Mercury Planet Ki Maloomat: Sooraj Ka Sab Se Qareebi Hamsaya

Mercury solar system ka sab se ajeeb planet hai, aur ye baat aksar nazar andaz ho jati hai kyunke Mars ki tarah is par zindagi ki baat nahi hoti aur Saturn ki tarah iske paas khoobsurat chalay nahi.

Lekin zara ye socheiye. Ek aisa planet jahan din mein chaar sau tees degree garmi ho aur raat mein manfi ek sau assi degree sardi. Ek aisa planet jo sooraj ke sab se qareeb hai lekin uske qutbain par arbon saal se baraf jami hui hai. Aur ek aisa planet jahan ek din uske apne saal se lamba hota hai.

Ye tamam baatein sach hain aur is guide mein hum in sab ki wajah samjhenge.

Mercury Ki Bunyadi Maloomat

Mercury sooraj ke sab se qareeb wala planet hai aur hamare solar system ka sab se chota planet bhi. Pluto ke planet ka darja khatam hone ke baad ye khitab Mercury ko mila.

Iska qatr lagbhag chaar hazar aath sau tehattar kilometer hai. Ye itna chota hai ke Jupiter ka chand Ganymede aur Saturn ka chand Titan dono is se bare hain. Lekin ek farq hai. Mercury un chandon se kaheen zyada bhaari hai, aur is ki wajah aage samjhenge.

Sooraj se iska aausat faasla lagbhag paanch karor aithasath lakh kilometer hai, yani Earth ke faasle ka lagbhag ek tihai. Sooraj ke gird ek chakkar lagane mein isay sirf athasi din lagte hain, jo solar system mein sab se kam hai. Isi tez raftari ki wajah se Romi tehzeeb mein iska naam apne devta ke paighambar ke naam par rakha gaya jo bohot tez chalta tha.

Iske koi chand nahi hain aur na hi koi chalay. Iski wajah ye hai ke ye sooraj ke itne qareeb hai ke sooraj ki kashish kisi bhi chand ko Mercury se cheen legi.

Sab Se Ajeeb Baat: Yahan Din Saal Se Lamba Hai

Ye Mercury ki sab se hairan kun khoobi hai aur ise samajhne ke liye thora dhyan darkar hai.

Mercury apne mehwar par bohot ahista ghoomta hai. Ek chakkar mukammal karne mein isay unsath din lagte hain, jabke Earth ye kaam chobees ghante mein kar leti hai.

Ab yahan ek dilchasp riyazi tanasub hai. Mercury sooraj ke gird do chakkar lagata hai to isi arse mein woh apne mehwar par theek teen chakkar lagata hai. Isay teen ba do resonance kehte hain aur ye sooraj ki kashish ke asar se paida hua hai.

Is tanasub ka ajeeb nateeja ye nikalta hai ke agar aap Mercury ki satah par khare ho kar ye ginein ke ek sooraj ke nikalne se agle sooraj ke nikalne tak kitna waqt lagta hai, to jawab aata hai ek sau chhattar Earth din. Jabke Mercury ka poora saal sirf athasi din ka hai.

Yani Mercury par ek din uske do saal ke barabar hai.

Aur is se bhi ajeeb baat ye hai ke Mercury ke kuch ilaqon mein aap sooraj ko aasman mein chalte huye, rukte huye, thora peeche jate huye aur phir aage barhte huye dekh sakte hain. Iski wajah ye hai ke Mercury ka madaar bilkul gol nahi balke kaafi bezawi hai, aur jab woh sooraj ke sab se qareeb hota hai to uski madaari raftar itni barh jati hai ke woh apni ghoomne ki raftar se aage nikal jati hai.

Garmi Aur Sardi Ki Intiha

Mercury sooraj ke qareeb hai, is liye qudrati tor par wahan garmi zyada honi chahiye. Aur waqai hai. Din ke waqt satah ka darjah hararat chaar sau tees degree Celsius tak pohanch jata hai. Ye itni garmi hai ke seesa, tin aur zinc sab pighal jayein.

