436b

436b is a designation used in astronomy that may refer to a planet in a system labeled by the number 436. In practice, 436b is not a single universally defined object; instead, it can denote the first planet discovered in various different systems, each with its own host star and orbital properties.

In exoplanet catalogs, a planet designated as 436b would be described with the host star’s name, the orbital period, semi-major axis, and estimates of mass and radius, along with the method of discovery. The suffix “b” indicates that it is the first planet identified in that particular system; planets discovered later are labeled with subsequent letters such as “c,” “d,” and so on.

Because the same designation can appear in different databases for different objects, identifying the exact object referred to by 436b requires consulting the specific catalog entry or the discovery paper. Common sources for exoplanet data include the NASA Exoplanet Archive and the Exoplanet.eu database, which provide the host star information, coordinates, and published parameters.

If you have a specific source in mind for 436b, providing the host-star designation or catalog reference will help locate the precise object and its reported characteristics. In the absence of a context, 436b serves as a generic placeholder within exoplanet naming conventions rather than as a uniquely defined object.
