A planet orbits a Sun-like star at an orbital distance of 40 AU. What is its orbital period?
Solutions
Expert Solution
This problem can be solved by Kepler's law. According to his third law, P^2=a^3 or a^3= p^2
P = period in yrs,
a = the avg distance between the star and the planet in AU.
Since it's given that distance, a = 40 AU,
a^3 = 64000= P^2
or P = square root of 64000= 253 years.

a) At what distance from a 2 solar mass neutron star would a
planet like the Earth be tidally disrupted (that is, literally
pulled apart)? That is, how close would the planet need to be to
the NS for the difference between the NS’s gravity at the center of
the planet and at the surface of the planet to be greater than the
gravity holding the planet together?
b) Would the asteroid Pallas be able to get any closer? (Pallas...

The planet Mars has a diameter of 6772 km, and it orbits the sun
at a distance of 227.9 x 10^6 km. If the sun is assumed to radiate
like a blackbody at 5760 K, and Mars has an albedo of 0.15 (
reflects 15% of incident radiation back to space), estimate the
average temperature of the Martian surface. Ignore the effects of
the thin Martian atmosphere.

Astronomers have discovered a new planet around a nearby
Sun-like star. The following data on the planet is known. It has a
density of 1.4 relative to water along with a mass of 7.8×1027 kg
and a radius of 77,000 km, and its orbital period is 0.52
years.
a) From this information determine the following: the mass and
radius of the planet relative to Earth, semi-major axis of the
planet’s orbit, as well as the mass of the host star....

Is the angular momentum of a planet conserved as it orbits a
star? Explain your answer using torque. Conservation of angular
momentum:
The angular momentum of an object or system is conserved
whenever the total external torque on the object or system is zero.
