For a start, there's this thing here:
That tellurian (it's sometimes spelled tellurion) was made in 1766 to demonstrate the motion of the moon and the earth in space.
Then of course there are the Star Trek Tellurians, an alien species known, rather endearingly, for their mint truffles.
There are tellurians all over Dr Who, too: in fact there's at least one tellurian in the large majority of the episodes. This being the case, it's a good job the Time Lord knows what a tellurian actually is.
And that's what? Well, a tellurian is anything relating to, and especially an inhabitant of, the planet Earth.
Yes, so that probably means you, that's right.
A tellurian...you know, it makes me feel quite dashing and cool. Almost (but fortunately not quite) cool enough to get myself a skin-tight playsuit in some gleaming metallic fabric and some silver killer heels.
Mind you, I wouldn't say no to a mint truffle, either.
Spot the frippet: tellurian. This word comes from the Latin tellūs, the earth.
