A bullet fired from a gun goes more or less at Mach 1, correct?
It's thirteen years to the sun at the speed of a bullet?

Spacecraft towards Mercury, or the Parker Solar Probe go much faster than that, take a few years to make it there, but they are doing so picking up speed in flybys of first Earth, then Venus, then Mercury, in several, ever tighter orbits.

It's both fun and illuminating to try and visualize these things in new ways. In this case, from the viewpoint of a bullet.
