  b ill ion ▁years , ▁the ▁Mil ky ▁Way ▁and ▁And rom eda ▁will ▁complete ▁their ▁mer ger ▁into ▁a ▁giant ▁elli pt ical ▁galax y . ▁During ▁the ▁mer ger , ▁if ▁there ▁is ▁enough ▁gas , ▁the ▁increased ▁gravity ▁will ▁force ▁the ▁gas ▁to ▁the ▁centre ▁of ▁the ▁forming ▁elli pt ical ▁galax y . ▁This ▁may ▁lead ▁to ▁a ▁short ▁period ▁of ▁int ensive ▁star ▁formation ▁called ▁a ▁star bur st . ▁In ▁addition , ▁the ▁inf alling ▁gas ▁will ▁feed ▁the ▁newly ▁formed ▁black ▁hole , ▁transform ing ▁it ▁into ▁an ▁active ▁gal actic ▁nucle us . ▁The ▁force ▁of ▁these ▁interactions ▁will ▁likely ▁push ▁the ▁Sol ar ▁System ▁into ▁the ▁new ▁galax y ' s ▁outer ▁h alo , ▁leaving ▁it ▁relatively ▁un sc athed ▁by ▁the ▁radiation ▁from ▁these ▁coll isions . ▁ ▁It ▁is ▁a ▁common ▁mis con ception ▁that ▁this ▁collision ▁will ▁dis rupt ▁the ▁or bits ▁of ▁the ▁plan ets ▁in ▁the ▁Sol ar ▁System . ▁Although ▁it ▁is ▁true ▁that ▁the ▁gravity ▁of ▁passing ▁stars ▁can ▁det ach ▁plan ets ▁into ▁inter stell ar ▁space , ▁distances ▁between ▁stars ▁are ▁so ▁great ▁that ▁the ▁lik elihood ▁of ▁the ▁Mil ky ▁Way – And rom eda ▁collision ▁causing ▁such ▁dis ruption ▁to ▁any ▁individual ▁star ▁system ▁is ▁neg lig ible . ▁Although ▁the ▁Sol ar ▁System ▁as ▁a ▁whole ▁could ▁be ▁affected ▁by ▁these ▁events , ▁the ▁Sun ▁and ▁plan ets ▁are ▁not ▁expected ▁to ▁be ▁dist urbed . ▁ ▁However , ▁over
