Compute the orbital period from the orbital radius.
输入引力参数 μ 与轨道半径 r,求轨道周期。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Circular orbital period | T = 2π√(r³/GM) | Kepler's 3rd law (1619), derived by Newton |
| Earth GM | GM⊕ = 3.986004418×10¹⁴ m³/s² | IERS 2010 / WGS 84 |
| Geosynchronous orbit | r≈42,164 km gives T≈23h56m | Classical result |
