There are at least 5 artists named Astro:

1. Astro is a chilean indie-eclectric-electronic band, first formed in 2008. The group consisted of members: Andrés Nusser, Octavio Caviares, Nicolás Arancibia and Daniel Varas. The band cites Peter Gabriel, David Bowie, Genesis, and MGMT as early influences on their music. Astro released its first EP Le Disc de Astrou in 2009, the quartet released its first full-length album, Astro in 2011. Despite being entirely in Spanish, the album received attention from American music critics. NPR Music featured the album as part of its First Listen series in 2012. Jasmine Garsd called Astro one of her favorite albums, referring to it as "infectiously cheery, lighthearted and danceable." She described them as musical cognates with American bands such as MGMT, Animal Collective, and Passion Pit. In 2015, they released their third album, Chicos de la Luz.

2. ASTRO (아스트로) is a South Korean boy group formed by Fantagio in 2015. The group currently consists of 4 members: MJ (엠제이), Jinjin (진진), Eunwoo (은우), and Sanha (산하). They debuted as a six-member piece, on February 23, 2016 with the mini-album Spring Up along with its title track 숨바꼭질 (Hide & Seek).

The group's former members include Rocky (라키), who made his departure from both the group and Fantagio on February 28, 2023, following the decision not to renew his contract and Moonbin (문빈), who passed away on April 19th, 2023.

The group had two sub-units, known as JINJIN&ROCKY and MOONBIN&SANHA, however they were both disbanded due to the subsequent departure of Rocky and the passing of Moon Bin.

3. ASTRO is Hiroshi Hasegawa's solo 'space-noise' project. Hasegawa is best known as a founding member of Japanese noise legends C.C.C.C. (also Astromero, Astral Travelling Unity, Senssurround Orchestra, YBO²). He has begun his solo unit ASTRO with analog synthesizers in 1993 as well as playing in C.C.C.C. Though his solo focuses on music that stems from a similarly analogue mindset, conjuring feverish dreamscapes from primitive oscillators, ring modulators and field recordings. In this instance, Hasegawa's endeavours seem to marry Japanese harsh noise convention with more psychedelically charged sounds, throwing together a blistering arsenal of noise signals with Acid Mothers Temple-style far-out-ness.
