Ka'idojin Asali na Ma'aunin Taurari
Babban manufar auna nauyin duniya ta ƙunshi dokar nauyi da Isaac Newton ya gabatar a ƙarni na 17. A bisa ga dokar nauyi, ƙarfin jan hankali tsakanin abubuwa biyu yana daidai gwargwado kai tsaye ga yawansu kuma yana daidai gwargwado da murabba'in nisan da ke tsakaninsu. Za a iya bayyana dabarar lissafi kamar haka:
\[ F = G \frac{m_1 m_2}{r^2} \]
Ina:
– \( F \) shine ƙarfin nauyi,
– \( G \) shine ma'aunin nauyi,
– \( m_1 \) da \( m_2 \) su ne tarin abubuwa biyu,
– da kuma \( r \) shine nisan da ke tsakanin abubuwa biyu.
Ta amfani da wannan ƙa'ida, za mu iya haifar da tarin duniya daga abubuwa daban-daban, kamar motsin wata da ke kewaya duniyar ko wasu abubuwa da ƙarfin nauyi na duniyar ya shafa.

Matakan Aunawa
1. Auna Radius na Zagaye:
Radius na kewayawa shine nisan da ke tsakanin tsakiyar tauraron dan adam zuwa tsakiyar duniyar. Yawanci ana auna shi da kilomita ko mita.
2. Ƙayyade Lokacin Zagayawa:
Lokacin zagaye shine lokacin da tauraron dan adam ke ɗaukarsa don ya zagaya duniya sau ɗaya. Yawanci ana auna shi da daƙiƙa, sa'o'i, ko kwanaki.
3. Amfani da Dokar Kepler ta Uku:
A cewar Dokar Kepler ta Uku, murabba'in lokacin kewayar tauraron dan adam yana daidai da kubiyar radius na kewayar.
\[ T^2 = \frac{4\pi^2 r^3}{G(M + m)} \]
Inda T shine lokacin kewayawa, r shine radius na kewayawa, G shine daidaitaccen nauyi, M shine nauyin duniya, kuma m shine nauyin tauraron dan adam. Ga duniyoyi masu tauraron dan adam waɗanda suka fi ƙanƙanta da nauyinsu (m << M), ana iya sauƙaƙe wannan lissafi zuwa: \[ T^2 \approx \frac{4 \pi^2 r^3}{GM} \] 4. Lissafin Matsakaici na Taurari: Sanin T da r, ana iya ƙididdige nauyin duniyar (M) kamar haka: \[ M \approx \frac{4 \pi^2 r^3}{GT^2} \] Ta amfani da wannan hanyar, an ƙididdige yawan duniyoyi daban-daban a cikin Tsarin Rana tamu da babban daidaito.
