🚀 Speed & Distance Facts
Human Walking
The average walking speed is 5 km/h. At this pace, it would take about 5 months of non-stop walking to circle the Earth at the equator (40,075 km).
Car Speeds
At 100 km/h, you're traveling about 27.78 meters every second. That's roughly the length of a basketball court in just one second!
Commercial Flight
A Boeing 747 cruising at 900 km/h crosses about 250 meters (length of 2.5 football fields) in a single second.
Light Speed
Light travels at 1,079,252,848.8 km/h. In just one second, light can circle the Earth 7.5 times!
ISS Speed
The International Space Station orbits at about 40,000 km/h, completing a full orbit every 90 minutes - that's 16 sunrises and sunsets per day!
Solar System Travel
At light speed (1.08 billion km/h), it would still take 4.24 years to reach the nearest star system, Alpha Centauri.
Note: This calculator provides theoretical calculations based on constant speed. Actual distances may vary due to acceleration, deceleration, and other real-world factors.
