Jupiter is not seen for about half of the year (Jupiter is in the daytime), and the moon goes around the earth once a month. In theory, Jupiter accompanies the moon about six times a year. If we consider some boundary conditions, such as Jupiter in the early morning or dusk, when the moon is a new moon, it is likely to be invisible, so this scene appears 5-7 times a year, lasting 3-5 days each time. "Jupiter with the Moon" also has a nice name, called the love between the stars and the moon.
