An asteroid is in an orbit around the sun whose closest point to the sun has a radius R and whose most distant point has a radius 9R, where R is equal to the radius of the earth's orbit = 1 AU = 1.5 x 10^11 m. 1. What is the asteroid's speed when it is closest to the sun? 2. How does this compare with the earth's orbital speed? 3. What is the period of this orbit, in years?
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, th
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...

The orbit of a 1.5 ✕ 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.850 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 ✕ 1011 m.) (a)What is its orbital eccentricity? (b)What is its period? (Enter your answer in yr.) (c)At aphelion what is the potential energy (in J) of the comet—Sun system?

A. The Sun travels in a circular orbit at a velocity of 220 km/second at a distance of 8.0 kiloparsecs from the center of the Galaxy (note that these numbers are slightly different from those in your book). Calculate the number of years it takes the Sun to complete an orbit (i.e., the circumference of a circle with an 8.0 kiloparsec radius) around the center of the Galaxy. (There are 3.1 x 1013 kilometers/parsec and 3.2 x 107 seconds/year.) B....

2. (10 points) The Hohmann transfer orbit, proposed by Walter Hohmann in 1925, is the most energy- efficient means of traveling from a circular orbit of radius r, to another circular orbit of radius r. The maneuver consists of two engine burns. The first burm places the spacecraft into an elliptical orbit with ri and r2 as the distances of closest and farthest approach (not necessarily respectively). Once the distance rz is reached, a second burn takes the spacecraft into...
