Calculate the time taken by the Earth to fall from the orbit onto the Sun if its instantaneous radial velocity became zero.
A synchronous satellite, which always remains above the same point on a planet's equator, is put in circular orbit around Neptune so that scientists can study
a surface feature. Neptune rotates once every 16.1 h. Use the data of this table to find the altitude of the satellite.
km
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?
