planetal

Planetal is a term used to describe a hypothetical planet-sized object that orbits a star. The term is often used in the context of exoplanets, which are planets that orbit stars outside our solar system. Planets are typically defined as objects that are large enough to be rounded by their own gravity, have cleared their orbits of other debris, and are not massive enough to initiate nuclear fusion in their cores. Planetal objects can range in size from small, rocky planets similar to Earth to massive gas giants like Jupiter. The study of planetals is a key area of research in astronomy, as it helps scientists understand the formation and evolution of planetary systems. Techniques such as the transit method and radial velocity method are commonly used to detect and study exoplanets. The discovery of planetals has expanded our understanding of the universe and the potential for life beyond Earth.
