If a standard passenger aircraft can fly at 0.26 km/s (582 mph), how long (in yr) would it take to reach the Sun?
yr
How long (in yr) would it take to reach the galactic center? (Note: 1 pc = 3.1 ✕ 1013 km. The radius of the Sun's orbit around the galactic center is approximately 8,300 pc.)
yr
The Sun is moving at 220 ??/? around the Galactic Center at a more-or-less constant distance of 8.5 ???. To appreciate how remarkable this is, consider the following questions:
a) How massive would the Sun have to be for the Earth to have an orbital velocity of 220 km/s at 1 AU?
b) How fast would the Earth move if it was in orbit around the Sun at a distance of 8.5 kpc? Of course, you may ignore the effects of all other stars in this calculation.
Suppose you observe a star orbiting the galactic center at a speed of 1100 km/s in a circular orbit with a radius of 14 light-days. Calculate the mass of the object that the star is orbiting. Express your answer in solar masses to two significant figures.
