Ordo Hubble
From Wikipedia, the free encyclopedia
Ordo Hubble[1] (Anglice Hubble sequence) est systema classificationis morphologicae ab Eduino Hubble anno 1926 excogitatus et ad galaxias adhibitus.[2][3][4] Praeterea, ordo Anglice per ludibrium Hubble tuning-fork diagram ("descriptio furcae contendendi Hubble") propter formam qua usitate exprimitur saepe appellatur.

Propositum Hubbleanum galaxias ordinarios in tres classes latas dividit—ellipticos, lenticulares, spirales—per eorum aspectum constitutas, primum in laminis photographicis visas. Quaedam autem classis quartum galaxiam continet, quibus est aspectus enormis. Ordo Hubble iam est propositum galaxiarum classificatorum saepissime in professionalibus astronomorum investigationibus et in astronomia idiotarum? adhibitum.
