==Periode rotasi==
{{utama|Periode rotasi}}
Periode rotasi suatu [[benda astronomi|benda]] [[astronomi]]s adalah waktu yang dibutuhkan untuk menyelesaikan satu revolusi mengitari [[sumbu rotasi]]nya relatif terhadap bintang di belakangnya. Periode ini berbeda dengan [[hari sinodis|hari matahari]] planet, yang mencakup rotasi tambahan untuk memenuhi bagian [[periode orbit]] planet selama satu hari.
