The eccentricity of an asteroid's orbit is 0.0380, and the semimajor axis is 3.06 x 1011 m. The Sun's center is at one focus of the asteroid's orbit. (a) How far from this focus is the other focus in meters? (b) What is the ratio of this distance to the solar radius, 6.96 x 108 m?

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. ...

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....

Suppose we decide to send a spacecraft to Saturn, using one
transfer orbit that connects the earth to Saturn. Craft starts in a
circular orbit (centering the Sun) close to Earth (radius 1 AU) and
is to end up in another orbit near Saturn (radius 10 AU). Ignore
the effects of other planets in the solar system.

For the following, quote your numerical answers to two significant figures: a) A binary system consists of two stars orbiting a common center of mass. Star A is a white star of mass MA = 2.02Mo, where Mo = 1.989 x 1030 kg is the mass of the Sun. Its companion, Star B, is a white dwarf with mass Mg = 0.978M. The orbital period of the two objects is observed to be t = 50.09 years. What is the...
