Astro

Astro (; stylized in all caps) is a South Korean boy band formed by Fantagio. The group is composed of four members: MJ, Jinjin, Cha Eun-woo, and Yoon San-ha. Originally a six-piece group, Rocky departed from the group on February 28, 2023, and Moonbin died on April 19, 2023. They debuted on February 23, 2016, with the extended play Spring Up and were subsequently named as one of the best new K-pop acts of 2016 by Billboard. Career Pre-debut Astro was formed through the rookie talent development program "iTeen Boys", which was created by their agency Fantagio. In August 2015, the final member line-up and group name were announced. The same month, the group starred in a web drama titled To Be Continued, which aimed to introduce them to the public. The drama featured the members as themselves, as well as Kim Sae-ron, Seo Kang-joon, and the girl group Hello Venus. After their web drama finished airing, the group started the "Meet U" project. As part of the project, Astro traveled through South Korea, covering songs in front of crowds and holding fan meetings. Along with the performances, a KakaoTalk Plus Friends account was set up. Fantagio stated that once the group had gathered 10,000 friends on the app, they would announce their official debut date. The goal was met by December 2015. Their debut showcase, held on January 28, 2016, was sold out in under a minute and far exceeded the original limit of 1,000 attendants. There, they also announced their official fan club name, Aroha.
