HOW LONG TO GET THERE…
1. *Moon*: 3 days
– Average distance to Moon ≈ 384,400 km
– Speed = Distance / Time ≈ 384,400 km / 3 days ≈ 128,133 km/day or roughly 1.48 km/s
2. *Mars*: 7 months
– Average distance to Mars ≈ 225 million km (closest approach)
– Time ≈ 7 months ≈ 210 days
– Speed ≈ 225,000,000 km / 210 days ≈ 1,071,429 km/day or roughly 12.4 km/s
3. *Proxima Centauri*: 81,000 years
– Distance ≈ 4.24 light-years ≈ 40.14 trillion km
– Time = 81,000 years ≈ 29,565,000 days
– Speed ≈ 40,140,000,000,000 km / 29,565,000 days ≈ 1,357,000 km/day or roughly 15.7 km/s
4. *Kepler 452b*: 26 million years
– Distance ≈ 1,400 light-years ≈ 13,250 trillion km
– Time = 26,000,000 years ≈ 9,490,000,000 days
– Speed ≈ 13,250,000,000,000 km / 9,490,000,000 days ≈ 1,396 km/day or roughly 0.016 km/s
5. *Center of Milky Way*: 450 million years
– Distance ≈ 27,000 light-years ≈ 255,500 trillion km
– Time = 450,000,000 years ≈ 164,250,000,000 days
– Speed ≈ 255,500,000,000,000 km / 164,250,000,000 days ≈ 1,555 km/day or roughly 0.018 km/s
These speeds are approximations and assume constant velocity, which isn’t realistic for space travel with current tech. The actual speeds of spacecraft vary greatly depending on propulsion methods.
