The most stars projected by a planetarium projector is co-held by Chiron 401 installed in the planetarium at Yokkaichi Municipal Museum (Japan) and Chiron II (both manufactured by Goto Inc. in Japan) which can simultaneously project at least 140,000,000 stars as verified in Yokkaichi, Mie, Japan, on 14 - 15 July 2016.
The number of the projected stars by Chiron 401 has been assessed and confirmed by two independent witnesses who are professional astronomers. They used accurate map of NGC 3532 to match the projected stars which traced up to 20th magnitude stars at the planetarium. Both expert witnesses confirmed Chiron401 has projected at least 140,000,000stars by collating the map of NGC3532 and projected stars up to 18th magnitude. They also confirmed the projector projected NGC3532 accurately.
