👉 In the context of astronomy, "sirianian" is a term that describes an object in space with characteristics similar to a star but different from the sun. It can refer to a planet or other celestial body orbiting another star. For example, the Sun and Earth are considered to be "sirian" planets, as they orbit their stars in the same plane, while other planets like Mars, Jupiter, Saturn, Uranus, Neptune, and others orbit their stars at different angles
