The term originated from the Greek verb ἐκλείπω, which meant “to abandon”, “to darken” and “to cease to exist”. The word was first used around the 1570s and is still used in its original form today. In modern day, there are different forms of an Eclipse, including a Lunar and a Solar Eclipse.

Uranus

Current Usage - “the planet which is seventh in order from the sun, directly after Saturn”

History - Uranus was the first planet to be discovered after ancient times when all other planets received their names. Named after the God of heaven, Husband of Gaia. The term originates from the Latin word “Uranus” and the Greek word “Ouranos” which literally means “heaven the sky”. After much debate over the name of the planet, it was coined “Uranus” and the term was not commonly used until around the 1850’s.
