Announced in 2000, the Jovian planet GJ 3021 b ( GJ 3021 being an alternate less-used designation for this star ) orbits about 0.5 astronomical units from HD 1237 A with a minimum mass 3.37 times that of Jupiter, as determined by measuring variations in the radial velocity of the star.

A COUPLE of columns back, I wrote about Jupiter, the planet in our solar system, and the closest of the four gas giants-the so-called Jovian planets which are all composed predominantly of gaseous elements ( primarily hydrogen and helium, but also including a variety of other gases like ammonia and methane ).

In 2000, it was proposed that a Jovian planet is orbiting the system with a period of 750 1050 days . A later analysis of timing variations did not confirm this proposed planet and instead suggested that there was a Jovian planet in an 18.5-year orbit, or a more massive object further out.

"' Gliese 504 b "'( often shortened to "'GJ 504 b "') is a Jovian planet in the system of the young solar analog 59 Virginis ( GJ 504 ), discovered by direct imaging using HiCIAO instrument and AO188 adaptive optics system on the 8.2-meter Subaru Telescope of Mauna Kea Observatory, Hawaii by Kuzuhara et al.
