traaitan saur mandal ke aathave grah varun (naiptayoon) ka sabse bada upagrah hai aur hamaare saur mandal ke saare chandramaaon mein se saatava sab se bada chandrama hai. agar varun ke saare chandramaaon ka kul dravyamaan dekha jaae to usaka 99.5% is ek upagrah mein nihit hai.[6] traaitan varun ka ikalauta upagrah hai jo apne gurutvaakarshak khichaav se apna akaar gol kar chuka hai. baaki sabhi chandramaaon ke akaar bedhange hain. traaitan ka apna patala vaayumandal bhi hai, jismein naaitrojan ke saath-saath thodi maatra mein methane aur kaarban monooksaaid bhi maujood hain. traaitan ki satah par ausat taapamaan -235.2° seinteegred hai. 1986 mein paas se gujrate hue vauyejar dviteeya yaan ne kuchh aisi tasveerein li jinmein traaitan ke vaataavaran mein baadalon jaisi cheejein nazar I theen. traaitan varun ke ird-gird apni kaksha mein parikrama mein pratigaami chaal rakhata hai[7] aur iski banaavat yam grah (plooto) se milti-julati hai jis se vaigyaanik anumaan lagte hain ke traaitan varun se door kaaipar ghere mein bana tha aur bhatakate hue varun ke paas ja pahuncha jahaaain vah varun ke tagade gurutvaakarshan ki pakad mein aa gaya aur tab se usaki parikrama kar raha hai.[8]

anukram

banaavat

traaitan ki satah par jami hui naaitrojan ki barf ki ek parat hai. uske neeche paani ki barf ki moti parat hai. is parat ke neeche is upagrah ka keindreeya bhaag hai jo patthar aur dhaatuon ka mishran hai. yeh kendreeya bhaag is upagrah ke kul dravyamaan ka do-tihaai hissa hai. vaigyaaniko ka maanana hai ke iski satah par aise jvaalaamukhi aur ushnots (gaayajr) hain jo fatkaar jami hui naaitrojan gas ugalate hain.

  6. traaitan ka dravyamaan: 2.14×a1022 kilo. baaki 12 gyaat upagrahon ka samoocha dravyamaan: 7.53×a1019 kilo, ya 0.35 pratishat. upagrahi chhallon ka dravyamaan inki tulana mein na ke baraabar hai.
  7. pratigaami chaal rakhane ka matlab hai ki jis disha mein varun ghoomta hai, traaitan us se ulati disha mein usaki parikrama karta hai.
