Green star (astronomy) - Wikiwand

In astronomy, a green star is a white or blueish star that appears greenish in some viewing conditions . Under typical viewing conditions, there are no greenish stars, because the color of a star is more or less given by a black-body spectrum. However, a few stars appear greenish to some observers in certain viewing conditions—for example, the optical illusion that a red object can make nearby objects look greenish . Some multiple star systems, such as Antares, have a bright reddish or yellowish star where this contrast makes other stars in the system seem greenish.
