Xiddigga Gliese 876 wuxuu ku yaalaa meel aad ugu dhow nidaamka qoraxda. Sida laga soo xigtay cabbirrada astrometric ee ay samaysay dayax gacmeedka Hipparcos, xiddiggu wuxuu muujinayaa parallax ah 213.28 milliarcseconds, taas oo u dhiganta masaafo ah 4.69 parsecs (15.3 ly), oo hadda ka dhigeysa xiddigga saddexaad ee ugu dhow ee la yaqaan oo leh meerayaal ku wareegsan, ka dib Epsilon Eridani iyo Gliese 674. In kasta oo ay aad ugu dhow yihiin dhulka, xiddiggu wuu madoobaaday oo indhaha ayaa ka maqan oo waxaa lagu arki karaa oo keliya iyadoo la adeegsanayo telescope. Su'aal: Qalab noocee ah ayaa loo baahan yahay si loo daawado xiddigga?
