The 88 constellations commonly used in the world are all composed of planets, satellites and stars.

Constellation 88 only artificially divides the sky into 88 regions of different sizes and shapes. As long as it is in this area, it is considered as a celestial body in this constellation.

The celestial bodies in the constellation are stars, clusters, nebulae and extragalactic galaxies, excluding planets and satellites.

Because planets are moving, a planet stays in this constellation for a period of time, and after a period of time, it moves to another constellation, so it doesn't count. Not to mention satellites. There is only one natural satellite that we can see with the naked eye, and the position of the moon in the sky is different every day, so it is impossible to count. All the other satellites are beside this planet, which is invisible to the naked eye.
