Watched episode 12:
it's too bad they did not discover anything new. But the lessons learned are important. One day Mira and Ao could discover a new asteroid if they try hard enough. They met plenty of nice people along the way as well.
a little sad this is the final episode. Going to miss this relaxing anime. Going to continue following the story of Mira and Ao on the manga.
ok.... now I have to put a koisuru asteroid cd, along with magia and nekopara on my cdjapan shopping cart. To be ordered once covid calms down. ><
