Acomet approaches the sun to within 4.2 au,
and its orbital period is 96 years.
note: au is the abbreviation for astro-
nomical unit, where 1 au = 1.50 x 108 km
is the mean earth-sun distance. thus,
ks1 year/au
a
4.2 au
sun
figure: eliptical orbit of planet.
how far from the sun will the comet travel
before it starts its return journey?
answer in units of au.
