Practical Example

Let’s calculate parameters for asteroid Juno using typical data:

• Semi-Major Axis: 2.67 AU
• Eccentricity: 0.255
• Inclination: 12.97°
• Mass: 20 × 10¹⁸ kg
• Diameter: 233 km

After entering these values and clicking Calculate, the results are:

• Orbital Period: 4.36 years
• Surface Gravity: 0.244 m/s²
• Escape Velocity: 21.05 m/s

These calculations reveal that while Juno is much smaller than Earth, it still exerts noticeable gravity and requires a modest escape velocity, which can be critical for planning asteroid missions or simulations.
