About the Planets

About the Planets The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris. The first four planets from

Glossary term: Planetary System

Planetary systems can also be found around components of multiple star systems, such as the planet orbiting Proxima Centauri, the nearest star to the Sun and a member of a triple star system. There are also a handful of circumbinary planets, which orbit both stars of a binary star system.

Four classes of planetary systems

Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers from the Universities of Bern and Geneva, as well as from the National Centre of Competence in Research PlanetS, have now shown for the first time that there are in fact four types of planetary systems.

Researchers classify four architecture types of planetary systems

Therefore, the team set out to solve this problem by developing a model-independent framework to organise systems depending on the distribution of their planetary masses using two parameters. The first is the coefficient of similarity, C S, which assesses the change in mass between neighbouring planets, and the second is the coefficient of variation, C V, which is the