Lekin ab raat ki baat karein. Raat ko wahan darjah hararat manfi ek sau assi degree Celsius tak gir jata hai. Ye chhe sau degree se zyada ka farq hai, jo solar system ke kisi bhi planet mein sab se zyada hai.

Aisa kyun hota hai? Iski wajah ye hai ke Mercury ke paas koi qabil e zikr fiza nahi. Earth par fiza ek kambal ka kaam karti hai jo din mein garmi ko rok deti hai aur raat mein use bahar nikalne se rokti hai. Mercury ke paas ye kambal hai hi nahi. Sooraj ki roshni seedha satah par parti hai aur jaise hi woh hissa andhere mein jata hai, saari garmi foran space mein nikal jati hai.

Waise Mercury sab se garam planet nahi hai. Ye khitab Venus ke paas hai jo Mercury se door hone ke bawajood zyada garam hai kyunke uski motti fiza garmi ko qaid kar leti hai. Ye tafseel se Venus Kaise Bana mein samjhaya gaya hai.

Hairan Kun Darayaft: Mercury Par Baraf Hai

Ye baat pehli nazar mein namumkin lagti hai. Sooraj ke sab se qareeb planet par baraf kaise ho sakti hai?

Jawab Mercury ke mehwar mein hai. Earth ka mehwar lagbhag saarhe teetees degree jhuka hua hai, isi liye hamare yahan mausam badalte hain. Lekin Mercury ka mehwar lagbhag bilkul seedha hai, sirf do degree se bhi kam jhukav ke sath.

Iska nateeja ye hai ke Mercury ke qutbain par sooraj kabhi seedha nahi parta. Aur wahan kuch aise gehre crater hain jinke andar sooraj ki roshni kabhi pohanchi hi nahi. Un craters ki tehon mein arbon saal se hamesha andhera aur sardi hai, jahan darjah hararat manfi do sau degree se bhi neeche rehta hai.

Aur wahin baraf jami hui hai. Radar aur MESSENGER mission ke data ne is baat ki tasdeeq ki hai ke un andhere craters mein paani ki baraf mojood hai. Ye baraf shayad comets ke takrane se wahan pohanchi.

Mercury Ka Bara Loha Core

Mercury ki ek aur ajeeb khoobi uska andaroni sakht hai. Aam tor par planets ka core unke size ka ek chota hissa hota hai. Earth ka core uske qatr ka lagbhag aadha hai.

Lekin Mercury ka core uske qatr ka lagbhag pachasi feesad hai. Ye lohe ka bana ek zabardast bara gola hai aur uske upar chatanon ki sirf ek patli si tehh hai.

Ye tanasub itna ghair mamooli hai ke iski wajah scientists ko pareshan karti rahi hai. Sab se maqbool nazariya giant impact ka hai. Nazariye ke mutabiq Mercury shuru mein kaafi bara tha aur uski chatanon ki tehh bhi motti thi. Phir solar system ke ibtidai afra tafri ke daur mein koi bara jism us se takra gaya aur us takrao ne uski bahri chatanon ki bari miqdar noch kar space mein phaink di. Jo bacha woh zyada tar core hi tha.

Ek doosra nazariya ye hai ke sooraj ki intihai garmi ne Mercury ki bahri tehon ko waqt ke sath waporize kar diya.

Is bare lohe ke core ki wajah se Mercury ka apna magnetic field bhi hai, jo hairan kun hai kyunke itne chote planet mein ye tawaqqo nahi ki jati thi.

Mercury Sikur Raha Hai

Ye ek aur dilchasp haqeeqat hai. Mercury ki satah par lambi lambi cheelein aur uthi hui daraarein nazar aati hain jinhein lobate scarps kehte hain. In mein se kuch sainkron kilometer lambi aur ek kilometer se zyada oonchi hain.

