The stellar rotation period was found to be close to the proposed period of Pollux b, casting some doubt on the planet's existence. [7] The 2021 study monitored Pollux for 4.25 years and found the rotational period to be 660 ± 15 d , close to Pollux b's orbital period of 590 days.
A planet in the Solar System beyond the asteroid belt, and hence refers to the gas giants. Jupiter, Saturn, Uranus and Neptune Pulsar planet: A planet that orbits a pulsar or a rapidly rotating neutron star. PSR B1257+12 A, B and C: Rogue planet: Also known as an interstellar planet. A planet that is not bound to any star, stellar remnant or ...
These are lists of planets.A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk.
Before 2006, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto were considered as planets. Below is a partial list of these mnemonics: "Men Very Easily Make Jugs Serve Useful Needs, Perhaps" – The structure of this sentence, which is current in the 1950s, suggests that it may have originated before Pluto's discovery.
Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten; The days of the week; e.g., TH for Thursday; Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and ...
This is a list of named minor planets in an alphabetical, case-insensitive order grouped by the first letter of their name. [a] [b] New namings, typically proposed by the discoverer and approved by the Working Group for Small Bodies Nomenclature (WGSBN) of the International Astronomical Union, are published nowadays in their WGSBN Bulletin and summarized in a dedicated list several times a year.

Planet V is a hypothetical fifth terrestrial planet posited by NASA scientists John Chambers and Jack J. Lissauer to have once existed between Mars and the asteroid belt.In their hypothesis the Late Heavy Bombardment of the Hadean era began after perturbations from the other terrestrial planets caused Planet V's orbit to cross into the asteroid belt.
