A "nebulous object" is seen at a galactic longitude of 150 degrees. If the radial velocity measured for this object is 50 km/s, then how far is this object from the Sun? (Calculate the "kinematic distance", assume a "flat rotation curve", that the distance from the Sun to the center of our Milky Way galaxy is 8.5 kiloparsec (kpc) and that the orbital velocity of the Sun around the center is 220 km/s.

Answer rating: 100% (QA)

To calculate the kinematic distance of the nebulous object from the Sun we will use the flat rotatio... View the full answer
