    • Planet (Astron) A celestial body which revolves about the sun in an orbit of a moderate degree of eccentricity. It is distinguished from a comet by the absence of a coma, and by having a less eccentric orbit. See Solar system.
    • Planet A star, as influencing the fate of a men. "There's some ill planet reigns."

    • n planet A star other than a fixed star: a star revolving in an orbit. The sun was formerly considered as a planet, but is now known to be a fixed star. By planet is ordinarily meant a primary planet of the solar system, or body revolving round the sun in a nearly circular orbit. Of these eight are major planets—being, in their order from the sun, Mercury, Venus, the Earth, Mars, Jupiter, Saturn, Uranus, Neptune. There are besides about 300 minor planets known. (See planetoid.) The periodic comets are not regarded as planets. A secondary planet is a satellite, or small body revolving round a primary planet: thus, the moon is a secondary planet. See solar system (under solar), gravitation, Kepler's laws under law), and the names of the major planets.

Unroofed our planet's starlit hall;
Through voids unknown to worlds unseen

At a = 2.35 AU, GJ 849 b is the first Doppler–detected planet discovered around an M dwarf orbiting beyond 0.21 AU, and is only the second Jupiter–mass planet discovered around a star less massive than 0.5 M⊙ .
A Long-Period Jupiter-Mass Planet Orbiting the Nearby M Dwarf GJ849
As the durations of the M dwarf planet surveys increase, it will become evident whether the current observed paucity of gas giants holds for larger orbital separations, or if there exists a separate, larger population of Jupiter–mass planets residing in long–period orbits.
A Long-Period Jupiter-Mass Planet Orbiting the Nearby M Dwarf GJ849
The GJ 849 planetary system is remarkable in two respects: the orbital separation (a = 2.35 AU) of the planet is more than an order of magnitude greater than any other Doppler–detected M dwarf planet, and the system is only the second known to include a Jupiter–mass planet.
A Long-Period Jupiter-Mass Planet Orbiting the Nearby M Dwarf GJ849
The fraction of planets orbiting GK stars within 2.5 AU is also 5.6 ± 1.6%, resulting in a factor of 3 higher likelihood of finding planets orbiting solar–mass stars compared to M dwarfs.

On their way, those planets destroy the disk and any smaller planets that may have been formed there.

This is especially problematic for planet searches since we would like to distinguish between two effects, the well-known planet-metallicity correlation and the in fluence of stellar mass on planet formation.
