Question
A comet on an unbound orbit around the Sun might have which of the following properties?
a) An elliptical orbit
b) An eccentricity greater than 1
c) An orbital period of less than 1 million years.
d) Positive total energy measured against the Sun
e) It is possible for a comet on a bound orbit to have all of these properties
f) (a) and (b)
g) (a) and (c)
h) (a) and (d)
i) (b) and (c)
j) (b) and (d)
k) (c) and (d)
l) (a), (b), and (c)
m) (a), (b), and (d)
n) (a), (c), and (d)
o) (b), (c), and (d)
Explanation / Answer
The usual term for those types of comets, "non-periodic". Which means a one time only appearance around the Sun. The orbit would be hyperbolic (unbounded), not elliptical (bounded). so choice (e ) is correct
