1. Planetary system

   A planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with the planetary system revolving around it, including Earth, forms the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems. As of 1 February 2023, there are 5,307 confirmed exoplanets in 3,910 planetary systems, with 853 systems having more than one planet. Debris disks are also known to be common, though other objects are more difficult to observe. Of particular interest to astrobiology is the habitable zone of planetary systems where planets could have surface liquid water, and thus the capacity to support Earth-like life.

1. Planetary system

   A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system. Generally speaking, planetary systems describe systems with one or more planets, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets and planetesimals as well as discernable features including circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System. The interchangeable terms extrasolar system and exoplanetary system are sometimes used in reference to other planetary systems. Individually they may be referred to as system prefixed by the name of the star or star system that it orbits or sometimes simply the name of the star system. Before the 16th century and Copernican heliocentrism, human knowledge of planetary systems was limited to heliocentrism and our own planetary system. Despite the discovery and exploration of the Solar System and centuries of conjecture, it remained this way until the groundbreaking discovery of the unusual PSR B1257+12 system and its extrasolar planets, confirmed in 1992, which holds a number of significant records, including the first discovered, as well as the first pulsar, multi-star planetary system.

Examples of planetary system in a Sentence

1. Robert De Rosa:

   There are still a lot of open questions about this system, for example, we do not conclusively know where or how the planet formed. It is likely that both observers and theorists alike will be studying HD 106906 for years to come, unraveling the many mysteries of this remarkable planetary system.

2. Amir Siraj:

   Presumably, it was produced by another star, got kicked out of that star's planetary system and just so happened to make its way to our solar system and collide with Earth.

3. Paul Kalas:

   Stars need to pass very close to a planetary system to have significant effect.

4. Ellen Stofan:

   I think there has to be in the universe -- how easy it's going to be to find, is another question, statistically every time you're looking at a star you're likely to be looking at a planetary system. Play the math game, there's billions of stars, so eventually you'll come out saying there has to be another body where life could have evolved to a fairly sophisticated level.
