The Lunatik is a military spacecraft on extended patrol in the vicinity of the planet Eqrgp and its moon, with the mission of
repelling Vegan invaders who threaten life on Eqrgp or on its moon. The Vegans' home base is on a planet of the star Vega. As it
happens, Vegans are vegans, but still very vicious toward non-Vegan life forms, especially non-vegan ones. The captain of the
Lunatik endangers his craft's vital mission by running out of fuel, leaving the Lunatik adrift in space, subject to the gravitational
pulls of Eqrgp and its moon. Ignore the gravitational pulls of other bodies.
The Lunatik's navigator notices that for a short while the craft does not change its speed or direction. How far from the center of
Eqrgp is the Lunatik at that time? The distance between the centers of Eqrgp and its moon is 3.91 x 10 m. The mass of Egrqp is
5.03 x 104 kg and the mass of its moon is 1.35 x 10-3 kg.

This time Rick plans to study Pluto's largest moon Charon. Charon has a mass of 1.586 ×1021 kg and a mean radius of 606 km, and might have a nitrogenous atmosphere (N2) just like Pluto. If, for a massive object to have an atmosphere its escape speed must be 12 times greater than the root-mean- square (rms) velocity of the gas (otherwise the gas will slowly leak away over time), what is the maximum temperature that Charon can have and still have a nitrogenous atmosphere?

What would be the orbital period of such a planet? (Such a planet was once postulated, in part to explain the precession of Mercury's orbit. It was even given the name Vulcan, although we now have no evidence that it actually exists. Mercury's precession has been explained by general relativity.)arrow_forwardOne way astrophysicists have identifi ed “extrasolar” planets orbiting distant stars is by observing redshifts or blueshifts in the star’s spectrum due to the fact that he star and planet each revolve around their common center of mass. Consider a star the size of our sun (mass 1.99 x 1030 kg), with a planet the size of Jupiter(1.90 x 1027 kg) in a circular orbit of radius 7.79 x 1011 m and a period of 11.9 years. (a) Find the speed of the star revolving around the system’s center of mass. (b) Assume that Earth is in the planet’s orbital plane, so that at one point in its orbit the star is moving directly toward Earth, and at the opposite point it moves directly away from Earth. How much is 550-nm light redshifted and blueshifted at those two extreme points?arrow_forward
