The longitude of the ascending node, also known as the right ascension of the ascending node, is one of the orbital elements used to specify the orbit of an object in space. Denoted with the symbol Ω , it is the angle from a specified reference direction, called the origin of longitude , to the direction of the ascending node (☊), as ...
HD 154088 is also being observed under the Keck Eta-Earth radial velocity survey. [8] HD 154088 b is a close match for planet candidate 1 (orbital period = 18.1 days, minimum mass = 6.5 M 🜨), so they may be the same detection.
HD 95086, formally named Aiolos, [7] is a pre-main-sequence star [3] about 282 light-years (86 parsecs) away.Its surface temperature is 7,750 ± 250 K.HD 95086 is somewhat metal-deficient in comparison to the Sun, with a metallicity Fe/H index of −0.25 ± 0.5 (~55%), and is much younger at an age of 13.3 million years.

This star system has a combined apparent magnitude of +2.08 and is located at a distance of about 48.6 light-years (14.9 parsecs) from the Earth. The stellar classification of A5IVnn indicates that the primary is a bluish-white subgiant star that has evolved away from the main sequence after consuming the hydrogen at its core. [ 3 ]
