Apophis sauramandal mean lakhoan aisi chhoti-b di chattane haian, jo soory ki parikrama karate hue kee bar prithvi ke nikat a jati haian. anuman hai ki koee bis lakh kshudr grah prithvi ke nikatavarti aantariksh mean ghoom rahe haian. ausatan har haphte is tarah ka ek kshudr piand prithvi se chandrama tak ki doori doori ke bich se nikal jata hai. ameriki aantariksh adhikaran nasa ke vaijnanik un akashiy pian doan ki bhi hamesha talash mean rahate haian, jo keval kuchh mitar hi b de haian.

aisa hi ek kshudr grah hai 99942 epophis (Apophis). ye lagabhag 275 mitar chau da (1600 phit chau di/adha mil vyas) hai. disanbar 2004 mean vaijnanikoan ne epophis kshudr grah ka pata lagaya tha. ye kshudr grah bhi hamare sauryamandal mean grahoan ke sath soory ke chakkar laga raha hai. vaijnanikoan ke anusar ye grah dhire-dhire dharati ke qarib ata ja raha hai aur shukravar 13 aprail 2029 ko vah pahali bar prithvi ke kafi shaktishali gurutviy keandr ki hol se keval 36 hazar kilomitar (18000 mil) ki doori par se gujarega. yah vahi doori hai, jahaan rediyo aur telivijan karyakram rile karane vale hamare adhikatar sanchar upagrah bhi prithvi ki parikrama kar rahe haian. jahaan tak anuman hai, vah prithvi se takarayega nahian.

yadi us par prithvi ke gurutvakarshan ka asar ho gaya, to kshudr grah sat varsh bad 2036 mean dubara aega aur tab usaka prithvi se takarana lagabhag nishchit lagata hai. vaijnanik ise ‘ki-hol’ asar bata rahe haian. khagolavidoan ke anusar aantariksh mean ghoomane vala kshoodragrah epophis 37014.91 kimi/ prati ghanta ki raphtar se prithvi se takara sakata hai. yadi yah takkar huee, to usaki visphotak shakti hiroshima par girae ge paramanu bam se bhi das lakh guna adhik hogi.

itane b de kshudr grah ke dharati se takarane par yahaan kafi nukasan hoga. usase logoan ki janean jaeangi. isake takarane se vatavaran mean dhool kafi oopar tak jam jaegi. dhool ki vajah se kee saloan tak dharati par poori roshani nahian rahegi. soory ki roshani nahian milane ka asar paudhoan par bhi p dega aur phasalean nahian hoangi. phir bhi ummid hai ki isase poori manav jati khatm nahian hogi. agar ye samudr mean bhi girata hai to bhayanak sunami ka samana karana p dega. isamean bhi karo doan janean jaeangi. 250px|thumb|epophis path
Apophis path vijnan ke anusar prithvi ko atit mean kee bar is tarah ke doosare piandoan ke sath takkar jhelani p di hai. isi ka natija hai jo dharati par kee jagah b de gaddhe haian. is tarah ka sabase pichhala pralayankari piand sadhe chhah karo d sal pahale takaraya tha. usane n jane kitane jiv-jantuoan ki prajatiyoan ka prithvi par se aant kar diya. samajha jata hai ki dayanas aaur is takkar se lupt hone vali sabase prasiddh prajati haian. samasya yah hai ki ham nahian janate ki kab phir aisa hi ho sakata hai. vah laghu grah sanh phraansisko ki kha di jitana b da tha aur aj ke meksiko mean gira tha. is takkar se jo visphot hua, vah das karo d megatan tienati ke barabar tha. prithvi par varshoan tak aandhera chhaya raha. dharati ka vyas 8000 mil ka hai.

is pralay ko talane ke uddeshy se duniyabhar ke vaijnanik isase bachane ke tarike khoj rahe haian. ameriki spes ejeansi nasa ke alava briten aur roos ke aantariksh vaijnanik apane-apane sujhav de chuke haian. roosi vaijnanikoan ne ulka ke takarane ki sthiti se bachane ke lie ek aaupareshan shuroo kiya hai. isamean ulka ko usake raste se bhatakana shamil hai. nasa ne bhi ulka ko raste se hatane ke lie abhiyan shuroo kiya hai. aisa manavarahit aantariksh yan ko ulka se takarakar kiya ja sakata hai. is vikalp par prayog ke lie pichhale saptah nasa ne prashaant mahasagar ke qarib 50 hazar kimi oopar ulka ‘2011sikyoo1’ ko yan se takarakar nasht kiya. ho sakata hai, epophis ke pahale padarpan ke samay hi usaka rasta badalane ya use nasht karane mean aisi saphalata mil jae ki usake dubara lautane ka prashn hi nahian paida ho. philahal dave se kuchh kaha nahian ja sakata. age kya hoga philahal ye ek raj hai.
