There is a possible reasons for it:

1)tamam planets, sapce men musalsal harkat men hen, right from their beginning, aur jis ki waja se un ki berooni satah friction se buri tarha mutassir hoti he yahan tak k kabhi kabhaar friction se itni heat generate hoti he k un planets ki satah par kuch waqfey k lie aag tak lag jati he. aur hamen ye bhi maloom he k jis cheez par friction ka effect ho wo cheez ghhisna(Abrase) shoro ho jati he aur jab koi cheez har taraf se friction se mutassir ho to wo hamesha circular shape men ghhisti (abrasion) he isi lie tamam planets jo k chaaron taraf se musalsal friction se mutassir honey ki waja se ghistey hen yahi waja he k tamam planets hamesha TAQREBAN circular hotey hen.


Evidence: Pakistan men Northern area men river k kinaarey ap ko barey barey irregular boulders (pathar) nazar aen gey wohi boulders jab river k pani ki friction se chaaron taraf se mutassir hotey hen aahista aahitsta ghhis kar apna size b kam krna shoro kar detey hen aur more circular b hotey jatey hen yahan tak k jab aap sea side pe jaen to wahan ki sand ko utha kr ghour se dekhen ye beach sand bohat ziada circular hoti he, ye wohi barey barey boulders hen jinhey hm norhtern areas men friction apply honey se pehley "irregular" dekhtey hen. That's why, friction ki application k baad har cheez size men choti b hojati hen aur circular bhi, bashart ye k friction har taraf se equal amount men apply ho.

umeed he apko mere mushkil andaz k baa wajood samajh agay hogaa. please feel free to ask in case of any objection/misunderstanding. waiting for your reply

Note: sawal english men kia gaya tha to jawab b english men hi hona chahie tha lekin men ne sotcha k ye topic kafi logo k interest ka ho sakta he is lie men ne jawab jahan tak mumkin ho saka urdu men deney ki koshish ki he.

@LEOPARD: see the last line of 1st paragraph of my answer. is men, men ne "TAQREEBAN" ko upper case men isi lie likha he k KOI planet completely rounded nahi hota q k completely rounded honey k lie ye zaroori he k body ko har taraf se equal amount men friction miley tabhi wo complete round ho sakey ga lekin choon k ye 1 ideal case he isi lie hypothetical he in practice it is impossible k koi cheez friction ki abrasion ki waja se 100% rounded ho sakey , ap evidence men mojood example ko b dekh saktey hen beach sand ka koi b particle completely rounded nahi hota it is "nearly rounded" not "rounded"

aap ne zikar kiya k tamam planets musalsil motion me ha jiski waja se un ki upuri setah pe friction hota jiski waja se planets tend acquire approximately rounded shape.. par yahan pe mera question ye ha k wo friction create kese hota he ? uski waja kia he? ku k hme pata he k friction tab create hota he jab do bodies k surfaces apas me ghasetay aur ak dosra air friction hota he jab koi body air k against move kare to create hota he.. yahan pe aasi konsi cheez he jo friction create kar rahi he.. agar air ko le le to wo space me nahi he ..
