I'm interested in learning about different planet system names used in English. What are some typical names or terms used?
Common English Names for Planetary Systems
Planetary systems in English are often named after the central star or object they orbit, such as the 'Solar System' for our own. Others might be referred to by the star's catalog number, like 'Kepler-186 system' or 'Alpha Centauri system.' Additionally, terms like 'exoplanetary system' are used to describe planetary systems beyond our own.
I want to know the naming conventions astronomers use in English when identifying planetary systems. How are these systems typically labeled?
Astronomical Naming Conventions for Planetary Systems
Astronomers usually name planetary systems after their host star, followed by identifiers indicating discovered planets, such as letters (b, c, d) in order of discovery. Popular survey instruments or missions, like Kepler or TESS, often influence these names. The International Astronomical Union standardizes naming conventions to maintain consistency.
Besides the name of the system, what English terminology is used to describe its components, like planets or moons within a star system?
English Terms for Components of Planetary Systems
In English, parts of a planetary system are referred to by terms such as 'planet,' 'moon' (or 'satellite'), 'asteroid belt,' 'comet,' and 'dwarf planet.' The central star is called the 'host star' or 'sun,' and collectively, these elements form the planetary system.
