A research paper posted on 14 Oct 2019 further refined the orbit of Epsilon Indi Ab using astrometry, revealing its inclination and thus true mass.
Epsilon Indi Ab
Semi-major axis: 11.55 AU
Orbital period: 45.20 years
Eccentricity: 0.26
Inclination: 64.25 degrees (0 deg = face-on, 90 deg = edge-on)
Mass: 3.25 Jupiters
Confirmed: March 2018
In Orion's Arm, this object corresponds to a planet known as...III. A MesoJovian. I believe we should name these planets soon, hah, and so I've posted my proposal in this thread.
