The distance between the Earth and Mars when the two planets are at oppositionvaries greatly because of the large eccentricity of Mars's orbit. The periheliondistance of a planet is given by rmin = a (1-e) and the aphelion distance by rmax = a (1+ e) where a is the semimajor axis and e the orbital eccentricity. Find the smallestand largest opposition distances assuming that the Earth's orbit is a circle.

In astronomy opposition is defined as a configuration when two astronomicl objects are located at…

A landing craft with mass M is in a circular orbit a distance d above the surface of a planet. The period ofthe orbit is T. The astronauts in the landing craft measure the diameter of the planet to be D. The landing craft sets down at the north pole of the planet. a)What is the weight of a person of mass m as they step out onto the plant’s surface? b)Suppose days on this planet last t seconds (i.e. the planet rotates about its axis once every t seconds).Write an expression for the astronaut’s perceived weight at the equator in terms of their weight at the north pole. (Hint: think about centripetal force)
Consider the Earth's orbit around the Sun to be circular with radius R = 9.30 x 107 mi and it takes 365 days to complete one revolution. What is the distance Earth traveled for one revolution (circumference of a circle is 2??2πR )?
A satellite is in circular polar orbit around Earth at an altitude of 450 km – meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40° latitude? Earth’s radius is 6,370 km.
B) what is the period of the orbit, in hours?

Kepler’s Law relates the period T ( in a sec) of a satellite to the distance from the center of the earth r (in m) to some physical constants as shown: T2 = (2π/ G ME) r3 Where G = Universal Constant of Gravitation and ME is the mass of the earth. A stationary satellite is one that circles the earth in a circular orbit but stays exactly above the same spot on the earth. Calculate the distance above the earth in m for this “geo-synchronous satellite” to orbit, then convert that height to miles.
