星际旅行时间计算器 — 公式
## Interstellar Travel Time
At constant velocity, the travel time is simply distance divided by speed.
### Formula
**t = d / v**
- *d* in light-years (1 ly = 9.461 x 10^12 km)
- *v* in km/s
- Result converted to years (1 yr = 3.156 x 10^7 s)
Even at 60 km/s (about the speed of the fastest space probe), Proxima Centauri (4.24 ly) would take over 21 000 years.

计算示例
Proxima Centauri (4.24 ly) at 60 km/s.
- d = 4.24 * 9.461e12 = 4.011e13 km
- v = 60 km/s = 60 * 3.156e7 km/yr = 1.894e9 km/yr
- t = 4.011e13 / 1.894e9
- t = 21 180 years
