Last week's question:

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.)

Answer:

The answer will be revealed next week.

Question from the week before:

What are Bok Globules?

Answer:

Bok Globules are small, cold, dense and isolated clouds or nebulae of gas and dust where young stars are believed to be born. They are named after the Dutch American astronomer Bart J. Bok.
