h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Hello!

I notice you contributed to Master B's ambitious 'We Didn't Start the Fire' project. Myself, I am trying to get a collaborative entry written all about the year 2003 - at A2657865, and I thought that perhaps you might be interested. You'll find a list of major 2003 events on A2657865, some of which you may like to write about, or you may have thought of another event that I forgot about and you may like to write about that instead.

The entry is being written 'collaboratively' in an experimental fashion, and has been hitherto largely ignored. Details about these collaborative methods are at U717892.

With your brain being the size of a small moon, I figured you might at least raise an eyebrow at what is going on there. It's entirely up to you, of course.

Hiya BB:

The project sounds intriguing. I'll be happy to check out the 2003 program.

How big is a small moon, you ask?
Hmmm, I had never been asked to explain that. Frankly, I wasn't certain that anybody, but I, bothered to read PSs.

Well, our moon is pretty massive among its siblings in the solar system. It's the 14th largest body, in radius (1,738 km), of the entire system; larger than Pluto (1,160 km), smaller than the four largest moons (starting with Ganymede at 2,531 km).

I guess that doesn't sound like much, in light of the fact that the Sun contains something like 99.86% of the mass in the solar system. Still, this planetary system's moons run all the way down to 6 km (Deimos; orbiting Mars).

A lot of 'moons' look to be more like asteroids that got caught in a planet's gravity, on their way to a vacation on the Sun. The tiny moons run fom about 6 km to 18 km. The smallest of the remainder is, I believe, Triton; but that is still larger than Pluto (Darn that rock, it screws up everything by insisting it is a planet!).

The larger moons run from 2,575 to 2,631; the medium moons from 1,738 to 2,400; and the small moons from 1,353 to 1,569.

I guess it would be in there, someplace.

Thank you, and thank you.

Why, of course I read personal spaces! I find it most interesting the variety of ways that researchers choose to introduce themselves...
