Cara Menghitung Roche Limit
learn.whatIsHeading
Roche limit is minimum distance satellite can orbit before tidal forces exceed self-gravity, disrupting it into rings.
Panduan Langkah demi Langkah
- 1Input primary density, satellite density, and mass ratio
- 2Calculate rigid or fluid limit depending on satellite type
- 3Results show minimum stable orbital distance
Contoh Terpecahkan
Masukan
Earth-Moon: Roche limit ~2.46 Earth radii (within Moon orbit)
Hasil
Moon stable but gradually receding
Currently ~384,400 km
Kesalahan Umum yang Harus Dihindari
- ✕Confusing rigid and fluid Roche limits
- ✕Not accounting for density differences
Pertanyaan yang sering diajukan
Are Saturn rings inside Roche limit?
Yes, explaining why rings exist instead of moon.
