.By counting the spots in our images we were able to estimate the rate at which these objects appeared. This was the simplest measurement to do. We saw ten holes per minute on the daylight side of Earth. So we doubled that figure to obtain the rate of these objects over the entire face of Earth. There had to be about twenty such objects entering the atmosphere every minute. That was an alarming number of objects.
