    Kumbuka: Kitabu hiki kinakwenda kwa vyombo vya habari, karibu miezi mia mbili sasa hujulikana katika mfumo wa jua na zaidi hugunduliwa mara kwa mara. Kati ya sayari kuu, Mercury na Venus tu hawana miezi. Mbali na miezi ya sayari, kuna miezi mingi ya asteroids. Katika kiambatisho hiki, tunaorodhesha tu vitu vikubwa na vya kuvutia ambavyo vinazunguka kila sayari (ikiwa ni pamoja na sayari za kibete). Idadi iliyotolewa kwa kila sayari ni uvumbuzi kupitia mwaka 2015.

    1 R inasimama kwa mzunguko wa retrograde (nyuma kutoka kwa mwelekeo ambao vitu vingi katika mfumo wa jua vinazunguka na kugeuka).

    2 R inasimama kwa mzunguko wa retrograde (nyuma kutoka kwa mwelekeo ambao vitu vingi katika mfumo wa jua vinazunguka na kugeuka).
