دومکیت آسمانی جسم ہیں جو زیادہ تر چٹانوں اور دھول سے بنی ہیں جو برف اور گیسوں کے ساتھ مل کر پھنس جاتی ہیں۔ کتنی بار دومکیت ایک نئی دم اگاتا ہے؟
Explanation
A comet grows a tail when it approaches the Sun due to the heat causing the ice to vaporize, releasing gas and dust.
This process forms a glowing coma and tail, which always points away from the Sun due to solar wind.
