Mira and Ao try asking different people for information on discovering asteroids, but they aren't able to gather any clues. Though after enjoying a barbeque and some stargazing at the home of Endou-sensei's grandparents, their teacher digs up something...
Oh, that's because light from the sun reflects
off the surface during the full moon,
هذا لأنّ ضوء الشمس ينعكس على سطح
 .القمر عندما يكون بدرًا
Oh, das liegt daran, dass das Sonnenlicht
beim Vollmond frontal einstrahlt,
Eso es porque cuando está llena
la luz del sol le da de frente
Eso es porque cuando está llena
la luz del sol le da de frente
En fait,
Ah, beh... questo è perché durante la luna piena, 
la luce del sole riflessa dalla superficie lunare
É porque a luz do sol reflete
na superfície durante a lua cheia.
Просто свет отражается от поверхности 
полной луны, поэтому становится труднее