Ye kaise bani? Jab Mercury bana to woh bohot garam tha. Waqt ke sath uska bara lohe wala core thanda hone laga aur thanda hote huye sikurne laga. Jab core sikra to upar wali chatanon ki tehh ko bhi sikurna para, aur woh sikurte huye jagah jagah se toot kar upar uth gayi.

Andaza hai ke Mercury apni tareekh mein lagbhag saat kilometer qatr mein sikur chuka hai. Aur MESSENGER ke data se pata chala ke ye amal shayad aaj bhi jari hai, yani Mercury par bhoochaal aane ka imkaan mojood hai. Zameen par ye amal kaise chalta hai, ye Earthquake Kyun Aata Hai mein tafseel se hai.

Caloris Basin: Ek Zabardast Nishan

Mercury ki satah par sab se namayan cheez Caloris Basin hai. Ye ek bohot bara crater hai jo lagbhag pandra sau kilometer chaura hai. Ye kisi bohot bare asteroid ke takrane se bana.

Us takrao ki shiddat itni zyada thi ke uski laherein poore planet mein safar kar ke theek doosri taraf ja kar milin, aur wahan ki zameen ubhar kar ajeeb sakal ikhtiyar kar gayi. Us ilaqe ko weird terrain kaha jata hai.

Aise takrao ka Earth ke liye kya matlab ho sakta hai, ye Asteroid Earth Se Takra Sakta Hai mein bayan kiya gaya hai.

Kaun Kaun Mercury Tak Pohancha?

Mercury tak pohanchna hairan kun tor par mushkil hai. Wajah ye hai ke jaise jaise koi space craft sooraj ki taraf jata hai, sooraj ki kashish usay tez karti jati hai. Mercury ke gird madaar mein aane ke liye usay is raftar ko kam karna parta hai, jis ke liye bohot zyada eendhan chahiye.

Sirf teen missions ab tak wahan gaye hain. Mariner Ten unees sau chauhattar mein teen baar qareeb se guzra aur planet ka lagbhag aadha hissa mapa. MESSENGER do hazar gyara mein madaar mein daakhil hua aur chaar saal tak poore planet ka naqsha banaya. Aaj BepiColombo naam ka mission jo Yourop aur Japan ka mushtarka hai, Mercury ki taraf ja raha hai aur woh kai baar planets ke gird chakkar kaat kar apni raftar kam kar raha hai.

Mercury Ko Kaise Dekhein?

Mercury ko dekhna asaan nahi. Chunke ye sooraj ke qareeb hai, ye hamesha sooraj ke aas paas nazar aata hai aur is liye ya to sooraj tuloo hone se thori der pehle ufaq par nazar aata hai ya ghuroob ke thori der baad.

Ek mashhoor riwayat hai ke Copernicus ne apni saari zindagi mein kabhi Mercury nahi dekh saka, halanke ye baat tareekhi tor par mukammal tasdeek shuda nahi.

Agar aap dekhna chahein to us waqt ka intezar karein jab ye sooraj se apne sab se zyada zaawiyai faasle par ho, jise greatest elongation kehte hain. Aisa saal mein kai baar hota hai. Us waqt ufaq ke bilkul saaf hone ki zaroorat hoti hai aur koi imarat ya pahar raste mein nahi hona chahiye.

Ek intibah: Kabhi bhi doorbeen ya binocular se us waqt aasman mein Mercury talash na karein jab sooraj upar mojood ho. Ghalti se sooraj aa jaye to aankh ki roshni hamesha ke liye ja sakti hai.

Aakhri Baat

Mercury sirf ek jhulsa hua chota pathar nahi. Ye ek aisa planet hai jo apne andar solar system ke ibtidai daur ki afra tafri ki gawahi liye hue hai. Uska bara lohe ka core kisi zabardast takrao ki kahani sunata hai, uski daraarein uske thande hone ki, aur uske andhere craters mein jami baraf is baat ki ke qudrat mein ghair mumkin lagne wali cheezein bhi mumkin ho jati hain.
