Let us imagine that the spectrum of a star is collected and we find the absorption line of Hydrogen-Alpha (the deepest absorption line of hydrogen in the visible part of the electromagnetic spectrum) to be observed at 656.5 nm instead of 656.3 nm as measured in a lab here on Earth. What is the velocity of this star in m/s? (Hint: speed of light is 3*10^8 m/s; leave the units off of your answer)

The time it would take for the Sun to consume all its hydrogen (if the Sun's luminosity remained constant) is
about 100 billion years. Why is this an unrealistic estimate of the lifetime of the Sun?
