Trivia / Astro

• Approval of God: Moon Bin's cover of "24 Hours" was acknowledged by Lia Kim (the choreographer behind the original dance) on 'Differential Class' and received a lot of praise from her. She talked about how he developed and made his own interpretation to the dance, saying that it made her proud.
• Blooper: The behind the scenes of an MV-filming are usually full of these. In the making of "Knock" in particular, the members just kept on laughing while shooting for the more serious scenes of the music video.
• Creator's Favorite: Out of all the songs he has composed, Rocky seems to favour "When the Wind Blows" a lot, especially due to the fact that it was his first self-composed track.
  • In Jinjin's case, "My Zone" seems to fit the bill quite accurately.
• DVD Commentary: For "Switch On", they released an almost 30-minute commentary on their Youtube channel, talking about the production and behind the scenes of each of the tracks.
• Dye Hard: Eunwoo's hair during the promotions for "All Yours" went through multiple color changes- from silvery blue, to silver, to blonde, to pink and then finally back to his usual black hair.
• Dyeing for Your Art: Most often seen with Jinjin, though the other members have also had to dye their hair numerous times, depending on the concepts.

• Fan Community Nicknames: The fandom was officially named Aroha on 23rd February, the same day as the group's debut anniversary. The members announced the fandom name during their debut showcase.
• Fountain of Memes: The whole group. Special mention goes to Moon Bin, whom the fandom has affectionately nicknamed "Meme-bin" for this.
• No-Hit Wonder: While "Crazy Sexy Cool" and "After Midnight" did get some popularity and praise outside of the fandom, they are yet to have a typical 'hit single', the lack of which can often cause dissonance among people who are unaware of Astro as a group. Despite this, they have quite a sizeable fandom, especially in South Korea, because of their rich and varied discography, with Eunwoo's dramas playing a significant role in familiarising the group's name outside of the fandom.
• Non-Singing Voice: Jinjin's singing voice is very different from his usual deep voice and the voice he uses for rapping.
• Referenced by...: The lyics of "Footprint", written by Moon Bin, contains references to all their previous title tracks, in chronological order.
• What Could Have Been:
  • Sanha was initially meant to debut as a solo artist. This is said to be one of the reasons why he doesn't have a stage name, and just goes by his original name, unlike most of the other members.
  • Jinjin had originally planned to audition for YG before he received a call from Fantagio.
  • One of the main reasons Rocky is an idol today... is a Nintendo Wii of all things. He was initially part of the four-member cast for "Billy Elliot the Music" (at 11 years old), but gave up the opportunity in order to join Fantagio and train as an idol after a long discussion with his parents which basically ended with his father telling him that he would buy him the Nintendo Wii if he agreed to join Fantagio.
