Question
In recent years, scientists have discovered hundreds
of planets orbiting other stars. Some of these planets
are in orbits that are similar to that of earth, which
orbits the sun (Msun 1.99 x 1030 kg) at a distance
of 1.50 x 1011 m, called 1 astronomical unit (1 au).
Others have extreme orbits that are much different
from anything in our solar system. The following
problem relates to one of these planets that follows
circular orbit around its star.
Part A
Kepler-42c orbits at a very close 0.0058 au from a small star with a mass that is 0.13 that of the sun. How long is a "year" on this
world? Assume the orbital period of earth is 365 days.
Express your answer in hours.
