In a distant star system there are many inhabitable planets. One of these planets is named Qomar. Qomar is 3.2 AU's from its star and takes 6.5 Earth years to go around its star once. There is another planet in the same star system called Ferenginar. Ferenginar is 0.9 AUs from the star. What is the length of a Ferengi year (on Ferenginar) in terms of Earth years?
In the year 8000 (Y8K) the mass of the Earth has increased (due to excessive space mining). As a result, the moon has moved further from the earth (the distance between the earth and the moon in the year 8000 is 4.06×108 mm ) and is now in a circular orbit. A lunar month remains at 29.5 days.
Calculate the mass of the earth in the year 8000 (Y8K)
M earth = ?kg
Astronomical observations of our milky way galaxy indicate that it has a mass of about 8x1011 solar masses. A star orbiting near the galaxy's periphery is 5.6x104 light years from its center.
a.) What should be the orbital period (in years) of that star be?
b.) If its period is 6.4x107 years instead, what is the mass (in solar masses) of the galaxy? Such calculations are used to imply the existence of "dark matter" in the universe and have indicated, for example, the existence of very massive black holes at the center of some galaxies.
