  • Abstract A new Hubble Space Telescope observation of the 7:4 resonant transneptunian binary system (385446) Manwe has shown that, of two previously reported solutions for the orbit of its satellite Thorondor, the prograde one is correct. The orbit has a period of 110.18 ± 0.02 days, semimajor axis of 6670 ± 40 km, and an eccentricity of 0.563 ± 0.007. It will be viewable edge-on from the inner Solar System during 2015–2017, presenting opportunities to observe mutual occultation and eclipse… CONTINUE READING
