HD 121504 b
Encyclopedia
HD 121504 b is an exoplanet that is likely be slightly less massive than Jupiter
. Although the radial velocity
method that was used to detect the planet can only measure the minimum mass of the planet, it is very unlikely that its true mass
would be much higher.
HD 121504 b orbits the star
at a distance of about one third of Earth's distance from the Sun, and has a slightly eccentric orbit.
Jupiter
Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn,...

Radial velocity
Radial velocity is the velocity of an object in the direction of the line of sight . In astronomy, radial velocity most commonly refers to the spectroscopic radial velocity...

True mass
The term true mass is synonymous with the term mass, but is used in astronomy to differentiate the measured mass of a planet from the lower limit of mass usually obtained from radial velocity techniques...

HD 121504
HD 121504 is an 8th magnitude star in the constellation of Centaurus. It is a yellow dwarf and remarkably similar to our Sun, only slightly brighter like α Centauri A...
