行星们即将为太阳举办一个生日派对! 水星想感谢太阳，因为他们离得很近（与太阳离得最近的行星是有好处的）。地球享受着太阳的温暖。所有的行星都想赞美太阳的磁性（具有吸引力的）个性。

可是，筹备派对有很多事要做。他们准备了足够的空间容纳木星的所有卫星吗？不要留出间隔。是时候参加这场星光熠熠的活动啦！

这是一本关于太阳系及其所有（星际）居民的图画书，包含许多相关的科普知识。

The planets are throwing Sun a birthday party! Mercury wants to thank Sun for how close they are. (Being the closest planet has its perks.) Earth enjoys Sun's warmth. And all the planets want to celebrate Sun's magnetic personality.

But party planning takes work. Do they even have room for all of Jupiter's moon? Don't space out. It's time for this star-studded event!
