Input interpretation

convert π×(2.77278 au (astronomical units))/(1686.44 days) (1 + sqrt(1 - 0.230835^2)) to kilometers per second

Result

17.65 km/s (kilometers per second)

Additional conversion

17645 m/s (meters per second)

39472 mph (miles per hour)

63523 km/h (kilometers per hour)

Comparison as speed

≈ 0.59 × mean Earth solar orbital velocity ( ≈ 29800 m/s )

≈ 1.1 × Earth-relative launch speed of the New Horizons spacecraft ( 16.26 km/s )

≈ 1.6 × Earth escape velocity ( 11180 m/s )

Comparison as electric charge carrier drift velocity

≈ ( 0.18 ≈ 1/6 ) × electron saturation drift velocity in high-quality silicon at room temperature ( ≈ 1×10^7 cm/s )

Interpretations

speed

electric charge carrier drift velocity
