Cosmic Velocity - Third to Yard per Minute

The third cosmic velocity is approximately 16,700 m/s (16.7 km/s), the minimum speed to escape the Sun's gravity from Earth's orbital position.

v₃ = √(v_sun² - v_Earth²) where v_sun is solar escape velocity from Earth's orbit. Approximately 16.7 km/s relative to Earth.

To km/h: × 3,600. To mph: × 37,282. 16.7 km/s = 60,120 km/h = 37,344 mph.

Voyager missions, future interstellar probes, and calculations for leaving the solar system.

Voyager 1: ~17 km/s relative to Sun (achieved via Jupiter gravity assist). Parker Solar Probe: 163 km/s peak (but toward Sun, not away).

Thinking Voyager was launched at 16.7 km/s — it used gravity assists. Also, confusing with speed needed to escape from Sun's surface (618 km/s).

~17 km/s to leave the solar system from Earth's orbit. Voyagers achieved this with gravity assists from planets.

Yard per minute measures distance in yards traveled in one minute.

1 yd/min = 0.01524 m/s = 0.05486 km/h = 0.9144 m/min.

To yd/s: ÷ 60. To ft/min: × 3. To m/min: × 0.9144.

American football player speeds (50–120 yd/min), slow boat speeds, and some industrial processes.

NFL running back: 100–120 yd/min sprint. Average walking: 50 yd/min.

Confusing with yd/s (60× faster) or mph.

~30 yd/min = 1 mph. Used occasionally in American sports contexts.
