Students have asked these similar questions
What is the observed angular speed of
Neptune, along the ecliptic of Earth, when it is
at opposition, in units of arc minutes / day?
Presume the orbits are circular. Earth has
orbital speeds of 30km/s and Neptune has
5.43km/s, Neptune here has orbital radius
30.1 AU. Now looking at Uranus for the same
condition, in what direction along the ecliptic
will it be traveling?
Uranus and neptune have almost similar masses. Which of them will exert the greater gravity towards the earth? Why? Explain
Given the masses and radil of Uranus and Neptune, calculate the gravity at the "surface" of each of
the planets.
