如何计算Satellite Period
learn.whatIsHeading
Satellite orbital period (Kepler third law) depends on orbital radius and central body mass: T² ∝ a³.
公式
Apply T = 2π√(a³/GM)
- T
- 2π√(a³/GM) — 2π√(a³/GM)
- GM
- GM value — Variable used in the calculation
分步指南
- 1Input orbital radius or planet name with altitude
- 2Apply T = 2π√(a³/GM)
- 3Results show period in hours/days
例题解析
输入
ISS at 400 km altitude around Earth
结果
T ≈ 90 minutes
16 orbits per day
常见错误注意事项
- ✕Confusing orbital radius with altitude
- ✕Forgetting Earth radius in altitude conversion
常见问题
Does satellite speed change with altitude?
Yes, inverse √r relationship; lower orbits faster.
