The moon's orbital eccentricity can be calculated using the formula:
e = (ra - rp) / (ra + rp)
Given that rp = 0.27ra, we can substitute the values into the formula:
e = (ra - 0.27ra) / (ra + 0.27ra)
Simplifying the equation:
e = (0.73ra) / (1.27ra)
e = 0.73/1.27
Therefore, the moon's orbital eccentricity is approximately 0.57.
For a moon orbiting its planet, rp
is the shortest distance between the moon and its planet and ra
is the longest distance between the moon and its planet. What is a moon's orbital eccentricity if rp
is equal to 0.27ra
