Derivatives

planetology

noun planɪˈtɒlədʒiˌplænəˈtɑlədʒi

mass noun

The branch of science that deals with planets.
If, however, the human race has now reached the technical capability to carry on some of its industrial activities in space, we should indulge in the mental exercise of ‘comparative planetology.’
Example sentencesExamples
- Many characteristics of the Earth are quite unique, and recent discoveries under-scoring this are causing a turn toward viewing planetology as a study of contrasts with Earth, not similarities to it.
- He criticized the commission for coming up with a set of goals for the exploration program that included topics such as studies of the Big Bang and comparative planetology but omitted a clear statement about searching for life on Mars.

Origin

Middle English: from Old French planete, from late Latin planeta, planetes, from Greek planētēs 'wanderer, planet', from planan 'wander'.

Early Greek astronomers observed certain heavenly bodies moving around the night sky in contrast to the stars, which stayed permanently in a fixed position in relation to one another. This is why they are called planets, from Greek planētēs ‘wanderer’. The Sun and the Moon were once thought of as planets too. Plankton, the term for small and microscopic organisms floating in the sea, comes via German from the related Greek word planktos, ‘wandering or drifting’. See also aeroplane
