description GJ 3293 d Overview
GJ 3293 d is a confirmed exoplanet orbiting the red-dwarf star GJ 3293. It is one of several planets detected in that system through measurements of the star’s radial-velocity variations. The planet is classified as a super-Earth because its minimum mass is several times that of Earth, and its orbit has been discussed in relation to the star’s conservative habitable zone. That designation concerns received stellar energy and does not establish the presence of an atmosphere or life.
help GJ 3293 d FAQ
What kind of star does GJ 3293 d orbit?
GJ 3293 d orbits the red-dwarf star GJ 3293. It is one of several planets detected in that system through changes in the star's radial velocity.
Why is GJ 3293 d called a super-Earth?
It has a minimum mass several times that of Earth, placing it above the terrestrial-planet mass range in common exoplanet classifications. The term does not by itself prove that the planet has an Earth-like surface.
How was GJ 3293 d discovered?
Astronomers measured periodic radial-velocity variations in GJ 3293. The star's motion revealed the gravitational pull of multiple orbiting planets.
Is GJ 3293 d the only planet around its star?
No. It is one of several planets detected in the GJ 3293 system. Its classification as a super-Earth describes its estimated minimum mass, not its position in the system.
