What does Cosmic velocity - first represent?

It is the minimum tangential speed necessary for an object to maintain a stable circular orbit near a celestial body’s surface.

Why convert Cosmic velocity - first to km/s?

Converting to km/s allows expressing orbital speeds in a common unit widely used in aerospace and astronomy for ease of communication and calculation.

Is the conversion factor always 7.9 km/s?

No, 7.9 km/s applies primarily to Earth’s surface orbit and varies for other celestial bodies depending on their mass and radius.

Limitations

The conversion factor of 7.9 km/s specifically applies to Earth’s surface orbital speeds.
Cosmic velocity - first varies with different celestial bodies and must be adjusted accordingly.
Kilometer per second (km/s) measures speed linearly and lacks vector or directional data.
Accuracy depends on precise knowledge of gravitational constants and orbital radius.
