What is the velocity of sun rays in space?

Light ray comes out in all direction from sun and hence the velocity is ZERO.

You can see the previous answer below and note there it is mentioned SPEED.

Above one is the Answer to the Question

The sun emits many different kinds of rays - visible, ultraviolet, X-ray, infrared, and radio. They all travel at the same speed through a vacuum, such as space: 299,792,458 m/s.

Most people are fine with using a rounded version of the number that is less cumbersome - 300,000,000 m/s, or 3 x 108 m/s.
