In a cosmic revelation that’s turning heads in the astronomical community, the discovery of GJ 3998 d brings an exciting glimpse into the expansive universe surrounding us.
GJ 3998 d, newly identified in 2025, is making waves as a Neptune-like exoplanet that orbits around a modest M-type star. With a mass tipping the scales at 6.07 times that of Earth, it completes a full revolution in just 41.8 days. This swift journey spans a mere 0.189 AU from its star, showcasing an impressive close-knit relationship.
In terms of size, GJ 3998 d is estimated to have a radius 0.209 times that of Jupiter. Its celestial dance around its host star follows a perfectly circular orbit, marking an eccentricity of zero. Much like its discoverers predicted, its stability in orbit is remarkable.
The discovery method via radial velocity adds a fascinating layer to this space story. It underscores the meticulous technology and calculations crucial to unveiling such distant worlds. By tracking the gravitational influence exerted by the planet on its star, astronomers have pieced together this intergalactic puzzle.
