The discovery was made by measuring the star's radial velocity.

This display of radial velocity represents the overall wind field.

He also studied the radial velocities of close binary stars.

This made it possible for these to be looked at again using the radial velocity method.

This planet was detected by radial velocity and published on April 10, 2007.

It has a radial velocity toward the Sun of 21.7 km/s.

And we still have inward radial velocity of our own.

It also has an unusually high radial velocity at 83 km/second.

The radial velocity of a star is its motion toward or away from the Sun.

It has a radial velocity of +15.5 km/s away from the Sun.
