description GJ 3293 b Overview
GJ 3293 b is a giant exoplanet orbiting the nearby M-dwarf star GJ 3293. It was identified through measurements of the host star’s radial-velocity changes, which reveal the gravitational pull of an orbiting planet. The system also contains other detected planetary companions, making GJ 3293 b relevant to studies of planet formation and orbital architecture around low-mass stars. Its mass places it in the Neptune-class range rather than among Earth-sized planets.
help GJ 3293 b FAQ
What type of star does GJ 3293 b orbit?
GJ 3293 b orbits GJ 3293, a nearby M-dwarf star. M dwarfs are cooler and smaller than the Sun, so their planetary systems can have very different irradiation patterns.
How was GJ 3293 b discovered?
It was identified from radial-velocity changes in the host star. The measurements reveal the star's gravitational response to an orbiting planet.
Is GJ 3293 b part of a multi-planet system?
Yes. Other planetary companions have also been detected around GJ 3293. This makes the system useful for comparing planets formed around a low-mass star.
Is GJ 3293 b a gas giant?
It is described as a giant exoplanet, so it is much larger than an Earth-sized rocky planet. Its detailed composition and atmosphere require more than the basic radial-velocity measurement to determine.
