Sanigrah

Sanigrah (pratiik: , Saturn) Saur Mandal me Suraj se duur 6th grah hae, Jupiter ke baad duusra sab se barraa hae. Ii ek gas giant hae, jiske average radius dunia ke lagbhag 9 times hae. Iske average density dunia ke makable me one-eighth hae, lekin iske mass 95 dafe jaada hae. Jab Saturn lagbhag Jupiter ke baraabar hae, Sanigrah ke mass khaali one-third hae. Saturn, Suraj ke parikrmaa 9.59 AU (1,434 million km) duur se kare hae, aur iske orbital period 29.45 saal hae.

Sanigrah

Saturn aur iske rings, jiske Cassini orbiter utaris rahaa.

Ii socha jaae hae ki Saturn ke bhittar patthar ke core hae, jiske metallic hydrogen ke ek gahiraa layer surround kare hae, ek biich waala layer jisme liquid hydrogen aur liquid helium hae, aur ek bahaar ke layer jisme gas hae. Sanigrah pale piyar rang hae, jiske kaaran hae iske uppar ke atmosphere me ammonia crystals. Ii socha jaae hae ki ek electrical current metallic hydrogen layer me Saturn ke planetary magnetic field ke kaaran hae, jon dunia ke field se kamjor hae, lekin iske magnetic moment dunia se 580 dafe jaada hae, jiske kaaran hae Saturn ke barraa size. Saturn ke magnetic field, Jupoter ke mukable me one-twentieth hae. Bahaae ke atmosphere bland hae aur isme koi contrast nai hae. Sanigrah ke hawaa ke raftaar 1,800 kilometres per hour (1,100 miles per hour) hae.
