Periode rotasi

Ensiklopedia Pengetahuan Universitas Islam Sultan Agung

Periode rotasi suatu benda astronomis adalah waktu yang dibutuhkan untuk menyelesaikan satu revolusi mengitari sumbu rotasinya relatif terhadap bintang di belakangnya. Periode ini berbeda dengan hari matahari planet, yang mencakup rotasi tambahan untuk memenuhi bagian periode orbit planet selama satu hari.
