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?
Which of these is an example of an energy source that could exist on Europa (or beneath its surface) and help enable life in a Europan ocean?
a Volcanoes and/or hydrothermal vents on the seafloor
b Solar flares from the Sun that penetrate Europa's ice and send radiation into the liquid-water ocean
c Europa's rapid motion as it orbits Jupiter
d The combustion of fossils fuels beneath the surface, similar to burning coal in the Earth's crust
Why is Neptune a deep blue color?
