: ~~ From what perspective? From sun, which doesn't move, we are moving quite quickly. From the earth, we are moving 3mph. It all depends on what you use a the static point. So while according to the spaceship you are only moving 3mph, but relative to the sun you are moving near or over the speed of light.
You're still moving under the speed of light relative to the sun. You're adding speeds which can't be added together without conversion. Remember, the spaceship is moving 0mph relative to itself. 3 + 0 = 3. That's all you can add together. When you consider speeds from outside a system, you have to remember that time distorts (slows down) as an object or system approaches light speed. And as a system's "time" slows down, so do speeds of any elements of that system.
