The answer will be revealed next week.
Question from the week before:
What is the orbital eccentricity of the just-named and discovered interstellar asteroid 1I/'Oumuamua? (Wikipedia: The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, values between 0 and 1 form an elliptical orbit, 1 is a parabolic escape orbit, and greater than 1 is a hyperbola.)
The orbital eccentricity of the just-named and discovered interstellar asteroid 1I/'Oumuamua is approximately 1.2, the greatest ever determined.
