DOUBLE STAR Meaning and
Definition
-
A double star refers to a celestial object composed of two stars that appear close to each other in the sky, forming a binary star system. The two stars may either be physically connected and orbiting around a common center of mass or simply appear as close pairs from the vantage point of Earth, while being at different distances from us. These pairs can be observed with the naked eye or through telescopes, revealing distinct characteristics and properties.
In the case of physically connected double stars, they are often referred to as binary stars. Binary stars are bound together by gravity, orbiting around each other in a stable dance. The characteristics and behavior of binary stars provide valuable information about their formation, evolution, and the dynamics of stellar systems in general.
Alternatively, visual double stars are pairs that appear close to each other but are not physically connected. They merely lie along our line of sight and may possess vastly different distances from Earth. Visual double stars can still offer insights into stellar properties, such as brightness, color, and temperature.
The study of double stars has contributed significantly to many branches of astrophysics, including stellar evolution, stellar dynamics, and gravity. Observations and analysis of double stars offer astronomers a unique opportunity to explore the intricacies of stellar physics and provide clues about the universe's structure and composition.

Etymology of DOUBLE STAR
The word "double star" is derived from Latin roots.
The term "double" comes from the Latin word "duplus", which means "twofold" or "double". This word was later adopted into Old French as "doble", and eventually became "double" in English.
On the other hand, the word "star" originated from the Old English word "steorra", which in turn came from the Proto-Germanic word "sterrō". This term has cognates in other Germanic languages, such as German "Stern" and Dutch "ster". Ultimately, it can be traced back to the Proto-Indo-European root "*h₂stḗr", meaning "star".
So, when combined, "double star" refers to two stars that appear close together in the sky.
