By nauyi na wannan tamkar goma duniya na iya zama wani abu a tsakanin Duniya da kuma Mars. Haka kuma an zaci cewa shi dole ya zama kusa da Sun fiye da tara duniya. Masana kimiyya sun lasafta cewa kewayewa da wani misali ne na goma duniya da aka located game da 60 sau m daga Sun fiye da Earth (ie, a nesa na 60 AU, ko astronomical raka'a). Tara duniya ne ya yi ĩmãni da za a located a nesa daga 500 zuwa 700 AU.

Masana kimiyya sun fara magana game da wanzuwar ta goma duniya bayan karatu 600 Kuiper bel abubuwa. Wasu daga cikin su ze yi "maras kyau" madawwama biyu, wanda aka tilted ta takwas darajõji ga orbital jirgin sama daga cikin manyan taurari a cikin hasken rana tsarin.

Kamar yadda masu bincike, hanya mafi kyau don bayyana wannan nakasawa - to zaton kasancewar wasu unknown duniya. A daidai wannan lokaci, na tara duniya, wanda taro ne da ake zargin 10 sau da taro na Duniya, da cewa shi ne game da rabin da taro na Neptune, ba zai iya bayyana da lura anomaly.
