Galactic Taxonomy

I figure that once humans start exploring the galaxy and finding some forms of life, sapient or otherwise, that it will only be a matter of time until binomial nomeclature is applied to those organisms.

Last Friday I posted about the Burgess Shale. One of the main problems with the Burgess organisms is taxonomy. Taxonomists are so reluctant to put them into their own phylums. Instead they become shoe-horned into other groups regardless of how related they are to that group.

I figure that once a new planet or system with life is discovered, they will try to categorize these organisms under the groups currently set up for Earth-based life, even though it is almost certainly going to be different to life on Earth. My worrying is not very substantial though, as i'm sure, that as professionals, they will have their own ideas on how to confront this situation.

I propose the following template for a taxonomic system that goes up to the level of "System":

>System
>>Planet
>>>Domain
>>>>Kingdom
>>>>>Phylum
>>>>>>Class
>>>>>>>Order
>>>>>>>>Family
>>>>>>>>>Genus
>>>>>>>>>>Species

So as an example, the simplified taxonomy of humans:

>System - Solar
>>Planet - Terran
>>>Domain - Eukaryota
>>>>Phylum - Chordata
>>>>>Class - Mammalia
>>>>>>Order - Primates
>>>>>>>Family - Hominidae
>>>>>>>>Genus - Homo
>>>>>>>>>Species - Homo sapiens

As for the problem of life being found on meteorites or asteroids. Under the planet level they could be notarized as "Intrasolar Body [1P/Halley]" for example.
