HD 98649 is a G-class yellow dwarf star.
From 1998 to 2012, the star was under observance from "the CORALIE echelle spectrograph at La Silla Observatory".
The discoverers noted, "HD 98649b is in the top five of the most eccentric planetary orbit and the most eccentric planet known with a period larger than 600 days." The reason for this eccentricity is unknown. They also submit it as a "candidate for direct imaging", once it gets out to "10.4 AU at apoastron" and 250 milliarcseconds of separation relative to Earth.
