Let’s break down what makes each member special and where they are in their careers right now.
1. MJ
MJ is the mood-maker with a voice that could crack glass in the best way. He signed again with Fantagio in late 2024 and went all in on his solo career. He starred in the musical Winter Wanderer in 2025, and people loved it.
He also shows up on trot singing shows all the time. He finished military service years back, so now he’s free to sing whatever he wants. OSTs, variety shows, those high notes that make you stop breathing. That’s MJ.
2. Jinjin (ASTRO Leader)
Jinjin, as ASTRO’s leader, has navigated the group through its hardest moments with quiet strength. He’s also a credited songwriter and producer on multiple ASTRO tracks, giving the group’s sound a personal touch.
His sub-unit work and behind-the-scenes composing have made him the production anchor. When the group needed someone to hold them together in 2023 and beyond, Jinjin stepped up without hesitation.
3. Cha Eun-woo
Cha Eun-woo is the Best Kpop visual in 2026. Not just of ASTRO, but of the entire generation. His face has launched a thousand brand deals, from skincare to luxury watches.
But he’s not just a pretty face. His acting in dramas like True Beauty and A Good Day to Be a Dog proved he can carry a show.
On June 28, 2025, he enlisted in the Army military band, leaving fans with the hauntingly beautiful solo album ELSE in November 2025. His pre-enlistment fan meeting “THE ROYAL” sold out in seconds.
He’ll be back in January 2027, and the industry is already holding its breath.
4. Yoon San-ha
Sanha went from the baby of the group to a full-blown powerhouse. His vocal evolution over the past few years has been stunning, and his 2024 solo album DUSK showcased a maturity that shocked even longtime fans.
He’s also dipped into acting with roles that highlight his emotional range. As the maknae, he grew up in front of AROHA, and now he’s leading the charge for ASTRO’s next chapter.
ASTRO Legacy – Moonbin And Rocky
Not every member walks the same path, but the bonds formed in ASTRO go deeper than contracts or stage time.
1. Moonbin (Eternal Member)
Role in ASTRO: Main Dancer, Lead Vocalist
Moonbin was the heart of ASTRO’s choreography and one of the most beloved idols of his generation. His passing in April 2023 left a crater in the K-pop world. But his legacy isn’t about loss, it’s about light.
Fantagio and the members honor him through white butterfly symbols and moonlight tributes at every concert. He’s not a former member. He’s eternal.
2. Rocky (Former Member)
Position: Main Dancer, Lead Rapper
Departure Year: 2023
Rocky left ASTRO in early 2023 to pursue his own artistic vision, signing with a new agency to focus on solo music and dance.
But he didn’t leave the family. At the 2025 “The 4th ASTROAD: Stargraphy” concert at Inspire Arena, he came back on stage for old songs. AROHA cried like it was 2016 all over again. He’s still close with the guys. That’s real friendship.
