Estimate the mass of the Sun from the orbital period of the
Earth (it’s presumed you know what this is !) and the Earth’s
orbital radius of 93 million miles. If the Sun’s radius is 109
times that of the Earth, what is the Sun’s mean density? What is
the acceleration due to gravity on the Sun’s surface? Is it
sensible to go and measure this at night?
A comet orbits the Sun in 4,063 years. What is its average
orbital distance from the Sun? Express your answer in AU (enter
"AU" for units) and round it to the nearest integer.
An asteroid orbits the Sun at an average orbital distance of 1.15
AU. What is its average orbital period? Express your answer in
years (enter "years" for units) and round it to two decimals.

Callisto orbits Jupiter at an average distance of 1.88 106 km
with an orbital period of 0.0457 yr. The Moon, which is one of the
satellites of the Earth orbits its parent at an average distance of
3.84 105 km with an orbital period of 0.07481 yr.(a) Use the above
information to find the orbital speeds of Callisto around Jupiter
and of the Moon around the Earth.

The Venus-Sun distance is 108 million kilometers, and the
Earth-Sun distance is 150 million kilometers. Suppose an imaginary
line from Venus to the Sun forms a right angle with an imaginary
line from Earth to the Sun. How long would it take light to travel
from the Sun to a spaceship halfway along the straight-line path
between Venus and Earth? The time is in minutes.

The closest distance between the sun and Mercury is
dm = 4.6 x 1010m. What is the intensity of
the sun’s light at Mercury?
Mercury has a radius of rmer = 2.4 x
106m. How much power from the sun hits Mercury?
Use the climate model to calculate the average temperature of
Mercury, given a reflectivity of a = 0.07.
At this distance, the temperatures reach 700 K during the day
at the equator. How does this compare to your...
