Fainaghyn Uraanus

Caslys jeianit jeh corys fainaghyn Uraanus (ta ny fainaghyn epsilon/ε, zeta/ζ, mu/μ as nu/ν imraait) myr va jallooit ec y çhamraig NIRCam ec Fodreayrtan Spoar James Webb er 4 Mean Fouyir 2023

Rere castaght, ta fainaghyn Uraanus soit eddyr y phossan lheeadagh ta cruinlaghey Sarn as ny coryssyn ny s'oney ta cruinlaghey Jupiter as Neptioon. Va ny fainaghyn mygeayrt Uraanus feddynit magh er 10 Mayrnt 1977 liorish James L. Elliot, Edward W. Dunham, as Jessica Mink. Chur William Herschel sheese er ny fainaghyn cho foddey sheear as 1789; cha nel rollageyderyn noa-emshiragh shickyr er y feddynys shen er-yn-oyr dy vel ad cho dorraghey as baiht.

Roish 1977 va nuy fainaghyn er lheh enmyssit. Va daa 'ainey elley feddynit magh ayns 1986 ayns jallooyn va jeant ec y taagh spoar Voyager 2, as va daa 'ainey mooie feddynit magh ayns 2003–2005 ayns jallooyn ec Fodreayrtan Spoar Hubble. Rere foddeeaght veih'n phlanaid, ta ny 13 fainaghyn enmyssit 1986U2R/ζ, 6, 5, 4, α, β, η, γ, δ, λ, ε, ν as μ. Rere craue raadeeoil, t'ad anchasley veih mysh 38,000 km da'n fainey 1986U2R/ζ dys 98,000 km da'n fainey μ. Foddee dy vel cryssyn joan baiht as arcyn neuyeant eddyr ny h-ard-ainaghyn. Ta ny fainaghyn feer ghorraghey—cha nel albedo Bond ny fainaghyn ny smoo na 2%. S'liklee dy vel ad jeant ass rio ushtey lesh beggan d'orgaanee fo loaghtey goul-rooragh.

Ta'n chooid smoo jeh ny fainaghyn dullyr as cha nel ad agh reggyryn dy chilomeadaryn er lheead.
