The least eccentric orbit is the one with the smallest value of eccentricity (e). Among the options given, the orbit with e=0.001 has the least eccentricity, making it the least eccentric orbit.
To find the least eccentric orbit, we need to look for the value of eccentricity (e) that is closest to zero. Eccentricity measures how much an orbit deviates from a perfect circle.
Let's compare the given values of eccentricity:
1. e=0.001: This value is very close to zero and indicates an almost circular orbit.
2. e=0.90: This value is significantly greater than zero and represents a highly elliptical orbit.
3. e=1: An eccentricity of 1 indicates a parabolic orbit, which is more eccentric than a circular orbit.
4. e=0.25: This value is greater than zero but less than 0.90, meaning the orbit is moderately elliptical.
From the given values, e=0.001 has the smallest eccentricity and represents the least eccentric orbit.
